How to differ if a particle is a metal or a non metal

Answers

Answer 1

The properties of metals and nonmetals are different, and these differences can be used to differentiate between them. Here are some characteristics that can be used to identify whether a particle is a metal or a nonmetal:

Physical appearance: Generally, metals are shiny, lustrous, and have a metallic luster. Nonmetals, on the other hand, are typically dull, lack luster, and are not shiny.

Conductivity: Metals are good conductors of heat and electricity, while nonmetals are poor conductors.

Malleability and ductility: Metals are generally malleable and ductile, meaning they can be easily shaped or drawn into wires. Nonmetals, however, are brittle and not malleable or ductile.

Chemical properties: Metals tend to form positive ions, while nonmetals tend to form negative ions.

By examining these properties, it is possible to differentiate between metals and nonmetals.

Answer 2

Two main types of elements with different characteristics are metals and nonmetals. By looking at a particle's physical and chemical characteristics, one may tell if it is a metal or nonmetal.

The following characteristics of metals and nonmetals can be used to distinguish them: Physical Characteristics Nonmetals are drab and lack a metallic shine, whereas metals are often brilliant and have one. Metals can usually be easily formed into various shapes because they are malleable and ductile. Nonmetals have a tendency to break readily and are fragile. Nonmetals are weak conductors of heat and electricity compared to metals. Except for mercury, metals are typically solid at room temperature. At room temperature, nonmetals might be solid, liquid, or gas.

what would happen to the temperature and physical state of 1 mol of liquid diethyl ether at its standard boiling point if its molar enthalpy of vaporization (26.52 kj/mol) were added?

Answers

When 1 mol of liquid diethyl ether at its standard boiling point is given an enthalpy of vaporization of 26.52 kJ/mol, the temperature of the liquid will remain the same, but the physical state of the diethyl ether will change from liquid to vapor.

The enthalpy of vaporization is the energy required to convert one mole of a liquid into a vapor and is also known as the heat of vaporization. When the enthalpy of vaporization is applied to liquid diethyl ether, it causes the liquid to become a vapor.

In order to understand this concept, it is helpful to look at the thermodynamic process of vaporization, or boiling. Vaporization involves the conversion of liquid to a gas at the standard boiling point by the absorption of energy, which is provided in the form of heat.

During vaporization, the liquid molecules move quickly and gain enough energy to escape the surface of the liquid and form a gas. This process is also reversible, so as the vaporized molecules lose energy, they can condense back into the liquid state.

Therefore, the temperature remains the same, but the liquid is converted to a vapor. This vapor can eventually condense back into liquid form, depending on the temperature and pressure of the system.

So, a mass of naphthalene between 12.777 g and 12.857 g will be appropriate.

2-bromo-2-methylpropane + naphthalene → product(s)

To calculate the mass of naphthalene required for the reaction, we need to know the mole ratio of 2-bromo-2-methylpropane to naphthalene in the balanced equation.

From the balanced equation, we can see that the mole ratio is 1:1.

This means that one mole of 2-bromo-2-methylpropane will react with one mole of naphthalene.

First, we need to determine the number of moles of 2-bromo-2-methylpropane that we have in the flask.

Let's assume we have 0.1 moles of 2-bromo-2-methylpropane.

To react stoichiometrically, we will need 0.1 moles of naphthalene.

Calculate the number of vanadium atoms in a 50.0 sample of vanadium oxide (V2O5)

Answers

To calculate the number of vanadium atoms in a 50.0 g sample of V2O5, we need to use the molar mass of V2O5 and the Avogadro's number.

1. First, let's find the molar mass of V2O5:
2 x atomic mass of V + 5 x atomic mass of O
= 2 x 50.94 g/mol + 5 x 16.00 g/mol
= 149.88 g/mol

2. Next, let's calculate the number of moles of V2O5 in the sample:
50.0 g / 149.88 g/mol = 0.333 mol

3. Since V2O5 contains 2 vanadium atoms per molecule, we need to multiply the number of moles by 2 to get the total number of vanadium atoms:
0.333 mol x 2 = 0.666 mol

4. Finally, we can use Avogadro's number (6.022 x 10^23) to convert moles to atoms:
0.666 mol x 6.022 x 10^23 atoms/mol = 4.01 x 10^23 vanadium atoms

Therefore, there are approximately 4.01 x 10^23 vanadium atoms in a 50.0 g sample of V2O5.

Answers

Answer:

The molar mass of CuO is 63.55 g/mol for copper and 15.9994 g/mol for oxygen, giving a total molar mass of 79.55 g/mol.

To calculate the number of moles in 4.0 g of CuO, we can use the formula:

moles = mass / molar mass

moles of CuO = 4.0 g / 79.55 g/mol

moles of CuO = 0.0502 mol

Therefore, there are 0.0502 moles in 4.0 g of CuO.

grams of Fe₂O3:
g Fe₂0;

Answers

71.86 grams of Fe2O3 can form from 21.6 grams of O2.

How to solve

To determine the amount of Fe2O3 that can form from 21.6 g of O2, we need to use the balanced chemical equation and the stoichiometry of the reaction.

According to the balanced chemical equation:

4 Fe(s) + 3 O2(g) → 2 Fe2O3(s)

The stoichiometric ratio of O2 to Fe2O3 is 3:2. This means that for every 3 moles of O2, 2 moles of Fe2O3 are produced.

To calculate the amount of Fe2O3 formed, we need to first convert the mass of O2 given to moles:

n(O2) = m(O2) / M(O2)

where:

m(O2) is the mass of O2 given in the problem, which is 21.6 gM(O2) is the molar mass of O2, which is 32.00 g/moln(O2) = 21.6 g / 32.00 g/mol = 0.675 mol O2

Next, we can use the stoichiometric ratio to calculate the number of moles of Fe2O3 formed:

n(Fe2O3) = 2/3 x n(O2)

n(Fe2O3) = 2/3 x 0.675 mol = 0.450 mol

Finally, we can convert the number of moles of Fe2O3 to grams using its molar mass:

m(Fe2O3) = n(Fe2O3) x M(Fe2O3)

where:

M(Fe2O3) is the molar mass of Fe2O3, which is 159.69 g/molm(Fe2O3) = 0.450 mol x 159.69 g/mol = 71.86 g

Therefore, 71.86 grams of Fe2O3 can form from 21.6 grams of O2.

Answers

The grams of CO2 that could have been produced according to the reaction is 21.2 grams.

We apply the stoichiometric principles to calculate the potential yield of a particular mixture of chemicals. To determine the mole to mole correlations between the chemical species in stoichiometry, we apply the balanced chemical equation. The theoretical yield is the highest yield that can be estimated from the starting reagent quantities. The amount collected is known as the actual yield, and frequently we discover that the theoretical yield is not achieved.

The balanced chemical equation is:

2CO + O₂ → 2CO₂

Molar Mass CO = 28.0 grams per mole

Molar Mass O2 = 32.0 grams per mole

Molar Mass CO2 = 44.0 grams per mole

We determine the maximum quantity of carbon dioxide that may be produced from each reagent based on their initial concentrations. This assumes that there is an excess of the other reagent.

13.5 g CO x 1 mol CO / 28 g CO x 2 mol CO₂ / 2 mol CO x 44 g CO₂

= 21.2 g CO₂

What is Ideal Gas Law?

The ideal gas law is a mathematical equation that describes the behavior of an ideal gas under specific conditions. It relates the pressure (P), volume (V), temperature (T), and amount of substance (n) of an ideal gas, using the following equation:

PV = nRT

where R is the universal gas constant, which has a value of 8.31 J/(mol·K) in SI units.

The ideal gas law assumes that the gas molecules are point masses that do not interact with each other except through perfectly elastic collisions, and that the gas occupies a large volume compared to the size of the molecules. In reality, most gases do not behave exactly like ideal gases, especially at high pressures or low temperatures.

However, when a gas changes, we may need to use different laws or equations to describe the behavior of the gas, depending on the conditions and factors involved. For example, if the volume of a gas changes at a constant temperature and pressure, we would use Boyle's Law, which describes the relationship between volume and pressure.

Answers

Answer:

0.124 moles of water  (2.24 grams)

Explanation:

The moles of water produced by the combustion of butane requires 3 steps.  The first is the primary challenge of this question:

1)  Balance the Reaction

 Write the reaction using just chemical formulas.  We know that a combustion reaction produces carbon dioxide and water, so let's start there:

  C4H10 + O2 = CO2 + H2O  

This looks correct - there are no elements that are just on one side (unaccounted for).  Now we need to balance the reaction.  Use pencil and paper for this step.  We can see that although butane consists of only two elements, carbon and oxygen, there are a lot of them.  It is often a good idea to find the most complex molecule and assign it a coefficient of 1 (in pencil), just to get started.

 a)  1C4H10 + O2 = CO2 + H2O  

Now distribute the atoms from butane to the products by assigning them coefficients:

  b)  1C4H10 + O2 = 4CO2 + H2O

The 4 carbons require that we add a coefficient of 4 to CO2, since it is the only possible destination for the carbons.  

The 10 hydrogens must all go to the H2O, so add a 5 to the H2O:

  c)  1C4H10 + O2 = 4CO2 + 5H2O

Now that the carbons and hydrogens are accounted for, work on the oxygens.  As written in c, there are 2 O atoms from the reactants, and (8+5) = 13 O atoms from the products.  This is an annoying outcome:  There will always be an even number of O atoms coming from the O2.  so there is no whole number we can add as the O2 coefficient that will produce an odd number of O atoms.  But an easy resolution is, temporarily, use a fraction for the number of O2 molecules.  If we use a coefficient of 6.5 for the O2, the equation will balance.

 d)  1C4H10 + 6.5O2 = 4CO2 + 5H2O

But we can't have 1/2 of a molecule, so let's multiply all coefficents by 2, so that they are all whole numbers:

 e)  2C4H10 + 13O2 = 8CO2 + 10H2O

That's why we use a pencil.

2.  Determine the molar ratio of the water to the butane

The important thing to note is that the balanced equation tells us that we should expect 10 moles of H2O for every 2 moles of C4H10, a molar ratio of 5/1 moles water/mole butane.  This is a conversion factor:  (5 moles H2O)/(1 mole C4H10)

3.  Find the moles of water produced

It took a while to get to this point, "but the end is near."  We are given 2.49x10^-2 moles of butane.  Simply multiply that times the molar ratio we derived above:

(2.49x10^-2 moles butane)*[(5 moles water)/(1 mole butane)] = 0.124 moles of water

A lot of work for 2.24 grams of water.  I suggest finding a water fountain instead.

Depending on where a force, fulcrum, and load are, the three classes differ from one another. The centre of gravity of a first-class lever is situated here, halfway between both the input force or the output force.

Name the three lever classes and describe each.

Depending upon where the power supply, fulcrum, or load are located, there are three different kinds of levers. The fulcrum of a class 1 lever is situated between both the input force or the load. The load is situated between both the fulcrum and the input force of a class 2 lever. Levers with the input force located between the fulcrum as well as the load are classified as class 3 levers.

What is third class lever known as?

These are the types of levers where the weight is on one end, the fulcrum is in the middle, as well as the force is applied. The arrangement is shown as a weight-force-fulcrum. In this situation, we need to exert greater force in order to move the weight.

Explain, in terms of molecular polarity, why oxygen gas has low solubility in water. (MUST INCLUDE BOTH OXYGEN AND WATER IN ANSWER.)

Answers

Answer:
O2 gas has low solubility in water because oxygen is a non-polar molecule whereas H2O (or water) is polar (due to the unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule - with a bent molecular structure).

Explanation:

Oxygen gas is a diatomic molecule, meaning that is has 2 oxygen molecules that are linked using a double bond. As a result, O2 gas can only dissolve in water (or H2O) by way of a dipole-induced dipole interaction or Van Der Waals. Another reason may be that O2 gas is covalently bonded (can't form ions) whereas H2O is ionically bonded with one another.

Oxygen gas has low solubility in water according to polarity and non polarity theory.

What is solubility?

Solubility is the amount of solute that can be dissolved in a solvent. Generally, the solubility of most solutes increases with an increase in the temperature of the solvent.

The property that can help sugar molecules or salt crystals to dissolve is known as solubility.

Factors that affect solubility include:

Concentration of the solute

Temperature

Pressure

Polarity of the solute and the solvent

It has been observed that like molecules dissolve in like solvent. Polar molecules can only be soluble in polar solvent. Water is a polar solvent but Oxygen molecule is linear molecule with only Oxygen atoms hence no polarity.

Therefore, Oxygen gas has low solubility in water according to polarity and non polarity theory.

Answers

Many common things you use regularly are colloids except alloy.

What is an alloy?

An alloy is a solid solution composed of two or more metals or a metal and a non-metal element. In contrast, colloids are mixtures where one substance is dispersed throughout another substance in the form of small particles that do not settle out.

What are colloids?

Colloids are mixtures composed of particles that are intermediate in size between those of a solution and a suspension. These particles are typically between 1 and 1000 nanometers in diameter, which is too small to be seen with the eye, but large enough to scatter light, giving the mixture a cloudy or opaque appearance.

Milk, hair, spray, and paint are all examples of colloids.
