little or no rainfall

high humidity

Answers

Answer 1

Hello! :p .

deserts are known to have little to no rain fall & drop to very low temperatures at night! I hope this helps!

Answer 2

Answer: little or no rainfall

Explanation: Precipitation, sunlight, and temperature are all abiotic factors.

Deserts have a lack of rainfall.

Some deserts are hot, some deserts can be cold too.

Abiotic factors are  extreme temperatures of the day and night  the fast winds  the strong amount of sunlight  scarcity of water

How many atoms are in 80.45g of magnesium

Answers

Answer:

see below

Explanation:

1. 1 mol Mg = 24.31 g = 6.02 *10^23 atoms

     calculate the number of atomsin 80.45g Mg

         Numberof atoms = 6.02*10^23 Mg atoms / 24.31 g * 80.45 g

                                    = 1.99*10^24 atoms

2.1 mol C-12 = 12.01g = 6.02 * 10^23 atoms

    calculate the mass using

                                       = 12.01 g C / 6.02*10^23 atoms * 100 atoms

                                       = 1.99 * 10^-21 g

Answer:

1.9926 * 10 ^24 

Explanation:

Molar Mass - Use Periodic table!

M ( Mg ) = 24.31 g / mole

n = 80.45 g : 24.31 g/mole = 3.31 moles

N a ( Avogadro`s constant ) = 6.02 * 10 ^23

N = Na * n = 6.02 * 10 ^24 * 3.31 = 19.926 * 10 ^23

Sodium carbonate (Na2CO3) reacts with acetic acid (CH3COOH) to form sodium acetate (NaCH3COO), carbon dioxide (CO2), and water (H2O). A chemist carries out this reaction in a bomb calorimeter. The reaction causes the temperature of a bomb calorimeter to decrease by 0. 985 K. The calorimeter has a mass of 1. 500 kg and a specific heat of 2. 52 J/g•K. What is the heat of reaction for this system? kJ.

Answers

Explanation:

Mass of bomb calorimeter, m = 1.5 kg = 1500 g

Temperature change of calorimeter, ΔT = - 0.985 K

Specific heat of calorimeter, c = 2.52 J/g K

To Find:

The heat of reaction for this system

Calculation:

The heat of reaction can be calculated by the given formula:

Q = mcΔT

⇒ Q = 1500 × 2.52 × (- 0.985)

⇒ Q = - 3723.3 J       (-ve sign shows heat is given by calorimeter)

- So the heat of reaction is -3723.3 J or -3.7233 kJ

Taking into account the definition of calorimetry, the heat of reaction for the system is  -3,723.3 J or -3.7233 kJ.

In first place, calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

In this way, between heat and temperature there is a direct proportional relationship.

The constant of proportionality depends on the substance that constitutes the body and its mass, and is the product of the specific heat by the mass of the body.

So, the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case, you know:

Q= ? c= 2.52 [tex]\frac{J}{gK}[/tex] m= 1.500 Kg= 1500 g ΔT= -0.985 K is negative because the temperature decreases.

Replacing in the expression to calculate heat exchanges:

Q= 2.52[tex]\frac{J}{gK}[/tex]× 1500 g× (-0.985 K)

Solving:

Q= -3,723.3 J= -3.7233 kJ

Negative sign shows heat is given by calorimeter.

In summary, the heat of reaction for the system is  -3,723.3 J or -3.7233 kJ.

A tank of syngas produced by coal gasification contains 60.0% carbon monoxide, 30.0% hydrogen, and 10.0% carbon dioxide. What is the mass of hydrogen (in g) in 1.00 cubic meter of this syngas mixture at 1.00 atm and 25.0 °C? (1 m³ = 1000 L)

Answers

Considering the ideal gas law, the mass of hydrogen is 24.552 grams.

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P× V = n× R× T

In this case, you know:

P= 1 atmV= 1 m³= 1000 Ln= ?R= 0.082[tex]\frac{atmL}{molK}[/tex]T= 25 °C= 298 °K

Replacing in the ideal gas law:

1 atm× 1000 L = n× 0.082[tex]\frac{atmL}{molK}[/tex]× 298 K

Solving:

[tex]n=\frac{1 atmx1000 L}{0.082 \frac{atmL}{molK}x298 K}[/tex]

n= 40.92 mol

The mol of syngas mixture is 40.92 mol.

Syngas mixture contains 30.0% hydrogen. So, there is a mol fraction of [tex]x_{hydrogen} =[/tex]0.3 . Thus, the mols of hydrogen in syngas mixture is calculated as:

40.92 moles of syngas mixture× 0.3= 12.276 moles of hydrogen

Finally, being the molar mass of hydrogen H₂ 2 [tex]\frac{g}{mole}[/tex], then the mass is:

[tex]12.276 molesx\frac{2 grams}{1 mole}[/tex]= 24.552 grams

In summary, the mass of hydrogen is 24.552 grams.

Answer:

Explanation:

Metals are lustrous which gives them a property of having Shiny surfaces

The valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous  property of metals.

What are valence electrons?

Valence electrons are defined as a negatively charged particle that can be shared or transmitted between atoms that is found in the outermost shell of an atom. Valence electrons have a crucial role in determining how an atom will behave. The electrical configurations of elements can be used to find valence electrons. The total number of valence electrons in that element is then determined by counting the number of electrons in the outermost shell.

When newly treated, polished, or broken, a material takes on a bright look and conducts electricity and heat reasonably well. Metals are typically ductile and malleable. These traits are the result of the metallic bond that connects the atoms or molecules of the metal.

Thus, the valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous  property of metals.
