what is the accepted iupac name for the compound mg3p2?

Answer:

Negative ion with one extra electron.

BRAINLIST Pls

Anions are the name for ions that have a negative charge. The body contains several common chemicals as ions. Sodium, potassium, calcium, chloride, and bicarbonate are typical examples.

Negatively charged electrons are called anion. When non-metals gain electrons, they are produced. They absorb one or more electrons. They have a negative charge overall as a result. The ion concentration iodide ( I- ), chloride ( Cl- ), and hydroxide are among examples ( OH– ).

The electrode where reduction takes place in any electrochemical cell  is characterized as the cathode. On the other extreme, the positive electrode will draw anions, or negative ions, to itself.

Thus, when an atom obtains electrons, it transforms into the negatively-charged ion known as an anion.

There are quite a few ways to add moisture into the air without a humidifier

A few things that can help add moisture are hanging your clothing to dry. hang drying your damp clothes will add moisture to the air over time as it evaporates and it will make your house smell like fresh clothes.

Another thing is a bath,  allow the water to cool off and leave the bathroom door open, the steam will add moisture to the air as the water cools.

This might seem silly but putting bowls or vases of water out on the windowsill on a sunny day mill moistens the air as it evaporates.

You can also get houseplants, moisture evaporates from the leaves and stems of plants. transpiration can help increase the humidity in your home.

not sure if this is the answer you were looking for but if so im glad i could help. have a great day!

Explanation:

Answer:

Decane doesn't have any free electrons because all the electrons of carbon is used for bonding.

A solution of the ionic salt Lihco3 would have 11.3 pH.

In chemistry, salt exists as a chemical compound consisting of an ionic group of positively charged cations and negatively charged anions, which results in a combination with no net electric charge. A common example stands table salt, with positively charged sodium ions and negatively charged chloride ions.

The fragment ions in a salt compound can be either inorganic, such as chloride (Cl−), or organic, such as acetate (CH3CO−2). Each ion can be either monatomic, such as fluoride (F−), or polyatomic, such as sulfate (SO2−4).

Explanation:

A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without itself being consumed by the reaction.

Activation energy is the minimum amount of energy required for a chemical reaction to proceed in the forward direction.

A catalyst increases the reaction rate by providing an alternative pathway or mechanism for the reaction

Answer:

BeF2

Explanation:

The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.

The valence electron of an atom determines how an atom goes into bonding.

Beryllium(Be) has 4 electron and has 2 valence electron. To fulfil the octet rule, it can easily give out this 2 electron during bonding.

Fluorine(F) has 9 electrons and 7 valency electrons. To fulfil the octet rule, it readily accepts a single electron.

The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.

This means 1 atom of beryllium combines with 2 atoms of fluorine to form beryllium fluoride. The beryllium give its 2 valency electrons to the 2 atoms of fluorine. The 2 atoms of fluorine will now have a valency electron of 8 each. The octet rule has been fulfilled at this point.

By applying Charles law, the final volume of the gas is equal to 42 mL.

Given the following data:

To find the final volume of the gas, we would apply Charles law:

Charles law states that when the pressure of an ideal gas is kept constant, the volume of the gas is indirectly proportional to the absolute temperature of the gas.

Mathematically, Charles law is given by the formula;

[tex]\frac{V}{T} =k\\\\\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

Where;

Substituting the given parameters into the formula, we have;

[tex]\frac{140}{400} = \frac{V_2}{120} \\\\140 \times 120 = 400V_2\\\\16800 = 400V_2\\\\V_2 = \frac{16800}{400}[/tex]

Final volume = 42 mL.

Considering the definition of STP conditions, 28 grams of O₂ will ocupy at STP 19.6 L.

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

On the other side, the molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

In this case, you  have 28 g of O₂. The molar mass es 32 [tex]\frac{g}{mole}[/tex]

Next, you can apply the following rule of three: if 32 grams of the compound are contained in 1 mole, 28 grams are contained in how many moles?

[tex]number of moles=\frac{28 gramsx1 mole}{32 grams}[/tex]

number of moles= 0.875 moles

Now, you can apply the following rule of three: if by definition of STP conditions 1 mole of O₂ occupies a volume of 22.4 liters, 0.875 moles occupies how much volume?

[tex]volume=\frac{0.875 molesx22.4 L}{1 mole}[/tex]

volume= 19.6 L

Finally, 28 grams of O₂ will ocupy at STP 19.6 L.
