Answer:

2 K(s) + Cl₂ (g) --> 2 KCl(s)

Explanation:

Potassium will just be K

Chlorine gas is part of BrIClHOF, which are diatomic gasses. So Cl₂

Looking at the periodic table potassium K has an ion charge of +1 and chlorine Cl has an ion charge of -1, so in a balanced compound they will be written as KCl

Balancing the amounts of each will lead to 2 K(s) + Cl₂ (g) --> 2 KCl(s)

The product side of a chemical reaction is shown.

Inga [223]

The number that represents the coefficient on the product side of the chemical reaction, $-- > 7Ti_2(SO_4)_3$ is 7.

<h3>Coefficients of chemical equations</h3>

In equations representing chemical reactions, the coefficient of each reactant or product of a reaction is the number that comes on the left-hand side just before the chemical formula.

The coefficient of each species in a chemical reaction is obtainable when the equation of the reaction is balanced.

For example, in the following equation: 2A + B = 3C + D

The coefficients of A, B, C, and D are 2, 1, 3, and 1 respectively.

Applying this to the product side of a chemical reaction; $-- > 7Ti_2(SO_4)_3$

It means that the coefficient of the product is 7.

How many hydrogen atoms are in 5.20 mol of ammonium sulfide?

Fofino [41]

1) Molecular formula of ammonium sulfide

(NH4)2 S

2) That means that there are 2*4 = 8 atoms of hydrogen in each molecule of ammoium sulfide, so in 5.20 mol of molecules will be 8 * 5.20 mol = 41.6 moles of atoms of hydrogen

3) To pass to number of atoms multiply by Avogadro's number: 6.022 * 10^23

41.6 moles * 6.022 * 10^23 atoms / mol = 250.5 * 10^23 = 2.50 * 10^25 atoms

Answer: 2.50 * 10^25
