Answer:
The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.
Explanation:
How do you balance equations?
In general, however, you should follow these steps:
1. Count each type of atom in reactants and products.
2. Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.
3. Repeat steps 1 and 2 until the equation is balanced.
The oxidation number of chlorine in the reactant can be determined by K ion and O ion. K ion is +1 and O ion is -2. And the Cl is +5. The gas has the greatest entropy and the solid has the least. In the production, there are solid and gas. So it has more entropy than the reactants with solid only.
