Answer:

6. KCIO4 -> KCI + 2O2

7. Ni(OH)2 + H2SO4 → NiSO4 + 2H2O

8. 4Ga(Cn)3 + 3Sn(BrO3)4 → 3Sn(Cn4) + 4Ga(BrO3)3

9. 3Ca(NO3)2 + 2Fe → 2Fe(NO3)3 + 3Ca

Step-by-step explanation:

Balancing a chemical equation involves the following steps:

  1. Write the equation with the correct chemical formulas for the reactants and products.
  2. Count the number of atoms of each element on both sides of the equation.
  3. Adjust the coefficients of the reactants and/or products so that the number of atoms of each element on both sides of the equation is equal. This can be done by multiplying the coefficients by a whole number.
  4. Check that the equation is balanced by verifying that the number of atoms of each element is the same on both sides of the equation.
  5. If the equation involves charges, make sure that the total charge on both sides of the equation is equal by adjusting the coefficients of the ionic species as needed.

It is important to balance chemical equations because the law of conservation of mass states that the total mass of the reactants must equal the total mass of the products in a chemical reaction. Balancing chemical equations helps ensure that this law is satisfied.
