Answer 2

Balancing Chemical Equations

a) Balancing the equation FeCl2 + Cl2 = FeCl3

The balanced chemical equation for the reaction between FeCl2 and Cl2 to form FeCl3 is:

2FeCl2 + Cl2 = 2FeCl3

This equation is balanced because the number of atoms for each element is the same on both sides of the equation.

b) Balancing the equation KHSO4 = H2O + K2S2O7

The balanced chemical equation for the reaction where KHSO4 decomposes into H2O and K2S2O7 is:

2KHSO4 = H2O + K2S2O7 + SO3

This equation is balanced because the number of atoms for each element is the same on both sides of the equation.
