CHALLENGE QUESTIONS: BALANCE THE EQUATIONS BELOW.

A. ___ NaNO3 + ___ PbO  ___ Pb(NO3)2 + ___ Na2O





B. ___ Ca3P2 + ___ H2O  ___Ca(OH)2 + ___ PH3





C. ___Fe2O3 + ___ CO  ___Fe + ___ CO2





D. ___NH3 + ___ O2  ___ NO2 + ___ H2O





E. ___FeS + ___O2  ___Fe2O3 + ___SO2





F. ___ C3H6O2 + ___ O2  ___ CO2 + ___ H2O

Answer 1

In balancing reaction equations, The number of atoms of each element on both sides of the reaction equation must be the same.

The major rule that guides the balancing of chemical reaction equations is that the total number of atoms of each element on the right hand side of reaction equation is equal to the total number of atoms of the same element on the left hand side of the reaction equation. For each of the equations shown;

• 2NaNO3 + PbO -------> Pb(NO3)2 + Na2O

• Ca3P2 + 6H2O→ 3Ca(OH)2 + 2PH3

• Fe2O3 + 3CO ------> 2Fe + 3CO2
• 4NH3 + 7O2 ------> 4NO2 + 6H2O
• 4FeS + 7O2   -----> 2Fe2O3 + 4SO2
• 2C3H6O2 + 7O2 -----> 6CO2 +6H2O
