Concept: Balancing Chemical Reactions

Problem: Using your newly-found equation balancing knowledge, balance the following equations:1) ___ C4H8 + ___ O2 → ___ CO2 + ___ H2O2) ___ Ga(OH)3 + ___ KF → ___ KOH + ___ GaF33) ___ V + ___ ZnBr2 → ___ VBr3 + ___ Zn

FREE Expert Solution

Unbalanced Chemical Reaction:   

A.) C8H18(l) + O2(g) CO2(g) + H2O(g)

1. Balance the non-oxygen and non-hydrogen elements first: C

C4H8 +  O2 → 4 CO2 +  H2O

2. Balance Hydrogen

C4H8 +  O2 → 4 CO2 +  4 H2O

3. Balance Oxygen

C4H8 +  6 O2 → 4 CO2 +  4 H2O

4. Make sure that all the coefficients are whole numbers

C4H8 +  6 O2 → 4 CO2 +  4 H2O

Balanced Reaction Equation:

C4H8 +  6 O2 → 4 CO2 +  4 H2O
