Question

When the complete combustion of hexane takes place, how many water molecules are formed from one hexane molecule?

science chemistry

Answer 1

Answer #1

The reaction is:
C6H14 + O2 --> CO2 + H2O

Balance C:
C6H14 + O2 --> 6CO2 + H2O

Balance H:
C6H14 + O2 --> 6CO2 + 7 H2O

Balance O:
C6H14 + 19/2 O2 --> 6CO2 + 7 H2O

The equation is balanced
From 1 molecule of C6H14, 7 moles of H2O is formed

Answer: 7

Answer 2
