In a combustion reaction a hydrocarbon reacts with oxygen to produce CO2 and H2O.
To balance: add coefficients so that number of atoms of each element on both sides are equal.
2C2H4(OH)2 + 5 O2 (g) → 4CO2 (g) + 6H2O (l)
2 4 C - 1 4
6 12 H - 2 12
Determine the balanced equation for the reaction that occurs when ethylene glycol, C2H4(OH)2, burns in air.
a) C2H4(OH)2 (l) + 3 O2 (g) → 2 CO2 (g) + 3 H2O(g)
b) C2H4(OH)2 (l) + 5 O(g) → 2 CO2 (g) + 3 H2O(g)
c) 2 C2H4(OH)2 (l) ) + 5 O2 (g) → 4 CO2 (g) + 6 H2O(g)
d) 4 C2H4(OH)2 (l) + 10 O2 (g) → 8 CO2 (g) + 12 H2O(g)
e) C2H4(OH)2 (l) + 5/2O2 (g) → 2 CO2 (g) + 3 H2O(g)
