Write a balanced equation for the combustion of liquid penetrate C5H12, in which it combines with gaseous oxygen to form gaseous carbon dioxide and gaseous water?

1 Answer

Answer:

# C_5H_12 + 8 O_2 rarr 5CO_2 + 6 H_2O#

Explanation:

your equation works. However, it is better to use the smallest possible coefficients. Divide your by 2. It still works.

Start by using the 5 carbons in the hydrocarbon to form 5 carbon dioxide. Then use the 12 hydrogens to form 6 waters. Then count up the oxygen atoms needed.

# 5 xx O_2 = 10 O#
# 6 xx O_1 = 6 O#
= # 16 O#
There must be 16 oxygens on the left or reactants to balance the equation. So

# 8 xx O_2 = 16 O#

so

# 1 xx C_5H_12 + 8 xx O_2 = 5 xx CO_2 + 6 xx H_2O#
