Question

The chemical reaction that occurs in a gas grill is the combustion of propane, C3H8. Write a balanced equation for this reaction. (Include states of matter.)

Answer 1

C3H8 (liquid) + 5O2 (gas) ➡️ 3CO2 (gas) + 4H2O (liquid)

Answer 2

Answer:

$\Large \boxed{\mathrm{C_3 H_8 \ (g)+5O_2 \ (g) \Rightarrow 3CO_2 \ (g)+4 H_2 O \ (l)}}$

$\rule[225]{225}{2}$

Explanation:

$\sf C_3 H_8 +O_2 \Rightarrow CO_2 + H_2 O$

Balancing Carbon atoms on the right side,

$\sf C_3 H_8 +O_2 \Rightarrow 3CO_2 + H_2 O$

Balancing Hydrogen atoms on the right side,

$\sf C_3 H_8 +O_2 \Rightarrow 3CO_2 +4 H_2 O$

Balancing Oxygen atoms on the left side,

$\sf C_3 H_8 +5O_2 \Rightarrow 3CO_2 +4 H_2 O$

$\rule[225]{225}{2}$
