Question

Balance the combustion reaction between propane and oxygen.
C ₃ H ₈+ O ₂→ CO ₂ + H ₂ O

Answer 1

`\huge \boxed{\mathrm{C_3 H_8 +5O_2 \Rightarrow 3CO_2 +4 H_2 O}}`

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

Step-by-step 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}`

Answer 2

The answer is C3H8 + 5O2 → 3CO2 + 4H2O .
