Question

Faça a combustão completa e incompleta para os compostos abaixo :
A) C6H14

B) C2H2

Answer 1

a) $\text{C}_6\text{H}_{14}+\text{O}_2 \Longrightarrow \text{CO}2 + \text{H}_2\text{O}$

Balanceando:

$\text{C}_6\text{H}_{14}+\dfrac{19}{2}\text{O}_2 \Longrightarrow 6\text{CO}_2+7\text{H}_2\text{O}$

$\boxed{2\text{C}_6\text{H}_{14}+19\text{O}_2 \Longrightarrow 12\text{CO}_2+14\text{H}_2\text{O}}$

b) $\text{C}_2\text{H}_2+\text{O}_2 \Longrightarrow \text{CO}_2+\text{H}_2\text{O}$

Balanceando:

$\text{C}_2\text{H}_2+\dfrac{5}{2}\text{O}_2 \Longrightarrow 2\text{CO}_2 + \text{H}_2\text{O}$

$\boxed{2\text{C}_2\text{H}_2 + 5\text{O}_2 \Longrightarrow 4\text{CO}_2 + 2\text{H}_2\text{O}}$
