Question

challenge problem: give it your best shot! c₂h₆ + o₂ → co₂ + h₂o

Explanation:

Step1: Balance carbon atoms

$$\ce{C2H6 + O2 -> 2CO2 + H2O}$$

Step2: Balance hydrogen atoms

$$\ce{C2H6 + O2 -> 2CO2 + 3H2O}$$

Step3: Balance oxygen atoms

$$\ce{2C2H6 + 7O2 -> 4CO2 + 6H2O}$$

Answer:

$$\ce{2C2H6 + 7O2 -> 4CO2 + 6H2O}$$
