Urgent plzz help me thx

The balanced equation :

C₃H₈(g)+5O₂(g)→3CO₂(g)+4H₂O(g)

Given

The reaction of Propane(combustion)

Required

Balanced equation

Solution

Reaction

C₃H₈(g)+O₂(g)→CO₂(g)+H₂O(g)

Give a coefficient(the most complex compound = 1) :

C₃H₈(g)+aO₂(g)→bCO₂(g)+cH₂O(g)

Make an equation :

C, left = 3, right=b⇒b=3

H, left = 8, right=2c⇒2c=8⇒c=4

O, left = 2a, right=2b+c⇒2a=2b+c⇒2a=2.3+4⇒2a=10⇒a=5

The equation becomes :

C₃H₈(g)+5O₂(g)→3CO₂(g)+4H₂O(g)
