Question

Which number should be placed before H20 on the products side of the equation to

make the equation balanced? C3H8 +502 — 3C02 +____H20
O2
05

Answer 1

The required balanced equation:

`C_3H_8 +5O_2 = 3CO_2 + 4H_2O`

Step-by-step explanation:

• Propane when reacts with oxygen it gives carbon dioxide and water.

• In order to make the equation balanced at both ends of the equation,

Add 4 as a coefficient before on L.H.S (Left Hand Side) of Equation.

• Therefore, the required balanced equation is:

Propane, when added with 5 molecules of Water, yields 3 molecules of Carbon Dioxide and 4 molecules of water, as shown in the below equation -

`C_3H_8 +5O_2 = 3CO_2 + 4H_2O`
