Question

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

Answer 1

The required balanced equation:

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

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 -

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