# Consider the balanced equation:math> C 3 H 8 ( g ) + 5 O 2 ( g ) → 3 CO 2 ( g ) + 4 H 2 O ( g ) at mole ratio enables you to calculate the number of moles of oxygen needed to react exactly with a given number of moles of C 3 H 8 ( g ) ? What mole ratios enable you to calculate how many moles of each product form from a given number of moles of C 3 H 8 ?

Interpretation Introduction

Interpretation:

To determine what ratio enables to calculate the number of moles of oxygen needed to react exactly with a given number of moles of propane gas and to determine what ratios enables to calculate the number of moles of carbon dioxides and water; products needed to react exactly with a given number of moles of propane gas.

Concept Introduction:

A balanced chemical equation is an equation that contains same number of atoms as well as of each element of reactants and products of reaction.

The burning of organic compounds in presence of oxygen or air which produces water and carbon dioxide with energy is said to be the combustion reaction. It is an exothermic reaction.

For example the combustion reaction of ethane is following:

2 C2H6(g) + 7 O2(g)Δ4 CO2(g) + 6 H2O(g)              Reactants                         Products

The general reaction of combustion as follows:

Organic compound + O2(g) Δ CO2 (g) + H2O (l)+energy.

Explanation

The burning of organic compounds in presence of oxygen or air which produces water and carbon dioxide with energy is said to be the combustion reaction. It is an exothermic reaction.

For example the combustion reaction of ethane is following:

2 C2H6(g) + 7 O2(g)Δ4 CO2(g) + 6 H2O(g)              Reactants                         Products

The balance combustion reaction of complete combustion of propane is as follows:

C3H8(g) + 5O2(g)Δ3 CO2(g) + 4 <
