# For each of the following balanced reactions, calculate how many moles of each product would be produced by complete conversion of 0.50 mole of the reactant indicated in boldface. Indicate clearly the mole ratio used for the conversion.msp;  2 H 2 O ( l ) → 2 H 2 O ( l ) + O 2 ( g ) msp;  2 KClO 3 ( s ) → 2 KCl ( s ) + 3 O 2 ( g ) msp;  2 Al ( s ) + 6 HCl ( a q ) → 2 AlCl 3 ( a q ) + 3 H 2 ( g ) msp;  C 3 H 8 ( g ) + 5 O 2 ( g ) → 3 CO 2 ( g ) + 4 H 2 O ( g )

Interpretation Introduction

(a)

Interpretation:

To calculate the moles of each product in the given reaction

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.

Mass of any substance can be calculated as follows:

Mass in gram = Number of moles×Molar mass

Number of moles can be calculated as follows;

Number of moles=mass in gmolarmass.

Explanation

The limiting reactant in a particular reaction has due to following properties:

1. Limiting reactant completely reacted in a particular reaction.
2. Limiting reactant determines the amount of the product in mole.

If any reactant left after competitions of reaction, thus it is said to excess reactant.

The balance chemical equation is as follows:

2H2O2(l) 2H2O(l)+ O2(g)

Given:

Moles of H2O2 = 0.50 mole

Calculation:

Numbers of moles of products are calculated as follows:

0.50 moles H2O2×1.00 mole O22

Interpretation Introduction

(b)
