Chapter 9.5, Problem 9.30QAP

Interpretation Introduction

Interpretation:

To determine the mass of CO₂ produced from 45.0 g of propane if the reaction yield is 60.0 %.

  ${\text{C}}_3{H}_8\text{(g)}\text{+}5O_{\text{2}}\text{(g)}\stackrel{\Delta }{\to }3C{\text{O}}_2\text{(g)}\text{+}4H_2\text{O}\text{(g)}$

Concept Introduction:

A stoichiometric coefficient of a well-balanced chemical equation tells about the relative relation between moles of reactants used and moles of products formed.

Lets say we have a chemical reaction as:

  $\text{aA}\text{+bB}\to \text{cC}\text{+}\text{dD}$

If above reaction is well-balanced then,

a moles of A reacts with b moles of B to produce c moles of C and d moles of D.

Limiting reactant: It is reactant in a chemical reaction which limits the amount of products formed.

After complete utilization of limiting reactant, no more products are formed.
