Chapter 14, Problem 125A

Interpretation Introduction

Interpretation:

The moles of Bi₂O₃have to be calculated.

Concept introduction:

Mole: The mole is the unit which is used to measure the amount of a substance. A mole can be defined as the number of carbon atoms which is present in 12 g of pure carbon-12. A mole contains 6.023 × 10²³ particles.

Answer to Problem 125A

12.6 moles of CO₂ can be produced from 8.4 mol Bi₂O₃.

Explanation of Solution

$2B{i}_2{O}_3(s)+3C(s)=4Bi(s)+3C{O}_2(g)$

From the above balanced chemical equation, it can bestated that two mole of bismuth (III) oxide reacts with three moles of carbon to produce four moles of bismuth and three moles of CO₂.

3moles of CO₂is produced from 2moles of bismuth (III) oxide.

So, 12.6 moles of CO₂ can be produced from = $\frac{2molB{i}_2{O}_3\times 12.6molC{O}_2}{3molC{O}_2}=8.4molB{i}_2{O}_3$.
