Question

The balanced equation for combustion in an acetylene torch is shown below:

Answer 1

Answer:

The answer to your question is a) 70 moles of CO₂

                                                     b) 67.2 moles of CO₂

Explanation:

Data

moles of C₂H₂ = 35

moles of O₂ = 84

Balanced chemical equation

                 2C₂H₂  +  5O₂   ⇒   4CO₂  +  2H₂O

Process

1.- Moles of CO₂

                2 moles of C₂H₂ ------------------- 4 moles of CO₂

              35 moles of C₂H₂ -------------------  x

                                         x = (35 x 4)/2

                                        x = 70 moles of CO₂

2.- Moles of CO₂

                5 moles of O₂ ----------------------- 4 moles of CO₂

               84 moles of O₂ -----------------------  x

                                  x = (84 x 4) / 5

                                  x = 67.2 moles of CO₂
