Question

Determine the volume of carbon dioxide produced during the reaction of 33.6L of oxygen with enough acetylene (C2H2) at stp.

Answer 1

Balanced chemical reaction given by

`\\ \rm\rightarrowtail 2C_2H_2+5O_2\longrightarrow 4CO_2+2H_2O`

moles of O_2.

• 33.6/22.4=1.5mol

Now

• 5mol of O_2 produces 4mol CO_2
• 1mol of O_2 produces 0.8mol CO_2

1.5mol produces:-

• 1.5(0.8)=1.2mol CO_2

Volume of cO_2

• 1.2(22.4)=26.88L[/tex]
