Question

A Certain Volume of CO2 is passes over red hot coke then it gives 700 dm³ of CO and 50 dm³ of CO2 . Find The Initial Volume Of CO2 passed Over The Red Hot Coke ?​

Answer 1

Answer:

CO

2

(g)+C(s)→2CO(g)

0.5L

Explanation:

Total volume =700ml=0.7L

(0.5−x)+(2x)=0.7

0.5+x=0.7

x=0.2L = 200ml

CO

2

(g)=0.5x=0.5−0.2=300ml

CO(g)=2x=0.2=0.4=400ml

Therefore, the correct option is D.
