Question

find the volume of co2 at stp formed by the combustion of 14g of ethene​

Answer 1

Answer:

24 dm cube.

Explanation:

Balanced chemical equation for the reaction:

C2H4 + 3O2→ 2CO2 + 2H2O

Molar mass of C2H4= 2*12+4=28

Mole of 14 g of C2H4= 14/28=0.5mol

Ratio of C2H4:CO2=1:2

therefore 0.5mol C2H4 will produce=2*0.5= 1 mol of CO2

Volume of 1 mol of CO2= 1*24=24 dm cube.

Ans:24 dm cube.
