Question

Calculate mass of oxygen required to burn 14 g and C2H4 completely

Answer 1

C2H4 burns as follows,

C2H4 + 3O2---> 2CO2+ 2H2O

To burn 26 g of C2H4, 96 g of oxygen is reqd.

∴ To burn 14 g of C2H4, 96/26 x 14= 51.7 g of oxygen is reqd.

Therefore, to burn 14 g of C2H4 completely, 51.7 g of O2 is reqd. C2H4 is called Ethene.

Thank u very much.

Answer 2

Answer:

C2H4 burns as follows,

C2H4 + 3O2 ⇄ 2CO2+ 2H2O

To burn 26 g of C2H4, 96 g of oxygen is required

∴ To burn 14 g of C2H4, 96/26 x 14= 51.7 g of oxygen is required
