Methane and ethylene

A mixture of methane and ethylene in the volume ratio x : y has a total volume of 30 ml . On complete combustion it gave 40 ml of CO_(2) . If the ratio had been y :x , instead of x : y , what volume of CO_(2) could have been obtained ?

A mixtures of methane and ethylene in the volume ration x:y has total volume of 30mL. On complete combustion it gave 40mL of CO_(2) . IF the ratio of original mixture is y:x instead of x:y. What volume of CO_(2) would have been produced a combustion?

Dissociation enthalpies of methane, ethane and ethylene are respectively 400, 680 and 540 k cal mol^(-1) . Calculate sigma C-H, sigma C-C and pi C-C bond energies.

CaC_(2) on hydrolysis gives a.Ethane b.Ethylene c.Methane d.Acetylene

The following is (are) endothermic reaction I. combustion of methane. II. Decomposition of water. III. Dehydrogenation of ethane to ethylene IV. Conversion of graphite to diamond

Prepare from methane : Ethylene

Three separate cylinders contain methane, ethylene & acetylene respectively. How will you identify them ?
