Ethylene (c2h4) burns in oxygen to produce carbon dioxide and water. what is the correct form of the balanced chemical equation that describes this reaction?

The answer to your question is            C₂H₄  +  3O₂    ⇒    2CO₂   +  2H₂O

Explanation:

Data

Ethylene = C₂H₄

Oxygen = O₂

Carbon dioxide = CO₂

Water = H₂O

Reaction

                          C₂H₄  +  O₂    ⇒    CO₂   +  H₂O

                     Reactant       Element       Product

                           2              Carbon              1

                           4               Hydrogen         2

                           2               Oxygen             3

This reaction is unbalanced

                           C₂H₄  +  3O₂    ⇒    2CO₂   +  2H₂O

                     Reactant       Element       Product

                           2              Carbon              2

                           4               Hydrogen         4

                           2               Oxygen             6

Now, the reaction is balanced

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
