Question

PLEASE ANSWER ASAP.How does the law of conservation of mass apply to this reaction: C2H4 + 3O2 → 2H2O + 2CO2 ?


Only the oxygen needs to be balanced. There are equal numbers of hydrogen and carbon.


The equation needs to be balanced. There are fewer oxygen atoms in the equation than hydrogen or carbon.


The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.


Each element needs to be balanced.

Answer 1

Answer:

C)The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.

Explanation:

I just took the test

Answer 2

The law of conservation of mass applies to the reaction since the equation is balanced.

The correct answer to the question is the 3rd Option. The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.

• The law of conservation of matter states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

• The above statement implies that chemical equation needs to be balanced otherwise, matter will be created or destroyed.

Considering the equation from the question:

C₂H₄ + 3O₂ → 2H₂O + 2CO₂

The above equation is balanced. This simply means that the law of conservation of matter has already been applied.

Thus, the correct answer to the question is the 3rd Option. The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.
