Iwill give brainiest! 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.

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

We are given;

C₂H₄ + 3O₂ → 2H₂O + 2CO₂

We need to ask ourselves the following questions;

Is the equation balanced?

What is the law of conservation of mass?

What makes the equation obey the law of conservation of mass?

indium, and thallium have three electrons i think

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
