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?

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
