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?

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
