Why

Why do we need to follow the law of conservation of mass when dealing with chemical reactions?

We need the law of conservation of mass to balance all chemical equation. Without it the reaction just would not make sense. Without it, it would mean that matter just disappeared or appeared out of nowhere.

WE need the law of conservation of mass to balance all chemical equation. Matter just can'tcome out of nowhere and this law proves it.

We need the law of conservation of mass to balance all cheical equation. The reaction wouldn't make sense without it. If we didn't have it, it would mean that matter would just disappear or appear out of nowhere.

It is used when we are balancing chemical equations. It brings th equation together otherwise it wouldn't make sense really. It is needed to put reactions together.

The reason we need to follow that law of conservation of mass is because we need that to balance chemical equations. if not for that there would be a way to balance anything.

Its a law and its for balancing all chemical equations. The equations wouldn't be right and matter wouldn't be matter anymore. This is a sad deal.

The law of conservation is very important in dealing with chemical equations. It is used to balance all chemical equations. I wouldn't make sense without it.

We should follow the law of conservation of mass to balance all of the chemical equations. If you didn't balance, they wouldn't make sense. If we didn't have the law of conservation it would mean it would disappear or appear out of nowhere.

We need to use to find and balance chemical equations. It states that matter has a reason to appear. It just aint there.

mike goetz said...

This law states that matter can neither be created or destroied only change form. That and a law is absolute

we need to follow it because if we dont the mass of an object will be off. The equation wont be balanced and people wont be able to balance it. It basically a thing that needs to be done.

We need the law of conservation of mass, because when we balance equations, it cant just come from nowhere.
