Why do we balance chemical equations?

[Madelyn Cearlock]

For the question that asks why do we balance chemical equations, what was the exact answer that was desired? Thank you!

To show the conservation of mass.

[Christopher Tran 1J]

Balancing chemical equations makes sure that the number of moles of reactants and products are the same, and therefore agree with the law of conservation of mass.

[Marwan Masri 3B]

if the number of atoms of each element is not the same on both the reactants and the products side, the law of conservation of mass would be violated.

I put to conserve the law of conservation of mass and I got it right.

[Karishma_1G]

I said that we balance them because of the law of conservation of mass which states that matter cannot be created nor destroyed.

[Xinyi Zeng 4C]

I wrote "to make sure the law of conservation of mass is obeyed as there should be equal number of atoms of the same element on both sides of the reaction equation", and I got full credit for it. I think the most essential part of the answer is "the law of conservation of mass".

We balance chemical equations due to the law of conservation of mass, which states that mass can neither be created or destroyed. Therefore, in a chemical reaction, the total mass of the reactants must be equal to the total mass of the products. Balancing equations accounts for the total mass of the reactants and the total mass of the products.

Because of the law of conservation of mass.

We want to make sure not break the law of conservation of mass. It is important to balance on each side, the products and the reactants.

[Brian Kwak 1D]

It is because of the concept of conservation of mass which states that in an isolated system mass can not be created nor destroyed by chemical reactions or physical transformations. Since the chemical reaction can not destroy or create mass the number of elements from the reactants must equal the number of elements that are produced.

To show the conservation of mass. Also my TA said not to assume every chemical equation we get on the exam will be balanced. He said to verify everytime we are presented with an equation to check ourselves that it is balanced.

[Karolina herrera1F]

This would be to show the conservation of mass a chemical equation must have an equal number of each type of atoms on both sides of the reaction arrow.

[Joanne Lee 1J]

According to the law of conservation of mass, during a chemical reaction, mass is neither created or destroyed so the equation must be balanced in order to follow this law.
