What is a balancing equations of chemical reactions?

Answer 1

coefficients

Answer 2

A balanced equation contains equal numbers of each elements on the reactant and the product side of the equation.

A balanced chemical equation contains equal numbers of each element on the reactant and on the product side of the equation

2H2 + O2 → 2H2O
A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example:

2H20 --> 2H2 + O2

This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction).

Technically the equation wouldn't work in real life if it weren't correctly balanced.
Since there is nothing "following", the answer must be NONE OF THEM.

Answer 3

A balanced chemical equation demonstrates the law of conservation of mass, which requires the same number of atoms of each element to appear both sides of a chemical equation.

A coefficient is a number that is placed in front of a chemical formula in a balanced equation to show how many units of the substance are involved in the reaction.

It is very important to remember that the only way to balance a chemical equation is to add coefficients.

Answer 4

Making both sides of the equation (reactants and products) have the same number of elements. example, making sure the products have 2 hydrogen atoms because the reactants' side does.

Answer 5

There are two sides of a chemical reaction, namely reactants and products. As there is neither creation nor destruction in atoms or charge, both of these facts should be balanced.

Answer 6

A balanced chemical equation establishes the proper relationship between reactants and products.

Answer 7

When in a chemical equation the number of atoms for the reactants and products is the same the equation is correctly balanced.
