By having the same numbers of atoms of each kind of element present in the equation in the written numbers (coefficient multiplied by subscript) of each kind of element on both sides of the equation.

What is understood if no coefficient is written before a formula in a chemical equation?
if no number is written following a chemical symbol in a chemical formula, it is understood the number of atoms of that element is one
What is a balanced chemical equation why should the chemical equation be balanced?
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.
How does chemical equations show a conservation of mass?
A properly written chemical equation will always show the same number of atoms of each elemental on each side, showing that no atoms are created or destroyed in the chemical reaction.
What law states that the number of atoms on the right of a chemical equation is equal to the number of atoms on the left of the chemical equation called?
This is the law of mass conservation.
Which number in a chemical equation shows you the number of atoms?
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.

This is the law of mass conservation.
What is the full balanced chemical equation?
Any chemical equation where atoms and energy are equal on each side.
What do you notice about the number of atoms on each side of a chemical equation?
That the number of atoms on the left side of the equation must be the same number of atoms that are on the right side of the equation.
Which number in a chemical equation shows you the number of atoms?
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.
Does a chemical equation show the number of atoms lost during a chemical reaction?
no
What do you mean by balanced chemical equation?
A balanced chemical equation is one where the number of the same atoms on both sides are equal. A balanced chemial equation is important because during a chemical reaction, there is rearrangement of atoms only and no new atoms are added. To understand the concept of a balanced chemical equation, first consider an unbalanced chemical equation between magnesium and oxygen to form magnesium oxide. Unbalanced chemical equation: Mg(s) + O2(g) --> MgO(s) Initially, this equation is unbalanced because if we count the number of the oxygen atoms on both sides, the number are unequal. There are two oxygen atoms on the left side but only one on the right side. A balanced chemical equation is one where the number of all of the same atoms on both side are equal. We can balance chemical equations by adding numbers to the coefficient of the chemicals that are involved in the reaction. Balanced chemical equation: 2Mg(s) + O2(g) --> 2MgO(s) This equation is now balanced because if we count the number of the same atoms on both side, they are equal. There are two magnesium atoms and two oxygen atoms on both sides of the equation.
