In a balanced equation, the number of each type of atom on the reactant side the number of each type of atom on the product side.

Equal

In balanced equation, the number of each type of atom on reactant side are equal to the number of each type of atom on product side.

Explanation:

Example:

Consider the example of neutralization reaction.

Hydrochloric acid when react with the sodium hydroxide, a salt sodium chloride and water are formed.

Chemical equation:

HCl + NaOH → NaCl + H₂O

When an acid react with base it form the salt and  water. The reaction is also called neutralization reaction because both neutralize each other.

In neutralization reaction equal amount of acid and base react to neutralize each other and equal amount of water and salt are formed. We can see that two hydrogen atoms, one chlorine atom, one oxygen atom and one sodium atom are present on left and also on right side.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
