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.

2H2 + O2 ---->2H2O is balanced for the following reasons. Hydrogen and oxygen exist as H2 and O2 and not H and O. The product is water with a formula of H2O. To get balance the number of atoms of reactants and the number of atoms of products must be equal. They are in the balanced equation above. For these reasons the equation is balanced.
The coefficients in a chemical equation represent the amount of moles of each substance involved in the reaction. On a smaller level, it also represents the amount of particles that have to collide or are produced in the reaction. Consider the following example: CH4(g) + 2O2(g) (arrow) 2H2O(l) + CO2(g) The coefficent behind oxygen in the reactants means that 2 molecules of oxygen have to collide with 1 molecules of methane to react. The coefficients in the products mean that this reaction produces 2 molecules of water and 1 molecule of carbon dioxide.
2K + 2H2O --> 2KOH + H2 The balanced equation shows that there is a 2 in front of water.
The definition of a balanced chemical equation is one with the same number of atoms on each side of the equation with each molecule electrically neutral. If the reactants and products apparently only switch anions with no extra product such as molecular gas or water, you could end up with an equal number of molecules on each side of the equation.
Let the fourmula for the hydrous copper sulphate be CuSO4XH20 where X represents the number of water molecules write a balanced equation for the heating of the blue copper sulphate crystals?
a balance equation when it come to bio is that the input be exactly equal to the output. this will make the organism balanced with the environment it is in like a regulator fish in water. input=output. in chemistry: A balanced equation is used for chemical reactions. When the number of moles of reactants is equal to the number of moles of products, the equation is considered balanced. Search wikipedia for chemical equation for a step by step tutorial on how to balance chemical reaction equations.

The balanced equation for the reaction between calcium hydroxide and hydrochloric acid is: Ca(OH)2 + 2HCl → CaCl2 + 2H2O In this reaction, calcium hydroxide (Ca(OH)2) reacts with hydrochloric acid (HCl) to produce calcium chloride (CaCl2) and water (H2O). The equation is balanced with 1 molecule of calcium hydroxide reacting with 2 molecules of hydrochloric acid to produce 1 molecule of calcium chloride and 2 molecules of water.

Phosphine is not very soluble in water compared to nonpolar substances. If you were to write a balanced equation for the reaction of PH3 with water, it would be an equilibrium reaction.
2K + 2H2O --> 2KOH + H2 The balanced equation shows that there is a 2 in front of water.
Chromium don't react with water.
O + h2 = h2o
