Cufka falcelinta kiimikada: iyadoo la isticmaalayo moles

In a chemical reaction, the atoms in reactants are rearranged and are the same atoms that are in the products. Chemical equations are most correctly interpreted in terms of molar ratios (i.e. 1 mole of A reacts with 2 moles of B). The molar ratios of the substances in a chemical reaction is known as stoichiometry, which means ‘measuring elements’. The stoichiometry of a reaction is shown by coefficients in a balanced equation. These molar relationships don't change. The moles of substance in a reaction can be determined using: mass(g) = Mr × moles (& the stoichiometry of reaction).
