Chemical reaction and equation class 10th (Notes)
Chemical reaction Chemical reaction are the process in which a new substance having a new property are formed . Unbalanced chemical equation In unbalanced chemical equation , number of atom of each type in reactant side (LHS) is not equal to the number of atoms in product (LHS). Balanced chemical equation in chemical equation in which the number of all the atoms on LHS and RHS is equal is called balanced chemical equation . Balancing of chemical equation the process of balancing an unbalanced equation is called balancing of chemical equation. Combination reaction Those chemical reaction in which two or more substance combine to form a single substance are called combination reaction . Example Mg+O2→2MgO H2(g)+Cl2(g) →2Hcl(g) Decomposition reaction those reaction in which a single reactant breaks down to give two or more simpler product are called decomposition reaction . CaCO3(s)→CaO(s)+CO2(g) Electrolysis the pro...
