Which amongst the following DOES NOT hold good for a balanced chemical equation?
1. Obeys laws of conservation of energy and mass
2. Has equal number of atoms of each element on both sides of the equation
3. Mass of reactants is equal to mass of products
4. Has equal number of charges on both sides of the equation

Actually all the four points should hold good for a balanced chemical equation.
1. The law of conservation of energy states that in all chemical reactions, energy is neither created nor destroyed. Similarly the law of conservation of mass states that in all chemical reactions, matter is neither created nor destroyed.
The law of conservation of mass which states that during any chemical reaction, the mass of the products is always equal to the mass of the reactants. The law of conservation of energy which states that during any chemical reaction, the energy utilized is converted into another form.
2. The amount of atoms on the LHS of the reaction must equal the amount of atoms on the RHS.
3. Mass of reactants is equal to mass of products – again The law of conservation of mass.
4. We balance charge in exactly the same way that we balance atoms: the amount of charge on the LHS of the reaction must equal the amount of charge on the RHS. Charge is important. Charge is fundamental. Charge strictly obeys a local conservation law.
