306666 Read the Statement -A and Statement -B carefully to mark the correct options given below :
Statement A :
Law of conservation of mass hold good for nuclear reactions.
Statement B :
This law states that mass can neither be created nor be destroyed in a chemical reaction.

306667 Assertion :
The balancing of chemical equations is based on law of conservation of mass.
Reason :
Total mass of reactants is equal to total mass of a products.

306668 3 g of a hydrocarbon on combustion in excess of oxygen produces 8.8 g of \({\rm{C}}{{\rm{O}}_{\rm{2}}}\) and 5.4 g of \({{\rm{H}}_{\rm{2}}}{\rm{O}}\). The data illustrates the law of

306670 \(\mathrm{SO}_{2}\) gas was prepared by (i) burning sulphur in oxygen, (ii) reacting sodium sulphite with dilute \(\mathrm{H}_{2} \mathrm{SO}_{4}\) and (iii) heating copper with conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\). It was found that in each case sulphur and oxygen combined in the ratio of \(1: 1\). The data illustrates the law of
