1.	5 mL of N HCl, 20 mL of N/2 `H_(2)SO_(4)` and 30 mL of `N/3HNO_(3)` are mixed together and volume made to 1L. The normality of resulting solution isA. 0.45B. 0.025C. 0.9D. 0.05
Answer» Normally equtaion is `N_(1)V_(1)+N_(2)V_(2)+N_(3)V_(3)=N_(4)(V_(1)+V_(2)+V_(3))` or `1xx5+20xx(1)/(2)+30xx(1)/(3)=N_(4)(5+20+30)` `(HCI) (H_(2)SO_(4)) (HNO_(3))` `therefore` Resulting normality `(N_(4))=(25)/(55)=0.45N`.

Which of the following statements is correct about the reaction given below:- `4Fe(s)+3O_(2)(g)rarr2Fe_(2)O_(3)(g)`A. Total mass of iron and oxygen in reactants = total mass of iron and oxygen in product, therefore, it follows law of conservation of mass.B. Total mass of reactant = total mass of product, therefore, law of multiple proportions is followed.C. Amount of `Fe_2O_3` can be increased by taking any one of the reactants (iron or oxygen ) in axcess.D. Amount of `Fe_2O_3` produced will decreased if the amount of any one of the reactants (iron or oxygen ) is taken in excess.
