The normality of `0.3 M` phosphorous acid `(H_(3) PO_(3))` isA. (a)0.1

1.	The normality of `0.3 M` phosphorous acid `(H_(3) PO_(3))` isA. (a)0.1B. (b)0.9C. (c )0.3D. (d)0.6
Answer» Correct Answer - D `H_(3)PO_(3)` is a dibasic acid and thus its molecular weight `=2xx "equivalent" wt`. `:. 1 M=2N` Hence, `0.3 M=2xx0.3=0.6 N`

(b)If both assertion and reason are true and the reason is not the correct explanation of the assertion.C. (c )If assertion is true but reason is false.D. (d)If assertion is false but reason is true.
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.
