Assertion: Laboratory reagents are usually made up to a specific molarity rather than a given molality. Reason: The volume of a liquid is more easily measured than its mass.A. (a)If both assertion and reason are true and the reason is the correct explanation of the assertion.B. (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.
Assertion: On heating, a solid usually change to a liquid and the liquid on further heating change to the gaseous state. Reason : Arrangement of constituent particles is different in solid, liquid and gaseous state.A. If both assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true but reason is not correct explanation of assertion.C. If assertion is true but reason is false.D. If both assertion and reason are false.

Assertion : 1 amu equals to `1.66xx10^(-24)` g. Reason : `1.66xx10^(-24)g` equals to `1/12` th of mass of a `C^(12)` atom.A. If both assertion and reason are true and the reason is the correct explanation of the assertion.B. If both assertion and reason are true but reason is not the correct explanation of the assertion.C. If assertion is true but reason is false.D. If the assertion and reason both are false.
Assertion: The average mass of one Mg atom is `24.305 amu`, which is not actual mass of one Mg atom. Reason: Three isotopes, `24 Mg, 25 Mg and 26 Mg`, of Mg are found in nature.A. (a)If both assertion and reason are true and the reason is the correct explanation of the assertion.B. (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 reaction does not shwo oxidizing behaviour?A. `CaF_(2)+H_(2)SO_(4) rarr CaSO_(4)+2HF`B. `Cu+2H_(2)SO_(4) rarr CuSO_(4)+SO_(2)+2H_(2)O`C. `2S+2H_(2)SO_(4) rarr 2SO_(2) +2H_(2)O`D. `C+2H_(2)SO_(4) rarr CO_(2)+2SO_(2)+2H_(2)O`
Bleaching powder and bleach solution are produced on a large scale and used in several hous-hold products. The effectiveness of bleach solution id often measured by iodometry. `25 mL` of household bleach solution was mixed with `30 mL` of `0.50 M KI` and `10 mL` of `4N` acetic acid. In the titration of the liberated iodine, `48 mL` of `0.25 N Na_(2)S_(2)O_(3)` was used to reach the end point. The molarity of the household bleach solution is :A. 0.48 MB. 0.96 MC. 0.24 MD. 0.024 M
