The metals that are employed in the battery industries are A. Fe, B. Mn, C. Ni, D. Cr, E. Cd. Choose the correct answer from the options given below:

Identify the factor from the following that does not affect electrolytic conductance of a solution.

Integrated rate law equation for a first order gas phase reaction is given by (where $$P_i$$ is initial pressure and $$P_t$$ is total pressure at time $$t$$)

Give below are two statements: 

Statement-I: Noble gases have very high boiling points. 

Statement-II: Noble gases are monoatomic gases. They are held together by strong dispersion forces. Because of this they are liquefied at very low temperature. Hence, they have very high boiling points. 

In the light of the above statements, choose the correct answer from the options given below:

Identify correct statements from below:

A. The chromate ion is square planar. 

B. Dichromates are generally prepared from chromates. 

C. The green manganate ion is diamagnetic. 

D. Dark green coloured $$K_2MnO_4$$ disproportionates in a neutral or acidic medium to give permanganate.

E. With increasing oxidation number of transition metal, ionic character of the oxides decreases.

Choose the correct answer from the options given below:

The correct statements from the following are:

A. The strength of anionic ligands can be explained by crystal field theory.

B. Valence bond theory does not give a quantitative interpretation of kinetic stability of coordination compounds. 

C. The hybridization involved in formation of $$[Ni(CN)_4]^{2-}$$ complex is $$dsp^2$$. 

D. The number of possible isomer(s) of cis-$$[PtCl_2(en)_2]^{2+}$$ is one. 

Choose the correct answer from the options given below:

Given below are two statements: 

Assertion A: $$pK_a$$ value of phenol is $$10.0$$ while that of ethanol is $$15.9$$. 

Reason R: Ethanol is stronger acid than phenol.

In the light of the above statements, choose the correct answer from the options given below:

Given below are two statements:

Assertion A: Alcohols react both as nucleophiles and electrophiles. 

Reason R: Alcohols react with active metals such as sodium, potassium and aluminum to yield corresponding alkoxides and liberate hydrogen. 

In the light of the above statements, choose the correct answer from the options given below:

The compound that is white in color is

Match List I with List II: 

Choose the correct answer from the options given below:
