Ozone is manufactured by carrying silent electric discharge using:

Assertion: Group 15 elements are less reactive than Group 16 elements.
Reason: Group 15 elements have a higher ionization energy and a lower electronegativity than Group 16 elements.

When $\mathrm{NF}_3$ undergoes hydrolysis at room temperature, then the product will be:

Which of the following(s) when heated give nitrogen gas?

Which of the following statements is wrong?

Nitric acid whether diluted or concentrated:

Xenon directly combines with:

The substance which does not liberate oxygen on treatment with ozone is

Assertion (A): Noble gases have very high boiling point.
Reason (R): Noble gases have strong dispersion forces hence they liquify at low temperature, hence they have high boiling point.

When a brown compound of $\mathrm{Mn}(\mathrm{A})$ is treated with $\mathrm{HC}{l}$, it gives a gas (B). The gas $(\mathrm{B})$ taken in excess reacts with $\mathrm{NH}_3$ to give an explosive compound $(\mathrm{C})$. The compound $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ are

${I_2}$ dissolves in KI solution due to the formation of

Assertion (A): $\left(\mathrm{NH}_4\right)_2 \mathrm{Cr}_2 \mathrm{O}_7,$ on heating doesn't form any residue.

Reason (R): In $\mathrm{Cr}_2 \mathrm{O}_7^{2-}$ there are six equivalent $\mathrm{Cr}-\mathrm{O}$ bonds.
