In the following reaction:

\(\mathrm{HCO}_{3}^{-}+\mathrm{H}_{2} \mathrm{O} \rightleftharpoons \mathrm{CO}_{3}^{2-}+\mathrm{H}_{3} \mathrm{O}^{+}\)

Which two substances are Bronsted base?

\(0 \mathrm{~L}\) each of \(\mathrm{CH}_{4}\) (g) at \(1.00 \mathrm{~atm}\), and \(\mathrm{O}_{2}\) (g) at \(4.00\) atm, at \(300^{\circ} \mathrm{C}\) are taken and allowed to react by initiating the reaction with the help of a spark.

\(\mathrm{CH}_{4}(g)+2 \mathrm{O}_{2}(g) \rightarrow \mathrm{CO}_{2}(g)+2 \mathrm{H}_{2} \mathrm{O}(g), \mathrm{H}=-802 \mathrm{~kJ}\)

Mass of \(\mathrm{CO}_{2}(\mathrm{~g})\) produced in the reaction is:

The order of stability of the following carbocations is :

\(\mathrm{CH}_2=\mathrm{CH}-\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_2 ; \mathrm{CH}_3-\mathrm{CH}_2-\stackrel{\oplus}{\mathrm{CH}}{ }_2\)
