Calculate the kinetic energy of 0.2 g of `H_2` at `27^@C`.

The kinetic energy of 1g for hydrogen a 27^@C will be

Calculate the oxidation number of C in C2H6

Calculate the volume occupied by 4.4 g of CO_2 at 27^@C and under a pressure of 0.5 atmosphere.

Calculate the pH of 0.2 M H_2SO_4 .

The entropies of H_(2) (g) and H (g) are 130.6 and 114.6 J mol^(-1)K^(-1) respectively at 298 K. Using the data given below calculate the bond energy of H_(2) (in kJ/mol) : H_(2)(g)rarr2H(g),DeltaG^(@)=406.6kJ

Calculate the work done (in J) when 4.5 g of H_(2)O_(2) reacts against a pressure of 1.0 atm at 25^(@)C 2H_(2)O_(2)(l)rarr O_(2)(g) +2H_(2)O(l)
