Equal masses of ethane $(C_2H_6)$ and hydrogen $(H_2)$ are mixed in an empty container at $298 \ K$. The fraction of total pressure exerted by hydrogen is:

The volumes of two $HCl$ solutions $A$ (Normality $= 0.5 \ N$) and $B$ (Normality $= 0.1 \ N$) to be mixed for preparing $2 \ L$ of $0.2 \ N \ HCl$ are:

If a rocket runs on a fuel $(C_{15}H_{30})$ and liquid oxygen,the weight of oxygen required and $CO_{2}$ released for every litre of fuel respectively are: (Given: density of the fuel is $0.756 \ g/mL$)

What volume of dioxygen is required for complete combustion of $2 \, \text{volumes}$ of acetylene gas at $NTP$?

The weight of $H_2C_2O_4 \cdot 2H_2O$ required to prepare $500 \ mL$ of $0.2 \ N$ solution is .......... $g$.

If $100 \ mL$ of $1 \ N$ sulphuric acid were mixed with $100 \ mL$ of $1 \ M$ sodium hydroxide,the solution will be
