One mole of calcium phosphide on reaction with excess of water gives

The ammonia $(NH_{3})$ released on quantitative reaction of $0.6 \ g$ urea $(NH_{2}CONH_{2})$ with sodium hydroxide $(NaOH)$ can be neutralized by

If the mixture of $7 \ g$ of $N_2$ and $8 \ g$ of $Ar$ in a cylinder has a total pressure of $27 \ bar$,what is the partial pressure of $N_2$ (in $bar$)? (Atomic mass of $N = 14 \ g \ mol^{-1}$,$Ar = 40 \ g \ mol^{-1}$)

$25 \, mL$ of a decinormal $NaOH$ solution is completely neutralized by $0.16 \, g$ of a dibasic acid. The molecular weight of the dibasic acid is:

For a gaseous reaction $Cl_{2(g)} + PCl_{3(g)} \to PCl_{5(g)}$. If $10 \ mL$ of $Cl_2$ completely react with $PCl_3$,then find out the produced volume of $PCl_5$ in $mL$.

When $5 \, mL$ of $N \, HCl$,$20 \, mL$ of $N/2 \, H_2SO_4$,and $30 \, mL$ of $N/3 \, HNO_3$ are mixed together and the volume is made up to $1 \, L$,the normality of the resulting solution is:
