Upon mixing equal volumes of aqueous solutions of $0.1 \, M \, HCl$ and $0.2 \, M \, H_2SO_4$,the concentration of $H^{+}$ in the resulting solution is $.... \, mol / L$.

$A$ sample of $NaClO_3$ is converted by heat to $NaCl$ with a loss of $0.16 \ g$ of oxygen. The residue is dissolved in water and precipitated as $AgCl$. The mass of $AgCl$ (in $g$) obtained will be (Given: Molar mass of $AgCl = 143.5 \ g \ mol^{-1}$)

For a reaction,$N_2O_{5(g)} \rightarrow 2NO_{2(g)} + \frac{1}{2}O_{2(g)}$ in a constant volume container,no products were present initially. The final pressure of the system when $50\%$ of the reaction is completed is:

How many grams of iron are theoretically produced by the reduction of $1 \ kg$ of $Fe_2O_3$?

To neutralise $20 \, mL$ of $M/10$ sodium hydroxide,the volume of $M/20$ hydrochloric acid required is .............. $mL$

What volume of $0.8 \ M$ solution contains $0.1 \ mole$ of the solute? (in $mL$)
