$2.76 \, g$ of silver carbonate on being strongly heated yields a residue weighing $..........$ $g$.

How many moles of $H_2O$ (per mole of $Cl_2$ evolved) will be formed when $KMnO_4$ is added to $HCl$ solution?

When $100 \, mL$ of $1 \, N \, NaOH$ solution and $10 \, mL$ of $10 \, N$ sulphuric acid solution are mixed together,the resulting solution will be:

What will be the volume of $4.4 \ g$ of $CO_2$ at $STP$ in liters?

What is the volume of $22.4 \, L$ of water vapor at $NTP$ when it is condensed into liquid water?

For the given series of reactions:
$NH_{3(g)} + O_{2(g)} \rightarrow NO_{(g)} + H_2O_{(l)}$
$NO_{(g)} + O_{2(g)} \rightarrow NO_{2(g)}$
To obtain the maximum mass of $NO_2$ from a given mass of a mixture of $NH_3$ and $O_2$,the ratio of the mass of $NH_3$ to $O_2$ should be:
