The chloride of a metal has the formula $MCl_3$. The formula of its phosphate will be

What is the volume of $CO_2$ in liters produced at $STP$ by the complete decomposition of $9.85 \ g$ of $BaCO_3$? (Atomic mass of $Ba = 137$,$C = 12$,$O = 16$)

The masses of carbon dioxide and water (in $g$) respectively formed during complete combustion of $10 \ g$ of glucose at $STP$ are

$23 \ g$ of sodium will react with methyl alcohol to give

Equal volumes of $0.1 \ M$ $AgNO_3$ and $0.2 \ M$ $NaCl$ are mixed. The concentration of $NO_3^-$ ion in the mixture will be ............ $M$.

Calculate the volume of $CO_2$ at $NTP$ that can be obtained by heating $200 \ g$ of $80 \%$ pure $CaCO_{3(s)}$.
