Vedclass · Answer

(B) The combustion reaction of carbon is: $C_{(s)} + O_{2(g)} \longrightarrow CO_{2(g)}$From the stoichiometry,$1 \ mol$ of $C$ produces $1 \ mol$ of $CO_{2(g)}$.Molar mass of $C = 12 \ g/mol$.Number of moles of $C = \frac{6 \ g}{12 \ g/mol} = 0.5 \ mol$.Since $1 \ mol$ of $C$ gives $1 \ mol$ of $CO_{2(g)}$,$0.5 \ mol$ of $C$ will produce $0.5 \ mol$ of $CO_{2(g)}$.At $STP$,the molar volume of an ideal gas is $22.4 \ dm^3/mol$.Volume of $CO_{2(g)} = 0.5 \ mol 	imes 22.4 \ dm^3/mol = 11.2 \ dm^3$.

What volume of $CO_{2(g)}$ at $STP$ is obtained by complete combustion of $6 \ g$ carbon (in $dm^3$)?
