Let us consider the following reaction $\mathrm{A}+2\mathrm{B}\to \mathrm{C}+\mathrm{D}. \mathrm{if} \frac{{\mathrm{W}}_{\mathrm{A}}}{{\mathrm{W}}_{\mathrm{B}}}=0.5$ which of the following are true. (MA and MB are the molecular wt. and ${\mathrm{n}}_{\mathrm{A}} \& {\mathrm{n}}_{\mathrm{B}}$ are the moles

if ${\mathrm{M}}_{\mathrm{A}}={\mathrm{M}}_{\mathrm{B}}$ then no reactants will be left unused after the completion of the reaction

If ${\mathrm{M}}_{\mathrm{B}}>{\mathrm{M}}_{\mathrm{A}}$ then B will be the limiting reactant

If  ${\mathrm{M}}_{\mathrm{A}}>{\mathrm{M}}_{\mathrm{B}}$ then A will be the limiting reactant

If $\frac{{\mathrm{n}}_{\mathrm{A}}}{{\mathrm{n}}_{\mathrm{B}}}=\frac{2}{3}$ then B will be the limiting reactant
