Magnesium burning Chlorine to give Magnesium chloride, ${\mathrm{MgCl}}_2$. In an experiment, $24 \mathrm{g}$ of Magnesium was found to react with $71 \mathrm{g}$ of Chlorine. How much Magnesium chloride was obtained in the experiment?

Magnesium burning Chlorine to give Magnesium chloride, ${\mathrm{MgCl}}_2$. In an experiment, $24 \mathrm{g}$ of Magnesium was found to react with $71 \mathrm{g}$ of Chlorine. How much of Chlorine will react with $12 \mathrm{g}$ of Magnesium?

Magnesium burning Chlorine to give Magnesium chloride, ${\mathrm{MgCl}}_2$. In an experiment, $24 \mathrm{g}$ of Magnesium was found to react with reacts with $71 \mathrm{g}$ of Chlorine. How much Magnesium chloride will be formed a certain amount of Chlorine reacts with $12 \mathrm{g}$ of Magnesium?

Methane has the formula ${\mathrm{CH}}_4$. Work out the $\%$ of Carbon and Hydrogen in it. $\left({\mathrm{A}}_{\mathrm{r}}; \mathrm{C}=12; \mathrm{H}=1\right)$

In an experiment, a sample of Lead $\left(\mathrm{II}\right)$ bromide was made. It weighed $15 \mathrm{g}$. But the sample was found to be impure. In fact, it contained only $13.5 \mathrm{g}$ of Lead $\left(\mathrm{II}\right)$ bromide. Calculate the percentage purity of the sample.
