Q.13Carbon reacts with chlorine to form CCl 36 gm of carbon was mixed with 142 g of Cl, Calculatomass of CCI, produced and the remaining mass of reactant |
|
Answer» Reaction for the above is⇒ C + 2Cl₂ ----------→ CCl₄ In this Reaction, Chlorine is the limiting reactant. We can prove that. 12 g of the carbon reacts with 4× 35.5 g of the Chlorine.∴ 1 g of the Carbon reacts with the 142/12 g of the chlorine.∴ 36 g of the Carbon reacts with the 426 g of the Chlorine. Since, the mas of the chlorine given is less than the chlorine required.∴ Chlorine is the limiting reactant.Thus, whole reaction will be controlled by the Chlorine. ∵ 4× 35.5 g of the Chlorine reacts with the 12 g of the Carbon.∴ 1 g of the Chlorine reacts with the 12/142 g of the Carbon.∴ 142 g of the Chlorine reacts with the 12 g of the Carbon. Now, the mass of the carbon reacts is less than the mass of the Carbon present, therefore, it is in excess amount. Now,∵ 2× 35.5 g of the Chlorine produces 154 g of the CCl₄.∴ 1 g of the chlorine produces 154/142 g of the CCl₄.∴ 142 g of the CCl₄ produces 154 g of the CCl₄. Mass of the CCl₄ Produced is 154 g.Mass of the Carbon left = 36 - 12= 24 g.Mass of the chlorine left = 0 g[Since, it is completely used up in the reaction]. |
