Carlos is making phosphorous trichloride using the equation below. he adds 15 g of phosphorus. 2p +3cl2 → 2pcl3 how much chlorine would be found in the product

The equation of the reaction for the production of the phosphorus trichloride is : 2P + 3CI2 = 2PCI3. Carlos added 15g of phosphorus, but there are two molecules of phosphorus in the chemical reaction, this implies that, there are 7.5g of phosphorus for each phosphorus atom, therefore, we are going to multiply both sides of the chemical reaction by 7.5. 2 * 7.5 = 15. Then 15 * 3 = 45. Thus, 45g of chlorine will be found in the product.

The answer is a) carbon-12
