Question

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

Answer 1

I think it is 66.4

Step-by-step explanation:

I was taking the Exam and this question popped up on it I am not sure if I got it right but I got a good grade on it since it was a online exam I didn't get to check the answers.

Answer 2

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.
