carlos is making phosphorus trichloride using the equation below. 2p + 3cl₂ → _pcl₃. what coefficient of pcl₃ would show that the law of the conservation of mass is represented in the chemical equation?\n4\n3\n2\n1
Answer
Explanation:
Step1: Count phosphorus atoms on left - hand side
There are 2 phosphorus (P) atoms on the left - hand side of the equation $2P + 3Cl_2\rightarrow_PCl_3$.
Step2: Determine coefficient for $PCl_3$ for P - atom balance
To balance the phosphorus atoms, since there are 2 P atoms on the left, the coefficient of $PCl_3$ must be 2 so that there are also 2 P atoms on the right - hand side.
