Answer:12) In the ball and stick model, one orange ball represents the phosphorus atom and three green balls represent the chlorine atoms connected by the sticks placed between the green and orange to represent the shared electrons between phosphorus and chlorine with chlorine atoms. forming the base of a triangular pyramid while the phosphorus atom is at the top of the pyramid.
13) The scientist will have 6 grams of product as before, but will have 2 grams of unreacted copper atoms due to the large copper to sulfur ratio in this reaction, the ratio is 2:1.
Description:
12) Phosphorus trichloride has a trigonal pyramidal structure and is composed of three chlorine atoms and one phosphorus atom.
In the ball and stick model, an orange ball representing the phosphorus atom and three green balls representing the chlorine atoms are connected by colored sticks to represent the green and orange half of the electrons shared between phosphorus and chlorine with atoms of chlorine. the base of the triangular pyramid and the phosphorus atom is at the top of the pyramid.
13) The reaction between copper and sulfur to form copper sulfide is illustrated in the following equation.
Cu+S ---> CuS
Combine 1 mole of copper with 1 mole of sulfur to get 1 mole of copper sulfide.
molar mass of copper = 64 g/mol; molar mass of sulfur = 32 g/mol, molar mass of copper sulphide = 96 g/mol
Copper/sulfur mass ratio = 63 g/ 34 g = 2
