Al + FeCl3 → Fe + AlCl3 1. 3.6 grams of aluminum are put in a container with 9.8 grams of FeCl3 How many grams of iron can be produced? Which is the limiting reactant?

N2 + H2 → NH3
2. 3.5 grams of nitrogen is allowed to react with 3.5 grams of hydrogen. How many grams of ammonia (NH3) can be produced? What is the limiting reactant?

For the following, determine the type of reaction and then give products.

Consider the heating curve of h2o and line segments a, b, and c. several changes are taking place at a, b, and c. all but one would be an appropriate description as e move through segments a, b and then c.

Achemist at a pharmaceutical company is measuring equilibrium constants for reactions in which drug candidate molecules bind to a protein involved in cancer. the drug molecules bind the protein in a 1: 1 ratio to form a drug-protein complex. the protein concentration in aqueous solution at 25 ˚c is 1.74 x10-6 m . drug a is introduced into the protein solution at an initial concentration of 2.00 x10-6m. drug b is introduced into a separate, identical protein solution at an initial concentration of 2.00 x10-6m. at equilibrium, the drug a-protein solution has an a-protein complex concentration of 1.00 x10-6m, and the drug b solution has a b-protein complex concentration of 1.40 x10-6m.a. calculate the kc value for the a-protein binding reaction.b. calculate the kc value for the b-protein binding reaction.c. assuming that the drug that binds more strongly will be more effective, which drug is the better choice for further research?
