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?

An electric kettle uses electrical energy to boil water. energy from the electricity is transferred to the water, heating it up. an electric ice maker also uses electrical energy, but it freezes water to form ice. since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice, what happens to the energy put into the ice maker and the energy released by the water?

The absolute tempeature of a gas is increased four times while maintaining a constant volume. what happens to the pressure of the gas
