A voltaic cell is constructed that uses the following reaction and operates at 298 K. (Ered Ni+2 is -0.277) Zn(s) + Ni2+(aq) Zn2+(aq) + Ni(s) (a) What is the emf of this cell under standard conditions?
Gives what happens at low pH for aluminum hydroxide. A) Al(OH)3 precipitates B) Al precipitates C) Al dissolves D) Al(H2O)63+ dissolves
A second order reaction is found to have an activation energy of 20 kj/mol at 298K. At what temperature would this reaction need to occur at to proceed twice as fast
Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP.
A 20 degrees Celsius, the solubility of potassium nitrate is 30g in 100g of water. A 35 gram solution of potassium nitrate in water was determined to contain 10 grams of KNO3.
