Question 1

Balancing Half-equations in ALKALINE Conditions

Answer 1

Question 2

Metal-Metal Ion Equilibria

Answer 2

Question 3

difference in potential between metal and solution - magnesium and copper

Answer 3

Unfortunately, that voltage is impossible to measure and is sometimes called an absolute potential.

Question 13

Question type 1: What is the voltage (emf) for a given cell? What is the cell reaction? What are the + and — electrodes? Which way do electrons flow?

Answer 13

Question 14

Question type 3: Two of the same half cell but with different concentrations

Answer 14

Question 15

Question type 4: Using Standard Electrode Potentials to Predict if Chemical Reactions are Spontaneous (feasible)

Answer 15

Question 16

question type 5:-Sequential Oxidation and Reduction

Answer 16

Question 17

Question type 6: Predicting the effects of changing
concentration on the emf of a cell — quick method

Answer 17

Increasing the concentration of Fe? shifts the position of equilibrium of the overall equation to the right. Therefore, Ecel will increase
