A. A spontaneous redox reaction happens between zinc (Zn) and magnesium (Mg) in an electrochemical cell. (5 points) i. Use the reduction potential chart to determine which metal is oxidized and which is reduced. (1 point)

ii. Write the half-reactions for this reaction, indicating the oxidation half-reaction and the reduction half-reaction. (1 point)

iii. Which metal is the anode, and which is the cathode? (1 point)

iv. Calculate the standard potential (voltage) of the cell. (1 point)

v. What kind of electrochemical cell is this? Explain your answer. (1 point)

It conforms what ever surface its in.

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
