From the figure of the electrochemical cell, what is producing the current in the wire connecting the electrodes?
electrons moving from Zn to Cu
cations moving to the anode
anions moving to the cathode
voltage (E
applied to the circuit

Just tested it and the correct answer is A. I hope this helps

he would use the colour black

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.
