A student wishes to determine the standard reduction potential of an unknown metal electrode in a half-cell. They set up an electrochemical cell using a known standard hydrogen electrode (SHE) as the reference electrode and the unknown metal electrode as the working electrode. A voltmeter is used to measure the potential difference between the two electrodes. The reading is +0.45 V. What is the standard reduction potential of the unknown metal electrode in volts?

A chemistry student needs to calculate the heat of hydration for the reaction between anhydrous magnesium chloride (MgCl2) and water (H2O) using the following data: the enthalpy change for the dissolution of anhydrous magnesium chloride in water is -63.3 kJ/mol, and the enthalpy change for the hydration of magnesium ions (Mg2+) and chloride ions (Cl-) is -192 kJ/mol and -131 kJ/mol, respectively. Calculate the overall heat of hydration (in kJ/mol) for the reaction: MgCl2(s) + 6H2O(l) → MgCl2.6H2O(s)
