Determine the standard enthalpy of formation for hydrogen chloride gas using the following data:H2(g) + Cl2(g) → 2HCl(g) ΔH = -184.6 kJ/molH2(g) + 1/2O2(g) → H2O(l) ΔH = -285.8 kJ/mol2HCl(g) + O2(g) → 2ClO(g) + H2O(l) ΔH = -518.2 kJ/mol Note: The standard enthalpy of formation for a compound is the change in enthalpy that occurs when one mole of the compound is formed from its constituent elements, with all substances in their standard state at a given temperature (usually 25°C) and pressure (usually 1 atm).

A student wants to electroplate a nickel wire with copper. The student has 1 g of copper sulfate and a 2 M solution of sulfuric acid. The wire has a surface area of 3 cm², and the desired copper thickness on the wire is 0.025 cm. How long should the student electroplate the wire with a current of 1.5 A to achieve the desired thickness of copper? Calculate the current density in the electrochemical cell.
