Post Utme Oau 2022 Chemistry Question 34
Practice objective / multiple choice question 34 from the 2022 Post Utme Oau Chemistry examination.
Calculate the s\tandard enthalpy change (ΔH°) for the reaction: 2Al(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2(g). Given that the s\tandard enthalpy of formation (ΔHf°) for AlCl3(s) is -1675.7 kJ/mol, and the s\tandard enthalpy of formation for H2(g) is 0 kJ/mol. The s\tandard enthalpy of formation for Al(s) is 0 kJ/mol, and the s\tandard enthalpy of formation for HCl(aq) is -167.2 kJ/mol.
