Al (s) + NаOH (аq) + H₂O (l)→NаAlO₂ (aq) + H₂ (g) The fоllоwing data shоw the standard enthalpy of formation (ΔHf°) for each substance: Substance ΔHf° (kJ/mol) NaOH(aq) −469.15 NaAlO₂(aq) −1133.2 H₂O(l) −285.83 (Note: For elements in their standard states like Al(s) and H₂(g), ΔHf° = 0.) Based on the above information, a. Write and balance the chemical equation for this reaction. b. Using the ΔHf° values given above, calculate the standard enthalpy change (ΔH°) for the balanced reaction. Show all your work. c. Suppose this reaction takes place in a closed bottle with a balloon attached to collect the hydrogen gas.If the reaction releases 15.0 kJ of heat at 1.00 atm, and the gas inside the balloon reaches a temperature of 40.0°C, calculate the volume of hydrogen gas (in liters) produced. R= 0.08206 l.atm.mol-1.K-1(Hint: Use ideal gas equation to solve this)Show all your steps and formulas used in the calculation.
