Calculate the standard enthalpy change for the combustion of ethene gas (C2H4(g)) to form carbon dioxide gas (CO2(g)) and water vapor (H2O(g)), given the following thermochemical equations: C2H4(g) + 3O2(g) → 2CO2(g) + 2H2O(g) ΔH°=-1411 kJ/mol2H2(g) + O2(g) → 2H2O(g) ΔH°=-484 kJ/mol

Calculate the enthalpy change for the dissolution of 10 grams of sodium hydroxide in excess water, given that the solution formed has a final temperature of 25°C, and the specific heat capacity of the solution is 4.184 J/(g°C). The molar enthalpy of dissolution of NaOH is -44 kJ/mol. Assume that the density of the solution is equal to that of water.
