Calculate the number of moles of sodium hydroxide that will completely react with the amount of olive oil and Crisco shortening that you are using (15g olive oil and 34g Crisco). Assume that the chemical formula for olive oil is C55H102O6 and that the average molar mass of Crisco shortening is 870g.
Consider: 2 B5H9 (g) + 12 O2 (g) ? 5 B2O3 (g) + 9 H2O (g) ?H?reaction= - 8687 kJ. What is the enthalpy change when 0.2500 moles of B5H9 are combusted
