Given the balanced equation below for the highly exothermic reaction of aluminum with oxygen to form aluminum oxide: What is the value of ΔH when 1.00 mol of aluminum reacts? What is the value of ΔH when 5.23 g of aluminum reacts? What is the value of ΔH when 6.17 L of oxygen gas at STP reacts with excess aluminum? A certain reaction releases 6881 kJ of heat. What mass of aluminum oxide was produced in the reaction?

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
