Question

A bag of potato chips contains 585 mL of air at 0.998 atm and 28°C. Assuming the bag does not break, what will be its volume at the top of a mountain where the pressure has dropped to 445 mmHg and 5.4°C? Nitrogen reacts with powdered aluminum according to the following chemical equation: 2 Al(s) + N2 (g) 2 AIN (S) How many liters of nitrogen gas are required to react with 22.3 g of powdered aluminum if the reaction occurs at 825 torr and 89°C?
