18) Nitrous oxide may be formed according to the below equation: NH4NO3(s) →N20(g) + 2H2O(g) What mass of NH4NO3(s) is required to produce 145L of N20(g) at 42.0C and 3.75atm?

Gaseous iodine pentafluoride, IF₅, can be prepared by the reaction of solid iodine and gaseous fluorine: I₂(s) + 5F₂(g) → 2IF₅(g) A 10.00 L flask is charged with 15.0 grams of I₂ and 2.00 atm of F₂ at 25°C. The flask is heated to 100°C until one of the reagents is completely consumed. What will be the percentage of IF₅ (by mole) in the final product mixture? (Assume ideal gas behavior).

The combustion of octane, C8H18, proceeds according to the reaction shown.   2C8H18(l)+25O2(g)⟶16CO2(g)+18H2O(l) If 611 mol of octane combusts, what volume of carbon dioxide is produced at 35.0 ∘C and 0.995 atm?

Wetlands can play a significant role in removing fertilizer residues from rain runoff and groundwater; one way they do this is through denitrification, which converts nitrate ions to nitrogen gas:   1)Suppose 295 g of NO3- flows into a swamp each day. What volume of N2 would be produced each day at 17.0°C and 1.00 atm if the denitrification process were complete? 2)Suppose 295 g of NO3- flows into a swamp each day. What volume of CO2 would be produced each day at 17.0°C and 1.00 atm?    3)Suppose the gas mixture produced by the decomposition reaction is trapped in a container at 17.0°C; what is the density of the mixture assuming Ptotal = 1.00 atm?
