For many purposes we can treat ammonia NH3 as an ideal gas at temperatures above its boiling point of −33.°C.Suppose the pressure on a 22.0g sample of ammonia gas at −9.00°C is doubled.

For many purposes we can treat ammonia NH3 as an ideal gas at temperatures above its boiling point of −33.°C.Suppose the pressure on a 52.0g sample of ammonia gas at −15.0°C is tripled.Is it possible to change the temperature of the ammonia at the same time such that the volume of the gas doesn't change? yesnoIf you answered yes, calculate the new temperature of the gas. Round your answer to the nearest °C.

. The thermochemical equation showing the formation of ammonia, NH3 from its elements is:N2 (g) + 3 H2 (g) —> 2 NH3 (g)            ΔH = -92 kJThis equation shows that 92 kJ of heat is ____.*2 pointsabsorbed from the surroundings.released to the surroundings.

When ammonia burns in air, nitrogen dioxide and water are produced according to the reaction below:4 NH3(g) + 7 O2(g) → 4 NO2(g) + 6 H2O(l)At 0 °C and 1 atm pressure, burning 44.8 L of ammonia requires:A.6/7 moles O2.B.8/7 moles O2.C.7/4 moles O2.D.7/2 moles O2.

What is the valency of nitrogen in ammonia (NH3)?
