How many moles of NH3 from when 32.4 L of H2 gas completely reacts at STP according to the following reaction? Remember 1 mol of an ideal gas has a volume of 22.4 L at STP
N₂(g)+3H₂(g)→2NH₃(g)

ps: We have to not only give the answer which is 1.45 mol NH3 but we have to show the equation of how we got to it.

Which of the following is true about the speed of light? it depends on the wavelength.

The molar mass of cu is 63.55 g/mol. the number of grams of cu produced in this reaction is

Using this reversible reaction, answer the questions below: n2o4 2no2 (colorless) (reddish-brown) -as the temperature increased, what happened to the n2o4 concentration? -was the formation of reactants or products favored by the addition of heat? -which reaction is exothermic? right to left or left to right? -if the change of enthalpy of this reaction when proceeding left to right is 14 kcal, which chemical equation is correct? n2o4 2no2 + 14 kcal n2o4 2no2, hr = +14 kcal n2o4 + 14 kcal 2no2 n2o4 2no2, hr = -14 kcal
