1) Let us begin with this open-ended question.
Suppose that at equilibrium for the reaction shown below there is a much greater amount of ammonia than hydrogen gas.
2 NH3 (g) 3 H2 (g) + N2 (g)
Explain what might cause the equilibrium to be more heavily weighted towards the reactants.
B: A 75.0 mL colume of 0.200 M NH3 (Kb=1.8x10^-5) is titrated with 0.500 M HNO3. Calculate the pH after the addition of 27.0mL of HNO3.
Ammonia, NH3, reacts with the hypochlorite ion, OCl-, to produce hydrazine, N2H4. How many moles of hydrazine are produced from 5.85 mol of ammonia if the reaction has a 78.2%
Calculate the mass in a sample of gold (Au) that absorbs 225 J to change its temperature from 15.0oC to 47.0oC.
Your bedroom is 18 ft long and 15 ft wide, and the distance from floor to ceiling is 8 ft 6 in. You need to know the volume of the room in metric units for some scientific calculations. What is the room's volume in cubic meters
The bp of the solution was 104.3C when 40 g was dissolved in 150mL of water. I lose points if I am more than 5% off. Any ideas what the actual substance might have been? Keep in mind this is a college gen chem lab.
The inclined plane is supported by a horizontal table. Both the cube and the inclined plane can move without friction along the surfaces that support them (the inclined plane and the table, respectively). What is the normal force on the inclined p..
A large flask with a volume of 936mL is evacuated and found to have a mass of 134.66 g. it is then filled to a pressure of 0.967atm at 31 C with a gas of unknown molar mass and then reweighed to give a new mass of 135.91 g. what is the molar mass ..
