Liquid ammonia ionizes to a slight extent. 2NH3(l) > NH4^(+) + NH2^(-). At -50 degrees Celsius, its ion product is K(NH3) = [NH4^(+)][NH2^(-)] = 10^(-30). How many moles of amide ions, NH2^(-), are present per mm^3 of pure liquid ammonia?
What is its solubility under atmospheric conditions? (The partial pressure of CO2 in air is 0.00055 atm.) Assume that CO2 obeys Henry's law.
Draw a diagram showing the hydrogen bonding of an ammonia molecule with two other ammonia molecules. (Draw complete Lewis structures.
Calculate Pt, in atm, for three different gases at partial pressure of 144cm, 800mm, and 1.3m of Hg.
Aspirin that has been stored for a long time may give a vinegar odor and give a purple color with FeCl3, what reaction would cause this to happen
For each reaction, identify the substance being oxidized and the substance being reduced. Express answers as chemical formulas for oxidized and reduced answers. 1. 2Sr(s)+O2(g)----->2SrO(s) 2. Ca(s)+Cl2(g)---->CaCl2(s) 3. Ni^2+(aq)+Mg^2+(aq)+Ni(s)
how many moles of nitrogen are in 5.3 L container at 1.25 atm and a temp of 85 degrees C.
Why does aluminum hydroxide readily dissolve in concentrated NaOH but not in concentrated NH3. Please give a thorough explanation, not just a short answer.
A 3.18 L sample of hydrogen chloride (HCl) gas at 1.64 atm and 31 degrees C is completely disolved in 710 mL of water to form hydrochloric acid solution. Calculate the molarity of the solution. Assume no change in volume
What is the pH of the solution obtained when 135 mL of 0.618 M NaOH is diluted to 16.0 L with water?
Determine which of the following reactions are oxidation-reduction reactions and which are not. what type of reaction do you have if it is not an oxidation-reduction reaction?
undergo an isothermal compression until the pressure of the system is four times the original pressure. The process may occur in two ways:
Beaker contains aq soln of 6.94*10^-3M NiCl_2. beaker contains aq soln of 2.06*10^-5M Na_2CO_3. the two solns are mixed together (no volume change) if NiCO_3 has a Ksp of 1.42*10^-7 what do you expect to see?
