Consider the chemical equation:
CuSO4 x 4NH3 (s) <-------> CuSO4 x 2NH3 (s) + 2NH3 (g) the arrow is an equilibrium arrow. it goes both ways
At 20 degrees Celcius the equilibrium pressure of NH3 (g) is 62 Torr. Calculate the value of Kp for this equation and include the corresponding units.
using a gas sample of 757 ml is compressed at stp to a volume of 118 ml and the temperature raised to 39 degrees c.
Assuming that radiation with ?=15.0 cm is used, that all the energy is converted to heat, and that 4.184 J is needed to raise the temperature of 1.00 g of water by 1.00 ^0C , how many photons are necessary to raise the temperature of a 350 mL cup ..
What is the formula of a compound that crystallizes with copper ions occupying one-half of the tetrahedral holes in a FCC array of fluoride ions
A solution is prepared by dissolving 159 g of sucrose (C12H22O11) in 624 g of water. What is the vapor pressure of this solution at 30°C? (The vapor pressure of water is 31.8 mmHg at 30°C.)
For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species. For the reaction C2H6 (g)+ H2 (g) -> 2CH4
A flask contains 0.180 mol of liquid bromine, Br_2. Determine the number of bromine molecules present in the flask.
some species of bacteria can oxidize nitrite to nitrate using the energy released by the transfer of electrons to oxygen to drive ATP synthesis. Given the E values below, calculate the max yield of ATP per mole of nitrite oxidized.
NH3 and NH4+ are used to create a buffer solution. When a base is introduced into this buffer, which of NH3 and NH4+ reacts with the base to maintain the pH of the solution
