Ammonia NH3 (g) forms according to the recation 1/2 N2 (g) + (3/2) H2(g) = NH3 (g). some N2(g) and H2(g) are placed in a constant volume reaction chamber with partial pressure of 1atm and 3atm respectively at 298.15K. a. determine the partial pressures of each gases at equilibrium. b.determine the equilibrium constant at 350.15 K
At a certain temperature, the equilibrium constant, Kc, for this reaction is 53.3. H2(g)+I2(g) 2HI(g) Kc=53.3 At this temperature, 0.800 mol of H2 and 0.800 mol of I2 were placed in a 1.00-L container to react. What concentration of HI is present..
A buffer is composed of 0.400 mol H2PO4^- and 0.400 mol HPO4^2- diluted with water to a volume of 1.00 L. The pH of the buffer is 7.210. How many moles of HCl must be added to decrease the pH to 6.210?
A solution is prepared by dissolving 20.0 g of K2HPO4 and 25.0 g of KH2PO4 in enough water to produce 1.0 L of solution. What is the pH of this buffer
with a solution in them connected by a liquid salt bridge junction filled with KNO3. In one solution you have a graphite electrode that is connected with a wire to a copper electrode in the second soution. The soution in contact with the graphite ..

Sodium bicarbonate is often used as an antacid to neutralize excess hydrochloric acid in an upset stomach. What mass of hydrochloric acid (in grams) can be neutralized by 2.3g of sodium bicarbonate?
A graduated cylinder contains 155 g of water. A 11.0 g piece of iron (density = 7.86 g/cm^3) and a 16.0 g piece of lead are added. What is the new water level in the cylinder?
the reaction mechanisms could be coupled, how many moles of ATP will be needed to drive
How many moles of HCl are present in 35.5 mL of a 0.200 M solution? 2. A 50.0 mL sample of a 6.0 M solution of HCl is diluted to 200. mL. What is the new concentration
A student mixes 5.0 mL 2.00 x 10-3 M Fe(NO3)3 with 4.0 mL 2.00 x l0-3 M KSCN, and 1.0mL deionized water. She finds that in the equilibrium mixture the concentration of FeSCN2+ is 1.2 x l0-4 M.
How would the ground-state energy levels of X and H compare and would the energy of an electron in the n = 2 level of H be higher or lower than that of an electron in the n = 2 level of X? Explain your answer.
The carboxylate groups in sugammadex play an important binding role in locking rocuronium into the central cavity of the cyclodextrin, but they also have an important role in allowing the drug access to the cavity.
