What conditions are used in the Haber process to enhance the yield of ammonia? Explain why each condition affects the yield in terms of the Le Chatelier principle
Construct a frost circle for imidazole with one 2p orbital on each atom of the ring, and show relative energy of all pi molecular orbitals. fill in the appropriate number of electrons
STP corresponded to conditions of "standard" temperature (T=0°C) and standard pressure (p= 1 atm). At STP, 1 L of Br2 reacts totally with 3 L of F2 to form 2 L of a product. What is the formula of the product?
Calculate the final temperature when a 29.0 gram sample of ice at 0oC is placed into a styrofoam cup containing 115 grams of water at 75.7 oC. Assume that there is no loss or gain of heat from the surroundings.
the human eye is able to detect as little as 2.35 x 10 ^-18 J of green light of wavelength 510 nm. Calculate the minimum number of photons of green light that can be detected by the human eye.
Calculate P,V and T for initial and final states of each process and produce a plot of the two processes on a P,V diagram. Without resorting to equations, explain why the result for part (b) is greater than or less than the result for part (a).
