Given the reaction at a certain temperature: 2 HI <--> H2 + I2. at equilibrium, the partial pressure of HI is 1.8 x 10^ -3 atm, and the partial pressures for H2 and I2 are 0.10 atm each. Find Kp at that temperature. (show all work)
What other substance(s) found in chocolate bear(s) a strong structural resemblance to caffeine? Draw the structures of these substances and point out the similarities.
Small helium-neon lasers emit 3.60 mJ/s of light at 634 nm. How many photons does such a laser emit in one minute?
Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment.
