What is the dew point of a mixture of air and water vapor at 60°C and 1 atm in which the mole fraction of the water is 12%? The total pressure on the mixture is constant.
Compute the pH at the temperature of 25 0C of a solution prepared by mixing 50 mL of 1.60 M sodium hydroxide solution to 0.5 of .0850 M Furoic acid HC 5 H 3 O 3 .
What mass of oxygen (in grams) reacts when 13.2 g of methanol (CH3OH) are combusted in oxygen to produce carbon dioxide and water
A balloon is filled to a volume of 7.00 x 102 mL at a temperature of 20.0 oC. The balloon is then cooled at constant pressure to a temperature of 1.00 x 102 K.
Why E2 is favored over SN2, Sn2 requires a strong nucleophile while E2 requires a strong base. But relatively compared if you have a very strong base the E2 is preferred. Why is it so?
