At 1000K, the equilibrium constant Kc for the reaction is 3.80x10-5. Suppose you start with 0.0356 of I2 in a 2.30 L flasg at 1000K. What is the concentration of the atomic gas at equilibrium?
Suppose Joule encountered the waterfall at Niagara Falls. Calculate the height if the temperature difference between the top and bottom of the waterfall is 0.20° F.
A gaseous fuel mixture stored at 752 mmHg and 298 K contains only methane and propane . When 11.6L of this fuel mixture is burned, it produces 767kJ of heat.
want to synthesize 3-methyl-2-pentene from 2-chloro-3-methylpentane. Which reagent would you use
A solution of 0.1% sodium dodycl sulfate (SDS) binds so strongly to polypetide chains that one detergent molecule is sufficient to saturate two amino acid residues.
