If 0.100 mol of solute is added to 0.500 L of solvent with a density of 0.790 g/mL, the molality of the solution is a. 0.166 m b. 0.253 m c. 1.27x10^-4 m d. none e. 0.200 m : b. This question counts the weight of two questions. The half-life of a reactant in a first-order reaction was measured to be 6.10 hours. If the starting concentration is 1.00 M, what is the remaining concentration after 7.43 hours? The first-order rate equations are ln [A]t = -kt + ln [A]0 and t1/2=0.693/k ...

Vapor Pressure is a form of Dynamic Equilibrium Molecules are constantly moving between phases, but the rate at which the molecules move from the liquid ↔ gas phase is constant Chemical Equilibrium a state in which the rate of a forward reaction and the rate of the reverse reaction are the same as the reaction uses its reactants the forward reaction starts to slow down How is chemical equilibrium reached? reactants and products are still forming when it is reached, just at th...
