A biochemist carefully measures the molarity of salt in  33.mL  of photobacterium cell growth medium to be  54.   mM .   Unfortunately, a careless graduate student forgets to cover the container of growth medium and a substantial amount of the solvent evaporates. The volume of the cell growth medium falls to  9.1mL . Calculate the new molarity of salt in the photobacterium cell growth medium.Round each of your answers to  2  significant digits.

Predict the products (if any) that will be formed by the reaction below. If no reaction occurs, write NR after the reaction arrow. Be sure to include the proper phases for all species within the reaction.   a.) Al(s) + HCl(aq) →  b.) 2 HClO₄(aq) + Co(s) →   c.) Ca(s) + LiCl(aq) →  d.)  FeSO₄(aq) + Zn(s) →

A tank originally contains 500 L of water with a salt concentration of 2 grams per liter. Water with a concentration of 1 gram/liter is then poured into the tank at a rate of 3 L/min and the well stirred mixture is allowed to flow out of the tank at the same rate. a) Find a formula for Q(t), the quantity of salt in the tank after t minutes. b) Find the limiting quantity of salt in the tank as t → co
