What is the molar concentration (molarity) of a solution made by dissolving 0.285 moles of CaCl2 (s) in just enough water to form 1.2 liters of solution?

Two alcohols, isopropyl alcohol and propyl alcohol, have the same molecular formula, C3H8O. A solution of the two that is two-thirds by mass isopropyl alcohol has a vapor pressure of 0.110 atm at 313 K.

For a reaction 2A (aq) + BC (aq) = AB (s) + AC (l), the order of reaction with respect to A is 2 and the overall order of reaction is 2, describe methods to increase the rate of the reaction and explain how the methods work?

In this equation: FeBr2+K2CO3=Fe2 (CO3) 2+KBr do I simplify the 2's on iron and the CO3 on the "right side" before continuing or keep them and why?

A volatile liquid is evaporated in a flask in a boiling a water bath ( Temperature = 100°C) with a volume of 297ml. The evaporated gas is condensed in the flask and it is found to have a mass of 0.435g. Atmospheric pressure for that day is 765mmHg.
