What volume of a 0.125 M NiCl2 solution contains 3.25 g of NiCl2?

If a reaction has g of -136kj at 110°c, will it be spontaneous at this temperature (110°c)? yes or no

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Sodium sulfate dissolves as follows: na2so4(s) → 2na+(aq) + so42- (aq). how many moles of na2so4 are required to make 1.0 l of solution in which the na concentration is 0.10 m?
