a Sample of MgCl2 is known to be contaminated with NaCL. A 3.47 portion of the sample is dissolved in water and treated with an excess AgNO3 solution. THe precipitate is filtered off, dried and weighed. The dried precipitate weighs 10.3g. Calculate the amunt of MgCl2 in the original sample (in weight percent).
CaCO3 (100.1 g/mol) has a solubility of 0.018 g/100 mL in water at 35?C. What is the value of Ksp at this temperature?
that the reaction was endothermic. If the enthalpy of reaction is negative, then we say that energy was released or that the reaction was exothermic. Most chemical reactions are exothermic.
