A student weighs out 4.16 g of magnesium chloride and adds enough water to make 125.0 mL of solution. The student then weighs out 8.82 g of sodium phosphate and adds enough water to make 250.0 mL of solution. 25.0 mL of the magnesium chloride solution is combined with 25.0 mL of the sodium phosphate solution. a. Write a balanced equation for the reaction that occurs (remember to include phases). b. If a precipitate forms, write the name of the precipitate and calculate the theoretical yield for the precipitate. If no precipitate forms, calculate the limiting reactant. C. If the temperature of the solution decreases, is this reaction exothermic or endothermic?
