A balanced, generic thermochemical equation is shown below.  A, B, and C are substances involved in the reaction.  The energy written in the equation is a value of ΔH.  Show all work.  2A +3B+42kJ ---> 1C c) If 50.0 g of A is reacted in the presence of excess B, how much heat is transferred by the reaction? Take the molar mass of A to be 78.70 g/mol. d) Suppose the heat from part (c) is transferred directly to/from 100.0 grams of water held in a separate container. Cs (water) = 4.184 J/(g∙°C).          i) Draw a schematic diagram of the experiment. I am looking for the direction of heat flow between the two entities in your "universe."           ii) Calculate the ΔT of the water. Make sure to include the sign of ΔT.  If you were not able to solve part (c), assume that qrxn = −25 kJ.          iii) Briefly explain (in about 1 sentence) why your result from part d(ii) makes physical sense.
