Question
I need help with question three. I provided the information and also the answer to question 2, which I got 52.824kJ. On question three I just need option: 1,2,&4.
Drink Industry Heats Up the Polar Express As the CEO of a beverage company, you were thrilled to land a big contract with the Polar Express. They need cocoa, and lots of it. However, Aluminum container to make things more magical (and convenient), they want it to come in self-heating cans. The Cappu dente Compartment with CaCl, Chocolate holiday season is only a couple months away, so you need to start product design23875 immediately. You and your board members have gathered to discuss your options. Aluminum foil membrane 3scaute Water Polypropylene can Background: Typically, self-heating cans are designed to combine two or more chemical reactants when the sides of the can are pressed or a button is pushed. This results in an exothermic reaction, which heats the drink without the need for a stove or microwave. You and your board members need to decide which reactants you will be using in your final product. Figure 1: Composite drawing of the self-heating unit provided by students from Universidad Politécnica de Madrid. Option #1: Jasmine did some reading and said that she's seen other companies use the dissolution of calcium chloride in water. CaCl, (s) - Ca²+(aq) + 2 CI-(aq) + 120.0 kJ Option #2: Ramon chimes in and says that he's also seen other companies using the reaction of quicklime (calcium oxide) with water. Ca0(s) + H20(!) → Ca(OH)2(aq) + 63.70 kJ Option #3: Tyler says he came across another option in his research, the dissolution of ammonium nitrate in water. NH, NO, (s) + 25.41 kJ → NH (aq) + NO5 (aq) Option #4: Lucia says that she came across an option to0, although it's normally used for MRES (Meals Ready to Eat, mostly known as military rations), not drinks. Mg (s) + 2 H20(1) → Mg²*(aq) + 2 OH (aq) + H2(g) + 351.0 kJ Your team of scientists knows from all of their beverage experience that the perfect temperature to drink hot cocoa is 77.00 °C. You also know that the drinks will be stored at 15.00 °C on the train. Each can will hold 210.0 ml of cocoa beverage. 2. How much heat will need to be produced to warm a can of cocoa from 15.00 °C to 77.00 °C? Give your answer in kJ. (dcocoa = 1.06 g mL-1; Ccocoa = 3.900 Jg1 °c) 52.824KJ toxs no
