please help ? part A and B
9. (Basically the same reaction as #8 above, without some of the assumptions) In one experiment, a student placed 50.0mL of 1.00M HCI at 25.5°C in a coffee-cup calorimeter. To this was added 50.0mL of 1.00M NaOH solution also at 25.5°C. The mixture was stirred, and the temperature quickly increased to a maximum of 32.2°C. 2pts a Provide a thermochemical reaction, including AH in kJ. (include sign) b. What is the energy (AH)...

please help me with these three questions! q1. In the coffee cup calorimeter , 0.853 g of MgO were added to 71.4 ml of diluted aqueous hydrochloric acid. If temperature is increased by 5.9 degrees C, wht is q(rxn) in (KJ)? assume that q (cal) is small enough to be negligible. the specific heat capacity of the solution is similar to water (c=4.184), and the density of dilute hydrochloric acid solution is 1.00 g/ml. q2.explain how the signs of q(rxn)...

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction Since the cup itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter and the value determined is called the calorimeter constant Water One way to do this is to use a common metal...
