A) When 1.911 grams of sucrose (Molar mass 342.3 g/mol) is burned in a bomb calorimeter, the temperature of the calorimeter increases from 22.410 °C to 26.630 °C. If the heat capacity of the calorimeter is 4.900 kJ/ °C, what is the heat of combustion of sucrose, in kJ/mol? And B) A 90.0 g piece of metal, initially at 98.60 °C, is placed into 120.0 g of water initially at 24.30 °C. If the final temperature of the water is 34.00 °C, what is the specific heat of the metal? (The specific heat of water is 4.184 J/g･ °C).

150.0 mL of dilute hydrochloric acid is placed in a coffee cup calorimeter. The initial temperature of the solution is recorded to be 14.5°C. A piece of magnesium ribbon of mass 0.575 g is placed in the solution and allowed to react. If the molar enthalpy change for this reaction is -584 kJ/mol, what final temperature would you predict?

A 1.200 g sample of ZnCO3 (s) dissolved in 40.0 mL of a dilute HCl solution (density = 1.10 g/mL) in a coffee cup calorimeter, producing CO2 (g), liquid water and ZnCl2 (aq).  The temperature of the solution changes from 24.32 oC to 25.49 oC.  The resulting solution has a specific heat of 4.18 J/goC. What would be a balanced equation for this reaction.

A certain chemical reaction releases 269. kJ of heat energy per mole of reactant consumed. Suppose some moles of the reactant are put into a calorimeter (a device for measuring heat flow). It takes 3.21 J of heat energy to raise the temperature of this calorimeter by 1 °C. Now the reaction is run until all the reactant is gone, and the temperature of the calorimeter is found to rise by 5.0 °C. How would you calculate the number of moles of reactant that were consumed? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols. moles consumed = x10 010 X Ś
