3 Question (1 point) A 296.0 g piece of granite, heated to 551.0°C in a campfire, is dropped into 1.20 L water (d - 1.00 g/ml) at 25.0°C. The molar heat capacity of water is Gpwater = 75.3J/(mol-C), and the specific heat of granite is granite = 0.790 J/g °C). 4th attempt hi See Peri Calculate the final temperature of the granite.
4. Heat transfer: q = mass x Cs x ΔT and –qreaction = +qsolution a. A piece of metal with a mass of 8.6 g was heated to 100.0°C and dropped into a coffee cup calorimeter containing 402.4 g of water at 25.0°C. If the temperature of the water and the metal at thermal equilibrium is 26.4°C, what is the specific heat of this metal in J/g°C? b. How much heat energy must be added in order to boil a...
A 92.5 g piece of aluminum (which has a molar heat capacity of 24.03]/°C-mol) is heated to 624°C and dropped into a calorimeter containing water (specific heat capacity of water is 4.18 J/g°C) initially at 19.2°C. The final temperature of the water is 135.2°C. Ignoring significant figures, calculate the mass of water in the calorimeter.

Question 2 1 pts Suppose you are investigating the reaction: M(s) + 2 HCl(aq) → MCl2(aq) + H2(g). You weigh out a 0.202 gram piece of metal and combine it with 62.2 mL of 1.00 M HCl in a coffee-cup calorimeter. If the molar mass of the metal is 48.51 g/mol, and you measure that the reaction absorbed 111 J of heat, what is the enthalpy of this reaction in kJ per mole of limiting reactant? Enter your answer...
a) Find U for the change in state of 1.0 mol H2O (l) at 83 C to H2O (g) at 114 C. The molar heat capacity of H2O (l) = 75.3 J mol-1K-1, molar heat capacity of H2O (g) = 25.0 J mol-1K-1, and the heat of vaporization of H2O is 40.7 x 103 J mol-1K-1 at 100 C. b) Find ΔH for the change in state of 1.0 mol H2O(l) at 83 ∘C to H2O(g) at 114 ∘C. c)...
