Question 1: We have a calorimetric bomb with a heat capacity of 555 J/K. The bomb contains 1000.0 mL of water. We burn 2.104 g of a solid in the calorimetric bomb. The temperature of the bomb and the water increases by 2.13 oC. The molar mass of this solid is 510.8 g/mol. How much heat would be released (in kJ, and note that we want the amount of heat going out) if we burned 0.136 mol of this solid in the calorimeter bomb? The specific heat of water is 4.184 J/K/g. Assume that the density of water is 1.00 g/mL.

A 70.0-g piece of metal at 80.0 °C is placed in 100 g of water at 22.0 °C contained in a calorimeter like that shown. The metal and water come to the same temperature at 24.6 °C. How much heat did the metal give up to the water? What is the specific heat of the metal?

A material has a specific heat of 0.625 J/g°C.  A 75.6 g sample of this material is heated  and them placed in 35.2 g of water at 21.4 °C.  The temperature of the water rises to 32.7 °C.  What was the initial temperature of the material?

(please type answer no write by hand)

Mixing 50 ml of HCI ( 2.0 M) with 50 ml of NaOH ( 2.0 M ) raises the temperature of the calorimeter from 23.0 C to 31.0 C. What is the heat of reaction per mol of HCI ? 40.3 KJ/mol 32.2 KJ/mol O 38.4 KJ/mol 33.5 KJ/mol

A chemist burned a sample of coal in a bomb calorimeter. Her results are below. Calorimeter's Heat Capacity 7.264 kJ/°C Mass of Coal Initial Temperature Final Temperature 0.100 g 22.07°C 25.37°C The sample of coal that the chemist placed in the bomb was dry but when she finished the test there was a small amount of water in the bomb. Where did this water come from and how does it affect her result? The water came from the water surrounding the bomb so her measured heat of combustion is for a closed system. The water was a product of combustion so her measured heat of combustion is for an open system. The water came from the water surrounding the bomb so her measured heat of combustion is for an open system. The water was a product of combustion so her measured heat of combustion is for a closed system.

A nickel at 30 °C is dropped into a glass of 15.0 g soda at 3.0 °C, if the heat capacity of the nickel is 4.40 J/°C, the heat capacity for the glass is 11.1 J/°C, and the soda has the same specific heat capacity as water (4.184 J/g°C), what is the final temperature of the mixture?

Can you explain where did I go wrong, I keep getting the same answer.
