In a simple calorimeter, a piece of metal weighing 48.67 g was heated to 120.0 °C and then put it into 100.0 mL of water (initially at 23.7 °C). The metal and water were allowed to come to an equilibrium temperature, determined to be 27.8 °C. Assuming no heat lost to the environment, calculate the specific heat of the metal. Is this process endothermic or exothermic? Explain. Show Your Work
Calculate the energy content (in calories) of a 1.00 g of product that is placed inside a calorimeter having a heat capacity of 950 J/K. Data from the calorimeter indicated that the 3.0 L surrounding water had initial and final temperatures of 18.0 °C and 47.5 °C, respectively. Specific heat capacity of water: 4.18 J/g-K * O 2.6x10^4 cal O 9.5x10^4 cal O 8.8x10^4 cal 7.3x10^4 cal
Question 5 of 26 Fill in the blanks: A substance having a mass 1.5 g is burned in a bomb calorimeter. The temperature started at 20.2 °C and leveled off at 23.5 °C. The manufacturer of the bomb calorimeter determined the heat capacity of the calorimeter to be 15.3 kJ/°C. Calculate the heat of combustion per gram of the given substance. Type your answer in whole number. kJ/g Answer:
A 5.71 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72 °C. After the salt has completely dissolved, the temperature of the solution is 28.54 °C. What quantity in moles of the unknown salt were used in the reaction?
6. Determine the mass of a sample of water in a coffee cup calorimeter if the final temperature is 65.7 °C, the initial temperature is 22.3 °C, and 27.6 kJ of heat is added to the water (specific heat of water is 4.184 J/g•K).

You have 8.99 g sample of an unknown salt (MM = 116.82 g/mol). It is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72°C. After the salt has completely dissolved, the temperature of the solution is 28.54°C. What is the Mass inside calorimeter (g)? Change in Temp inside calorimeter (C)? How much Heat gained (J)? Total Heat? How many mols of the unknown salt? What is the change in empalthy?
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
The answer is 44.8 kJ/mol. Show the solution how to get 44.8 kJ/mol.
In order to break water into hydrogen and oxygen, water is heated to more than 500°C. Which kind of reaction is this and why? It is exothermic because heat needs to be released by the reactants to form the products. It is endothermic because heat needs to be released by the reactants to form the products It is exothermic because heat needs to be absorbed by the reactants to form the products. It is endothermic because heat needs to be absorbed by the reactants to form the products.
A 7.37 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter.
