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).

In a popular television series, the two characters use thermite to assist with breaking into a chemical storage facility because the reaction between aluminum and iron(III) oxide produces a tremendous amount of heat. If they began with 10.0 g of Al, how many kJ of heat would be released? 29. 2 Al(s) + Fe,O3(s) → Al,O;(s) + 2 Fe(s) AH = -852 kJ 158 kJ A) B) 236 kJ 472 kJ D) None of the above

When 6.54 grams of Zn is placed in 500.0 mL of 1.00 M CuSO4(aq) in a coffee cup calorimeter, it reacts completely to displace copper. The temperature of the solution rises from 20.0˚C to 30.4˚C. Assume the coffee cup itself gains no heat and that the solution has the same density (1.00 g/mL) and specific heat (4.184 J/g˚C) as pure water. (a) How much heat does the solution gain during this reaction? (in J)

In a coffee-cup calorimeter, 59.0 mL of 0.100 M AgNO3 and 59.0 mL of 0.100 M HCI are mixed to yield the following reaction. Ag (aq) + Cl(aq) → AgCl(s) The two solutions were initially at 19.10°C, and the final temperature is 19.90°C. Calculate the heat that accompanies this reaction in kJ/mol of AgCl formed. Assume that the combined solution has a mass of 118.0 g and has a specific heat capacity of 4.18 1/°C 9- 407 kJ/mol

At constant volume, the heat of combustion of a particular compound is −3733.0 kJ/mol.−3733.0 kJ/mol. When 1.361 g1.361 g of this compound (molar mass=185.51 g/mol)(molar mass=185.51 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter, including its contents, rose by 8.567 ∘C.8.567 ∘C. What is the heat capacity (calorimeter constant) of the calorimeter?

The combustion of propane, C3H5, is found to have a heat of combustion of -332 0 kJ/mol of propane burned. How many grams of propane would have to be burned in order to heat 225.0 g of water for Instant coffee from 15.00 °C to 90.00°C?

In the following reaction, how many grams of CH3OH are required to produce 1.578 x 10° kJ of heat? 2 CH3OH (1) +3 O2 (g) → 2 CO2 (g) + 4 H2O(g) AH = -1280. kJ/mol Please do not include units in your answer.

When a 6.50 g sample of solid sodium hydroxide dissolves in 100.0 g of water in a coffee-cup calorimeter, the temperature of the water rises from 21.6 to 37.8oC. Was the chemical reaction (dissolving the solid) endothermic or exothermic? How do you know? Write a balanced chemical equation for this process. Determine how many joules of heat (q) were involved in changing the temperature of the water. If the heat that changed the temperature of the water was a result of the chemical reaction, determine the ΔH of the chemical reaction in kJ/mol of sodium hydroxide.

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. 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?
