In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. A student heats 63.65 grams of zinc to 98.92 °C and then drops it into a cup containing 76.71 grams of water at 22.10 °C. She measures the final temperature to be 27.79 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.79 J/°C. Assuming that no heat is lost to the surroundings calculate the specific heat of zinc. Specific Heat (Zn) = J/g°C.

You want to determine the heat capacity of an unknown metal sample in order to help identify it. To do this, you decide to perform a coffee cup calorimetry experiment. The steps you performed were as follows: 1. Placed a 31.18 g piece of the metal in a boiling water bath at 98.1 °C 2. After the metal has had enough time to heat up, the hot metal is transferred to a coffee cup calorimeter containing 55.22 g of water. 3. The initial temperature of the coffee cup water was 23.06 °C and the final temp 33.66 °C.
10 A student heats 84.17 mL of water to 95.27°C using a hot plate. The heated water is added to a calorimeter containing 73.92 mL of cold water. The water temperature in the calorimeter rises from 2.15°C to 37.48°C. The specific heat capacity of water is 4.184 J and the density of water is g. °C 1.00 mL Assuming that heat was transferred from the hot water to the cold water and the calorimeter, determine the heat capacity of the calorimeter. J Heat capacity of calorimeter = °C
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)
They are all one question. In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction.A student heats 60.42 grams of chromium to 98.12 °C and then drops it into a cup containing 82.86 grams of water at 23.37 °C. She measures the final temperature to be 28.57 °C.The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.80 J/°C.Assuming that no heat is lost to the surroundings calculate the specific heat of chromium.Specific Heat (Cr) = ______J/g°C. In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction.Since the cup itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is…
When 14.2 g KBr is dissolved in 100.0 g of water in a coffee-cup calorimeter, the temperature drops from 28.88 °C to 23.38 °C. What is the enthalpy change per gram of KBr dissolved in the water? Assume that the solution has a specific heat capacity of 4.18 J/g·K.
When a reaction that was known to release 17.55 kJ of heat took place in a calorimeter and containing 100 mL of water, the temperature rose by 3.65°C. When 50 mL of HCl was mixed with 50 mL of aqueous NaOH solution in the same container, the temperature rose by 1.15°C. How much heat was released by the neutralization reaction?
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.
