Assume you use calorimetry to calculate the specific heat capacity of a 125.24 g piece of unknown metal. You intially heat the metal to 100.0 °C in boiling water. You then drop the chunk of metal into a calorimeter containing 47.22 g of water at 19.7 °C. After closing and stiring the calorimeter thoroughly, the metal and water both come to equilibrium at a temperature of 27.6 °C.
Part A
What is the temperature change of the water?
100.0 °C
19.7 °C
7.9 °C

Part B
What is the temperature change of the metal?
-72.4 °C
125.2 °C
-27.6 °C

Part C
How much heat was gained by the water? (calculate the qwater)
33.1 J
1561 J
418.4 J

Part D
Knowing the above, what must qmetal?
-33.1 J
-1561 J
-125240 J

Part E
Then what must the the Specific Heat of the metal be?
0.4184 J/g°C
25.00 J/g°C
0.1721 J/g°C

In this virtual lab, you will use coffee cup calorimetry to determine the specific heat, c, of a metal.
Imagine that, in lab, you record the mass of a piece of metal, m_metal, as
m_metal = 45.00 g
In the next step of the lab (as shown in the animation in the attached document) you heat uo the piece of metal.

The following acid-base reaction is performed in a coffee cup calorimeter:
H+(aq) + OH-(aq) --> H2O(l)
The temperature of 110 g of water rises from 25.0°C to 26.2°C when 0.10 mol of H+ is reacted with 0.10 mol of OH-.
Calculate qwater,
Calculate ΔH for the reaction,
Calculate ΔH if 1.00 mol OH- reacts

Calculate the final pH of 25 mL of buffer 0.1M Tris.HCl/Tris buffer, pH=6.60 after the addition of 1.00mL of 0.1M NaOH. pKa is 8.08.
use the 0.10M Tris.HCl and 0.10M Tris to prepare 100mL, pH=6.6 solution. it calculated by pre-lab, it need 96.8 mL 0.10M Tris.HCl and 3.2mL Tris. and take 25mL pH=6.6 solution, then add 1mL of 0

Procedure:
1. Take a calorimeter from the glassware shelf and place it on the workbench.
2. Take a balance from the tools shelf and drop it on the calorimeter. Record the mass of the empty calorimeter.
3. Take a thermometer from the tools shelf and drop it onto the calorimeter. Record the temperature of the calorimete

When steam condenses to liquid water, 2.26 kj of heat is released per gram. The heat from 168g of steam is used to heat a room containing 6.44 x 10 to the 4th grams of air (20ft x 12 ft x 8 ft). The specific heat of air at normal pressure is 1.015 j/(g.C). What is the change in air temperature, assuming the heat from the stea

A lab experiment dealing with the properties of a coffee cup calorimeter was completed. One of the procedures involved measuring the temperature of 50mL water placed in a calorimeter for 3 minutes, and then adding NaOH(s) pellets and measuring the temperature for 4 more minutes. I have several temperature measurements, but I am

The time per week a student uses a lab computer is normally distributed, with a mean of 6.2 hours and a standard deviation of 0.9 hours. A student is randomly selected. Find the probability that the student uses a lab computer between 5.7 and 6.5 hours per week and the probability that the student uses a lab computer more than 5
