A 100g mass of tungsten at 100 degrees C is placed in 200 mL of water at 20 degrees C
a cup contains 100g of water at 10°c. if 100 g of 50 degrees celsius water is added, what will the temperature of the mixture be?
A 200 g ice cube at -20 degrees Celsius is placed in 1.00 kg of water at 25 degrees Celsius in a 50 g aluminum calorimeter also at 25 degrees Celsius. A. How much heat does the ice cube absorb as it reaches its melting point? B. How much heat does the ice cube absorb as it melts? C. What is the final tempreature pf the mixture? D. How much heat does the water in the calorimeter lose as it...
An aluminum cup of unknown mass contains 200 g of water and a 100 g copper stirrer, all at 20 degrees Celsius. A 600 g sample of silver at an initial tempreature of 100 degrees Celsius is placed in the water. The stirrer is used to mix the water until the mixture reaches thermal equilibrium at 30 degrees Celsius. A. How much heat does the water absorb? B. How much heat does the copper stirrer absorb? C. How much heat...
I am currently working 6.45. I had the equation set up
corrctly until i got to the circled portion of the second picture.
I dont understand why they multiplied the (10J/C) by (Tfinal -
22.8C) when i already had (Tfinal -22.8C) in the equation right
before that.
I hope that makes sense. Thank you!

Calculate the amount of heat energy, q, produced in each
reaction. Use 1.03 g/mL for thedensity of all solutions. Use the
specific heat of water, 4.18 J/(g•°C), for all solutions.
The temperature change in part 3 was 15.5 degrees celsius.
Temperature change in part 4 was -1.2 degrees celsius.
Then determine the enthalpy change for each reaction in terms of
kJ/mol of each reactant.
The molarity of NaOH is 2.0 M.
Part III Conduct the Reaction Between Solutions of NaOH...
