I just need the answers to B and D. Thanks!

Chm 130L Quiz Week 6: Specific Heat Name Date Score--/ 10 This is a Take-Home Quiz that is due at the beginning of the next class 1) A 32.595 g sample of an unknown metal was heated to 98.5+C in a hot water bath metal was then placed in a calorimeter containing 65.0 mL of water (d g/mL) at a temperature of 28.4*C The final temperature of the water and metal samplo was recorded 8 ensity 1.00 as 30.2\'C. Answer the folowing questions (2 pts each) given the folowing: dT TFrw. Tina Specific Heat (s) : heat-, a- (mass)MAT) mAT a) Determine the temperature change for the water contained in the calorimeter. (2 pts) b) Calculate the heat (q) absorbed by the water in the calormeter (pravide answer with 3 significant figures). NOTE Specific Heat of water is 4.184 Jg C (3 pts) c) Determine the temperature change for the unknown metal sample. (2 pts) d) Calculate the specific heat of the unknown metal sample. Assume the heat given away by the metal equals the heat absorbed by the water in the calorimeter (ie., qreta) (provide answer with 3 significant figures) (3 pts)

Solution

A.

Temperature change of water in colorimeter = 30.2 - 26.4 = 3.8 degree C

B.

Heat absorbed by water = 65.0 * 4.184 * 3.8 = 1033.4 J

C.

Temperature change of metal = 30.2 - 98.5 = 63.3 degree C

D.

1033.4 = 32.595 * specific heat * 63.3

Specific heat of metal = 0.499 J / g-mol
