Specific heat to energy temp

Question

A. A sample of gaseous hydrogen is heated with an electrical coil. If 2.58×10³ Joules of energy are added to a 11.8 gram sample initially at 21.0 °C, what is the final temperature of the hydrogen?

Answer:  °C

B. What is the energy change when the temperature of 10.4 grams of solid sulfur is decreased from 35.3 °C to 22.4 °C?

Answer:  Joules

Answer 1

LOL...

HINT:

q = mC∆T

q = 2.58x10³ J

m = 11.8 g

C = look it up

∆T = ? solve for this and add it to 21º
