1. The problem statement, all variables and given/known data

This is the final graded assignment before finals, and I want to end on a high note and get all of these right.

"See the Picture Attachment"

2. Relevant equations

Teacher said that $$\sum$$$$\Delta$$Q= 0 ---- so ----
0= Mass(object1)*SpecificHeat(object1)*(Thermal Equilibrium Temp. - Original Heat)
So I used this type of equation for each question.

3. The attempt at a solution

I am going to post my answers and if you don't think they are right say something and then I will explain what I was trying to do, because they are algebra intensive questions.

1. 20 degrees C

2. 39.3 degrees C

3. 84.65 degrees C

4. .0507

5. .0335

6. 45.05 degrees C
