Answer: B 150 j

Step-by-step explanation:

I got it right

Answer 2

Step-by-step explanation:

Givens

m = 25 grams

deltaT = 15oC

c = 0.39/(g*oC)

Equation

H = m * c * delta T

Solution

H = 25 * 0.39 * 15

H = 146.25 joules.

I'll let you round to the proper number of sig digs if you are required to.
