Calculate the amount of heat gained by the water in cup 2 after adding the hot object(s) to it.
use the data recorded in parts b and c and the formula q = mcδt. the specific heat capacity of water is 4.186 j/(g °c).
data in part b:
mass of cup 2, empty (g) 3.42
mass of cup 2 with water (g) 82.52
mass of water in cup 2 (g) 79.1
temperature of water in cup 2 (°c) 16.8
data in part c:
temperature of water in cup 1 (°c) 85.0
final temperature of water in cup 2 (°c) 23.2

Iknow #2 is d. i just need to know why

The characteristic of two different types of reactions are shown below. reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of and element. which statement is true about the atoms of the elements that participate in the two reactions? a: their identity changes in both reaction a and b. b: their identity changes in reaction a but not b. c: their identity changes in reaction b but not a. d: their identity remains the same.
