Why did you use two coffee cups during the experiment instead of just one cup? in case a hole was punctured in the inside cup to add more weight in order to stabilize the calorimeter to hold all of the water in the experiment so that the water temperature would not change at all during the experiment to prevent heat from escaping from the calorimeter

Why did you use two coffee cups during the experiment instead of just one cup?

A-in case a hole was punctured in the inside cup

B-to add more weight in order to stabilize the calorimeter

C-to hold all of the water in the experiment

D-so that the water temperature would not change at all during the experiment

E-to prevent heat from escaping from the calorimeter

the correct answer is E i just got this one right.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

i'm assuming that it's c.) red bank..
