1) answer: The calcium chloride and phenol red seem to be the most reason behind the chemical reactions.
2) answer: most of the time with the sodium bicarbonate the temperature was lower. But with the calcium chloride the temperature usually got warmer.
3) answer: mostly the color changed to a pink color because if the phenol red. But when the baking soda was added with the phenol red and calcium chloride and baking soda the color changed to pink then yellow then orange.
4) answer: not necessarily. Sometimes the temperature change occurs before the color change. Only by a few seconds, though.
5) answer: all of our experiments were composed with fluid of some sort. Whether it was water or phenol red. It seems to be necessary for the experiment to react correctly.
6) answer: the combination of chemicals that we used in our experiment usually created a new temperature and a new color. Not always a new smell. But throughout the observations I have concluded that a new substance is made through each experiment.
7) answer: maybe mixing the chemical with water would change it a different color.
8) answer: because if there wasn't a retain of any kind then it wouldn't change anything. Temperature is a change. So if it changes temperature then there is a retain going on.
