Chemistry in bag.

in the experiment with sodium bicarbonate, water, and fenol red it got really cold at first and released some gas. it smells really bad. the color turned pink.

in the experiment with water, calcium chloride, and fenol red it got really hot and it smells like alcohol. the color turned pink.

in the experiment with water, calcium chloride, fenol red, and sodium bicarbonate it stayed at a neutral temparture, and had a smell similar to rubing alcohol. and the color turned orange and yellow.

1. the temparture change was contributed by the sodium bicarbonate and calcium chloride.
2. yes it got cold when it was just sodium bicarbonate, water, and fenol red. and it got hot when it was just calcuim chloride, water, and fenol red.
3. yes when all the chemicals mix together they turn orange but when its just one or the other it turns pink.
4. yes.
5. no.
6. the fenol red and water.
7. no.
