__Experimental Design__~
Question: What are some signs that a chemical reaction is taking place? Hypothesis: Change in color, change in odor, and a precipitate. Independent Variable: Combination of chemicals in the test tube. Dependent Variable: Signs of a chemical reaction. Constants: Amount of each mixture (solid- .5 grams and liquid- 15 mg)

__Background__~
Calcium Chloride: Medicine, injection, salt substitute, burns skin if skin is moist. Sodium Bicarbonate: Medicine (helps heart burn), baking soda. Bromothymol Blue: Dye content, ACS reagent. Water: H20, drink.

__Summary:__
We took 7 combinations of chemical and experimented with them to find out how they would react. We took Calcium Chloride, Bromothymol Blue, Sodium Bicarbonate, and water, and made combinations with them. We would measure the temperature of just one chemical, then the other, and then combine them. Most of them changed temperature. Finally, we combined 3 chemicals once, which made the most notable reaction. Most of the chemicals dissolved in water, or stayed completely separate. Calcium chloride and sodium bicarbonate can combine and create an acid, a gas, and a. This can happen because molecules can In conclusion, only one combination of 3 chemicals really made a big reaction, most of them only bubbled or did nothing.

__Conclusion__~
We tested a total of 8 combinations of calcium chloride, sodium bicarbonate, bromothymol blue, and water. Some of the chemicals stayed separate, slowly dissolved, and only some actually changed colors. For example, bromothymol blue and calcium chloride stayed separate, slowly dissolved, and barely changed color. However, sodium bicarbonate and water mixed with calcium chloride and water began to fizz, bubble, and turned white. We came to the conclusion that if the substance dissolved and didn't really do anything, then a chemical reaction had not occurred. But, if a change in color, odor, temperature, or bubbling occurred, then a reaction is taking place.
