The Reaction of Sodium and Chloride media type="custom" key="11349166" width="120" height="120" There was a temperature change because it was exothermic; it gave off heat. Also, precipitation was forming because the steam was given off of the heat. They put a rock of sodium under the straw-like tube and trickled down chloride. That was how the chemical reaction was formed.

Bromine and Alcohol media type="custom" key="11349306" width="120" height="120" For this lab, the indentifiers were color change and precipitation. First, the liquid was a yellow-like substance. Then, it changed into a dark orange-red color when the chemical reaction was formed. Also, gsas was given off because it started to bubble and steam. Those were the identifiers, and the description is that it was really cool to see such an inmmense change just from two combinations to make/create a chemical reaction. Potassium and Water media type="custom" key="11349360" width="119" height="119"

In this lab, the heat and fire caused the water to look like it had a color change, which it did. The fire was giving off an exothermic heat; it gave off heat. The fire was circling around the water and because of the chemical reaction. It was cool to see because it looked like fire was floating on water; which was the chemical reaction between potassium and water.
