We mixed 4 chemicals, recorded their reaction, then depicted which chemical mixtures contributed what reactions.



Chemicals
Calcium Chloride- white, ballish clumps, no smell
Phenol Red- Red liquid no smell (will stain skin and clothing)
Sodium Bicarbonate- white, powdery, no smell (baking soda)
Water- clear liquid, no smell

We used one spoon of Calcium Chloride, one spoon of Sodium Bicarbonate, one pipet of Phenol Red, one pipet of water, per test.





all four chemicals mixed reactions- heat in the begining, expanding, bubling liquid, color change,cold at the end, thick liquid at the end (dried to the sides of the bag), simlar smell to paint.





Water and Sodium Bicarbonate reactions- Coldness, thickness





Water and Calcium Cloride- heat, smells like chlorine





Phenol Red and Calcium Cloride- hot, smells like rubing alchohol





Phenol Red and Sodium bicarbonate- coldness, thick liquid, no smell





Sodium Bicarbonate, Calcium chloride, and Phenol Red- yellow paist, expanding











1. Water and Sodium bicarbonate made it cold, while the Phenol Red and the Calcium Cloride made it hot.





2.no because in the overall mixture we had the heat and the coolness.





3. the overall mixture produced a yellow paste. the chemicals responsible for the color change were sodium bicarbonate, calcium, and phenol red.





4. yes because to change from a liquid to gas you need a temerature change.





5. the solid chemicals will no nothing without one of the liquids.





6. a new chemical is produced because there is a phisical looking change. either of the liquids combined with either of the solids.





7.
