4. Evidence of Chemical Changes
Change of color
Change of odor
Formation of a gas
Formation of a precipitate
Change in heat or energy

5. 3 Things to Remember The 5 evidences of chemical changes
Iodine is a brown substance. Any shade of brown is not a color change.
Going into solution is not a chemical change.

10. Vinegar & Baking Soda NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
Baking Soda + Vinegar →
Sodium acetate +water + carbon dioxide gas

11. Iodine & Cornstarch
C27H48O20+ I2 → (I2 + I3) + C27H48O20
