Question

Evidence of chemical reactions include -

light production, color change (new/different), gas production (bubbles/fizzing - not boiling), precipitate, and temperature change



no light production, color change (new/different), gas production (bubbles/fizzing - not boiling), precipitate, and temperature stays the same



color change (new/different), gas production (like when a soda is opened), precipitate, and temperature stays the same



light production, color change (like adding food coloring to water), gas production (like when a soda is opened), precipitate, and temperature change

Answer 1

light production, color change (new/different), gas production (bubbles/fizzing - not boiling), precipitate, and temperature change

Step-by-step explanation:

whenever there is a chemical change, there is always bubbles, fizzing.

hope it helps.

Answer 2

I think it's light production, color change (new/different), gas production (bubbles/fizzing - not boiling), precipitate, and temperature change
