I know a chemical reaction has happened because the  red liquid starts fizzing over the top of the glass.

This evidence shows a chemical reaction because it fizzes which is part of F.A.C.T.S.S.

I know a chemical reaction happened because a color is on the nails and a new substance called rust appears on the surface of the nail.
Fe2O3 is this compound formula.
This evidence shows a chemical reaction because their is a new compound called Iron-Oxide that is on the nail.]]> 2018-02-22 19:46:19 UTC https://padlet.com/ethanlesser2022/ge6deyze3ung/wish/234453093 Temperature ethanlesser2022 https://padlet.com/ethanlesser2022/ge6deyze3ung/wish/234456539 Example: Burning Wood
I know this was a chemical reaction because  the wood changes to ash which is a temperature change. It is a exothermic reaction which means it gets hotter.

This evidence shows a chemical reaction because it creates new substance like ash and carbon dioxide]]> 2018-02-22 19:51:09 UTC https://padlet.com/ethanlesser2022/ge6deyze3ung/wish/234456539 Solid ethanlesser2022 https://padlet.com/ethanlesser2022/ge6deyze3ung/wish/234862675 Example: Adding Magnesium Sulfate to water
I know this is a chemical reaction because you add to liquids to each other and they form a solid.
MgSO4+ H2O

This evidence shows a chemical reaction because the two substance form a solid called magnesium sulfate heptahydrate.

I know this is a chemical reaction because the heat while baking a cake reacts with the baking powder used in a cake.

This evidence shows a chemical reaction because the two substances form a cake.

I know this chemical reaction has happened because the banana rots and gives off a bad odor.

This evidence shows a chemical reaction because oxygen reacts to the polyphenol oxidize enzyme in the banana.]]> 2018-02-23 19:35:25 UTC https://padlet.com/ethanlesser2022/ge6deyze3ung/wish/234873536
