NS: This is a chemical change and we know that because the new substance that was formed. This is called the Elephant Toothpaste. There is 10% Hydrogen peroxide, food coloring, soap and yeast in this chemical reaction. When they are added a new substance is formed which they call Elephant Toothpaste. When the yeast is added at the end, the new substance is formed. It is also very hot so there is a temperature which also proves it is a chemical reaction.

NS: This is a chemical change and we know that because the new substance that was formed. There is sugar and caustic soda solution plus the Potassium permanganate solution. The potassium permanganate solution was purple but changed colors over time when it reacted with the sugar and caustic soda solution. The color change proves that a new substance was formed

C: This is a chemical change and we know that because the color change. Potassium iodine, water and soluble potato stash. Solution of these mixed is white and cloudy. Then they put in another beaker hydrogen peroxide. When solutions are added there is a color change and in this example it becomes blue.
