What is a chemical change explain with example?

The bubbles of gas that you observed form when an antacid is dropped into water is an example of change. Another clue that a chemical change has occurred is the formation of a solid. A solid that separates out of solution during a chemical change is called a precipitate.

What are 3 differences between physical and chemical changes?

A chemical change is a permanent change. A Physical change affects only physical properties i.e. shape, size, etc. … Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. A few examples of chemical change are digestion of food, burning of coal, rusting, etc.

Is baking a cake a chemical change?

As you bake a cake, you are producing an endothermic chemical reaction that changes ooey-gooey batter into a fluffy, delicious treat! … Heat helps baking powder produce tiny bubbles of gas, which makes the cake light and fluffy. Heat causes protein from the egg to change and make the cake firm.
