5examples of each chemical properties, physical properties, chemical changes, and physical changes.

Examples of chemical changes are burning, cooking, rusting, and rotting.

For example;

Burning wood

Souring milk

Mixing acid and base

Digesting food

Cooking an egg

Examples of physical changes are boiling, melting, freezing, and shredding.

For example:

Crumpling a sheet of aluminum foil

Melting an ice cube

Casting silver in a mold

Breaking a bottle

Boiling water

Physical properties are properties that can be measured or observed without changing the chemical nature of the substance. Some examples of physical properties are:

color (intensive)

density (intensive)

volume (extensive)

mass (extensive)

boiling point (intensive): the temperature at which a substance boils

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
