The individual components of a solution

I think The substances that make up a homogeneous solution are called components of the solution. It has basically has two components i.e. a solvent and a solute. Solvent: The component of a solution which dissolves the other component in itself is called solvent.

Explanation:

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.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
