What is photosynthesis? identify the reactants, the products, and where the process takes place in a cell.

Photosynthesis is the process of turning light energy into chemical energy. The process takes place in a place called chloroplast.

Reactant: Carbon dioxide, water(H20), Light (Radiant)energy.

Product: Glucose and oxygen.  

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.
