When 1.5 grams of magnesium burns, how many grams of magnesium oxide will be formed?

a. write a balanced chemical equation for the above reaction.

b. show by unit conversion (show conversion factors, ie. 2 g h20 x 1 mole h2o/18 g h2o x x = answer?

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.
