I need help asap! :) Given the following balanced equation for the electrolysis of melted aluminum oxide to produce aluminum and oxygen: 2Al2O3 --> 4Al + 3O2
What is the molar ratio of
aluminum oxide to aluminum ?
aluminum oxide to oxygen?
aluminum to oxygen?
Write your answer as a fraction, example 4/8

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.

let that person have a turn to speak : )
