Is it true or false that science is a collection of facts that does not evolve. we have gained all the knowledge we can from science.

False

Science also comprise of "theories", which are not proven (not facts), such as the Big Bang Theory, and Evolution, which has no ground work, and is all but rubbish. While some science are concrete, with facts in place, some other parts are questionable.

hope this helps

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

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.
