Key Questions

• How can compounds be broken down?

  There are certain processes to break down a compound
  It is possible through chemical means
  One of them would be electrolysis, which breaks down the compound #H_2O# into hydrogen and oxygen
  You might have seen this in school, if not check it out on youtube
  Anyways, hope this helped
