Acompound is made up of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. which of the following chemical formulas represents this compound?

Since Carbon has a chemical name of "C," Hydrogen has "H" and Oxygen has O, we can start with the name "CHO". After this, the next task is to place the proper numbers next to the proper elements. In this case, the representation would be C(6)H(12)O(6), which would be the representation of the simple sugar glucose.
