An example of a chemical formula is the formula for water, H2O. Notice that the subscript under the Hydrogen means that there are 2 atoms of hydrogen and no subscript under O means that there is one atom of oxygen.
I want you to create a chemical formula for the molecule below. Do not forget the subscript(s). This question is worth 3 points.

Wonderful, I am starting
ok
I am going to get an A, bet!!!
Great
The subscript is the number below the base line of an atom. For example, the subscript for H, which is Hydrogen, in the molecule CH4 is 4 it means that...
1 Point
There are 2 Hydrogen (H) atoms in CH4
There are 4 Hydrogen (H) atoms in CH4
There are 4 Carbon (C) atoms in CH4
There are 2 Carbon (C) atoms in CH4
What does it mean if the is no subscript. For example, in CH4, carbon (C) has no subscript under it. This means...
1 Point
that there are no atoms of Carbon (C) present in the molecule
that there are 4 atoms of Carbon (C) present in the molecule
that there is only one atom of Hydrogen (H)
that there is only one atom of Carbon (C)
