You'll be able to retake this formative as many times as you like. The questions won't be counted for points but you'll see the correct answers every time you answer. For the drawings you do, look at the hint to check your work.
Good luck!
Many of the molecules we're studying at made only of hydrogen, carbon, and oxygen. What is the order of these elements shown in the molecular formulas?
To write subscripts in formative.com, click and hold on the image that looks like this in each answer field:
