36 colored paper clips (12 each of 3 different colors)
1.Each paper clip represents a single atom. Designate a different color of paper clip to represent atoms of oxygen (O), hydrogen (H), and carbon (C). Makes two molecules each of hydrogen (H2) and methane (CH4) and six molecules of oxygen (O2).
2."React" on H2 with one O2 by splitting the molecules and joining one oxygen atom to two hydrogen atoms. Because there is a unreacted oxygen atom, you must react it with another hydrogen molecule to form a second water molecule.
3.Summarize what happened in this reaction by placing the number of each molecule reacted or formed in front of its formula.
___H2 + ___O2 ---> ___H2O
So what's the question? What don't you understand?
