Count the total number of atoms in h 2 o: 2 3 4 5 6

The total number of atoms is 3.

Make sure to not confuse elements with atoms. Elements are substances used in a chemical equation that cannot be broken down. There are two elements in H2O: hydrogen and oxygen.

Atoms in the compound is the number of elements. Hydrogen would be one atom, but since it has a subscript of 2, it would mean that there are two hydrogen atoms.  Oxygen is another atom, however, it does not have a subscript. Don't make that fool you because there is actually a subscript which is the understood one. That is why there are three atoms.

Hope this helps!!!

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
