How can you use soap in Suminagashi?
It will push the colors around and allow them to spread out more, which will create more of a marbled pattern.
What does the hair on the Water Striders legs do?
The hair stops them from sinking and doesn’t break the surface tension.
What is the difference between anions and cations? What are some ways to remind you which one is which?

What is the compound name for ZnS?
Zinc Sulfide.
What is electronegativity?
Electronegativity is the ability of an atom to attract other electrons and become slightly more negative.
