Chlorine, Uranium, Osmium, anything from Sulfur on really has 16 protons.
H2 is colorless and odorless
NO2 is brown, pungent, and toxic
I am taking the same test ;)
1.) Single-displacement
AB + C --> AC + B
2.) Double-displacement
AB + CD --> AD + CB
3.) Synthesis
A + B --> AB
4.) Decomposition
AB --> A + B
Hope this helps!
