Homework Answers
From the periodic table it can be said that each colour indicate the following elements:
Green : Nitrogen
Blue : Phosphorus
Red : Sulphur
Purple : Chlorine
Yellow : Argon
So, Purple : H3XO4 : H3ClO4 known as trihydroxy chlorane oxide
Red : No match, but it can be H2XO4 = H2SO4 known as sulphuric acid
Green : H2XO4 : H2NO4 known as nitrate hydrate
Blue: HXO3 : HPO3 known as metaphosphoric acid
Yellow : HX : HAr or ArH know as argon monohydride.
