What are the names of HBr and HNO3? They follow different naming rules. Why?
HBr: Hydrobromic acid.
HNO3: Nitric acid.
HBr is a binary acid made of hydrogen and a nonmetal. The naming rule is:
hydro-(nonmetal root name)-ic acid.
HNO3 is an oxyacid made of hydrogen and a nonmetal+oxygen. The naming rule is:
(nonmetal root name)-ic acid

What does it mean if a reaction yields "NR"
What is "No Reaction" as the reaction is not possible. For example,
Cu (s) + ZnSO4 (aq) yields NR
This is because the copper is not reactive enough to push either Zinc or Sulphate from reacting with each other so it sits on top and no reaction will occur.

Mercury is multivalent, two of it's possible forms are mercury (I) and mercury (II). An example of a compound is mercury (I) chloride: Hg2Cl2. Why isn't this compound's formula simplified to HgCl? What type of bond is preventing this?
Mercury (I) is made of two mettalically bonded mercury atoms, each with a 1+ charge! Therefore, mercury (I) appears as Hg22+, and the atoms cannot be separated or simplified. So, to follow the octet rule while also keeping both mercury atoms, the formula of mercury (I) chloride must be written as Hg2Cl2.
