 * What is a covalent bond?
 * What is an ionic bond?
 * List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.).

 * 1) A Covalent Bond is bond between at least 2 nonmetals that share electrons.
 * 2) An Ionic Bond is a bond between at least 1 metal and 1 nonmetal that transfer electrons.

 * I got the name of is formula, which happens to be an acid (H+), from todays lesson. I knew it was an acid because it started with hydrogen. In rule 3 of an acid; if the next element ends with the suffix -ate the ending changes to -ic followed by the word acid.
 * I got the formula of dichlorine monoxide easily. I know that in chemistry if a name has a prefix it would be a covalent bond. The 2 prefixes are di- and mono-; di- means 2 and mono- means 1 so the formula would have 2 chlorines and 1 oxygen atom.
 * In this name there are roman numerals, (II), which means that zinc is a transition metal with 2+charge. Then the 2nd element has the suffix -ate so it must be a polyatomic element. Looking at the graph of polyatomics, phosphate has a 3-charge. So I crossed the charges to of the 2 elements and got the formula.
 * This is an acid. The prefix of the acid is hydro- and the suffix is -ic, and these tell me that the hydrogen atom is bonded to a single nonmetal. In the name it says sulfur so hydrogen is bonded to sulfur. Then I just crossed charges to get the formula.
