What are the prefixes of 1,2,3,4,5 in covalent compounds?
mono, di, tri, tetra, penta
what is the formula for silicon tetrachloride
SiCl4
When do you use the suffix ic and ous when naming acids?
If ends with ate it gets replaced with ic and when it starts with ite it gets replaced with ous.
Is O2 polar or non-polar
non polar because they are the same element
Which sort of element does most covalent bonds form?
Non-metallic elements
What are the 3 steps to naming binary molecular compounds?
1. first element always comes first with its full name
2.second element comes next. you must write the root of the element followed by ide at the end
3. use prefixes in front of the element names when needed

What is the molecular compound name of NF3?
nitrogen triflouride
What is the formula for dinitrogen tetrahydride?
N2H4
What acid has the formula HI.
hydroiodic acid
Is CF4 nonpolar or polar?
nonpolar because the fluorine is symmetrical on all sides
What type of bond is the strongest, a single bond, double bond, or a triple bond? Why?
A triple bond is the strongest because the more bonds the shorter they are. Shorter bonds equal stronger bonds.

arsenic hexoxide
What is the formula for ammonia?
Ammonia also called nitrogen trihydride's formula is NH3.
What acid has the formula H3BO3?
boric acid
Is NH3 polar or nonpolar?
Polar because there is an imbalance in electronegativity.
