Re: How to tell which elements will be most likely to form a covalent bond
usually a metal and nonmetal forms ionic bond, other circumstances usually form covalent bonds

Re: cation vs anion
Cation is positive, which means the atom lost electrons. Anions are negative, which means the atom gained electrons.

Re: Metals
Its one of the properties for metals to lose electrons more easily than gaining

Re: Test 2 final question [ENDORSED]
Is there an explanation why the ratio is one to one or it's just a phenomenon that's being observed?

Re: Wavelength [ENDORSED]
I believe we dont have to remember all the frequencies, but we probably need to remember the order of the frequencies.

Re: Isotopes [ENDORSED]
Elements exist in different forms. While they all have the same amount of protons in one atom, the number of neutrons in them is different. Every kind of variation of the neutron numbers is an isotope.

Re: Molarity [ENDORSED]
Not necessarily, it all depends on the volume. Molarity is the raito of the number of moles and the volume of the solution.

Re: Finding Molecular X
In the case of the example you mentioned, you need to figure out what will be produced as the result of the reaction just by the properties of the reactant you are given.

Re: Different ways of determining limiting reactants
The best way is probably to get the moles of the ingredient and divide them by the coefficient in front of them in the chemical equation, then compare which number is the smallest to determine which is the limiting reactant
