How do you name binary molecular and ionic compounds?
What is: (molecular) Start with the first element, second element always ends in -ide, prefix attach to front: depend on # of atoms for each element in the compound. (ionic) cation always goes first- name of that element, and anion always goes second which ends in -ide

How do a convert from moles to mass?
What is multiply by the molar mass
100
What are the molecules/atoms on the left and right side of the arrow called? What do the numbers in from of them represent
What is reactants and products. The amount of moles of that molecule/element
100
Explain how to go from percent composition to a empirical formula
What is first assume the sample is 100g, find the moles for each element, take the smallest mole amount and use it as a ratio for all the other elements, and write the empirical formula with these ratios
100
What is the limiting reactant?
What is the reactant in a chemical equation that limits the amount of product that can be formed
200
How do you name binary compounds with transition metals?
What is when naming, have to include oxidation # as a roman numeral, with the same naming as ionic compounds
200
How do I convert from moles to atoms?
What is multiply by Avogadro's number
200
What are the products and reactants of a combustion reaction
What is reactants are hydrocarbons and oxygen and products are carbon dioxide and water
200
How do you go from an empirical formula to percent composition?
What is first find molar mass of each element with its atomic mass (using the number defining how many moles there are), then find the total molar mass of the molecule, use the mass of elements divided by the total molar mass to find the percent composition
200
What is the excess reactant
What is the reactant in a chemical equation that remains when a reaction stops when the limiting reaction is completely consumed
300
Explain the old convention of transtion metals
What is the lower oxidation number has -ous ending, and the higher oxidation number has -ic ending (ferrous, ferric). Basically memorize these
300
How do you convert from mass to moles?
What is divide by molar mass
300
What are the steps to balancing equations (based on your notes)
What is write out the equation, make a table for the molecules, determine what is unbalanced, balance the equation
300
How do you convert from empirical formula to molecular (given molar mass of molecule)
What is divide the molar mass of molecule given by the molar mass of the empirical formula. Use this number (the ratio) and multiply the empirical formula by it

Name MnO4-
What is permaganate

Name HClO, HClO2, HClO3, HClO4 and what are these?
What is hypochlorous acid, chlorous acid, chloric acid, perchloric acid. These are acids
400
How do I convert from atoms to moles?
What is divide by Avogadro's number

CO2 + H2O --> C6H12O6 + O2 and what type of reaction is this?
What is 6,6,1,6. photosynthesis reaction
400
How do you go from molecular formula to empirical formula (given mass of empirical formula)
What is first find the molar mass of molecular formula. Take this mass and divide it by the empirical formula mass (This is a ration). Take this number and divide it by the molecular formula element numbers
400
name the prefixes from 1-10
What is mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca
500
Name the 2 nitrogen based polyatomic acids with their formula
What is Nirite (NO2-) and Nitrate (NO3-)
500
What is the difference in molar mass between empirical and molecular formulas
What is empirical mass is based on the simpilest form (Na2Cl6 vs. NaCl3)
500
Balance C2H6 + O2 --> CO2 + H2O. What is this type of reaction?
What is 2,7,4,6. Combustion reaction
500
What is the percent composition of each element in NaOH
Na- 22.99g/mol
O- 15.999g/mol
H- 1.008 g/mole
What is 57.5%, 40.0%, and 2.5%
500
What are the steps to use something as the limiting reactant
What is first convert grams given (of reactants) to moles, determine which reactant is the limiting reactant, use ratio to find how many moles of the product wanted can be produced with the limiting reactant, convert to grams
