What is the difference between molecular and empirical formulas 

Empirical formulas is the ratio between the the actual amount of atoms in a molecule, while the molecular formula is the actual amount of atoms in a molecule

100

What is Avogadro's number and what is it other name 

a mol and it is 6.022 * 1023

100

What are the 4 steps for balancing equations

Put a 1 in front of the biggest molecule

Balance the rest of the equation base on that molecule

If there is a roadblock double the whole equation

Balance the smaller molecules last. 


100

What is the solution map for chemical equations mass converions

mass A -> mol A -> mol B -> mass B

100

What is the name of the compound

HBr

hydrobromic acid

200

How do you name Ionic bonds, main groups and trans groups

For the main group, put the cation(metal) first followed by the base name of the anion and add the -ide if its off the table. For Trans group to do the same but you put the roman numeral behind the metal that match the charge.

200

How do you convert from mass to moles

molar mass or the atomic mass of the element

200
What elements or polyatomic are always soluble

Li, Na, K, NH4, NO3, C2H3O2

200

What is a limiting reactant 

the reactant that limits the amount of product that you can make 

200

Name the compound 

FeO

Iron (II) oxide

300
How do you name covalent bonds
full name of the nonmetal that follows the prefix that match the subscript then the base name of the nonmetal that follows that match the subscript and followed by ide 
300

The chemical formula gives you a relationship between what 

moles of substances

300

What are the 3 types of equations 

Molecular, complete ionic, and net ionic 

300

What is theoretical yield 

the amount of product that can be made in a chemical equation base on the amount of the limiting reactant

300

How many atoms are in 2 moles

12.044*1023

400

How do you name Binary acids

How do you name oxyanion acids

hydro+ base of element name+ ic

(-ate) = the base name of the element + ic

(-ite)= the base name of the element + ous

400

How do you calculate the mass percent

mass of 1 mol of the element times the subscript/ mass of 1 mol of the compound
400

What are the 3 types of reactions

acid-base, gas evolution, Oxidation-reduction, and Combustion

400

How do you find the percent yield 

(ty/ay)* 100%

400
