What is Avogadro's number
100
This is the formula with the smallest whole mole ratio of the element
What is an empirical formula
100
This is a compound that has a specific number of water molecule bound to its atoms
What is a hydrate
100
This term is the study of quantitive relationships between amounts of reactants used and produced formed by a chemical reaction
What is Stoichiometry
200
This uses formulas rather than words to identify the reactants and the products when it hasn't been balanced yet.
What is Skeleton Equation
200
~ a ___ is a unit or have you heard? Its 6 times 10 to the 23rd ~
What is a mole
200
This term specifies the actual number of atoms of each element in one molecule or formula unit of the substance
What is molecular formula
200
This is how you name a hydrate
What is a compound that follows a dot and uses prefixes according to the number of H2O molecules
200
This term refers to a ration between the numbers of moles of any two substances in a balanced chemical equation
What is mole ratio
300
Step 1: Write the skeleton equation Step 2: Count the atoms of elements in the reactants and the elements in the products Step 3: Change the coefficients to make the number of atoms of each element equal on both sides Step 4: Write the coefficients in their lowest possible ratio These are the steps for doing this
What is Balancing Equations
300
This term refers to the percent by mass of each element in a compound
