Classifying Reactions
Two or more reactants combine to make 1 new product.
What is Single replacement?
An equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products.
What is balanced equationing?
6.02 X 10^23
What is Avogadros Number?
the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers.
What is stoichiometry?
Song title of ms.pendergrass song
moly stop
A single reactant breaks down to form 2 or more products.
What is Decomposition?
No information about the relationship between products and reactants can be derived.
Non-Balanced equation
Molar mass of Li₂S
39.01 g/mol

Holy moly cheat sheet
A single element replaces a similar element of an adjacent reactant compound.
What is single replacement?
Steps to Balancing chemical equations
Convert the mass of each element to moles using the molar mass from the periodic table.
What is Step 1
the reactant that limits the amounts of the other reactants that can combine and the amount of product that can form in a chemical reaction
what is limiting reactant
the amount of product that could form during a reaction calculated from a balanced chemical equation; it represents the maximum amount of product that could be formed from a given amount of reactant
what is theoritical yield
Two ionic compounds exchange ions, producing 2 new ionic compounds.
What is Double Replacement?
Balance the equation: Fe+ Cl2 −−→ FeCl3
2 Fe+3 Cl2 −−→ 2 FeCl3
round to the nearest whole number. This is the mole ratio of the elements and is.
What is step 4
the substance that is not used up completely in a reaction
what is Excess Reactant
smallest part of an element that can be identified as that element
what is an atom
A single element or compound combines with oxygen gas releasing energy. This rapid oxidation is called burning.
What is Combustions?
Balance the equation: C5H8O2 + NaH+ HCl −−→ C5H12O2 + NaCl
1 C5H8O2 +2 NaH+2 HCl −−→ 1 C5H12O2 +2 NaCl
What is step 3
the ratio of the actual yield to the theoretical yield multiplied by 100
Percentage Yield
substance that CANNOT be chemically broken down into simpler substances
