100
Usually atoms, molecules, or ions
Representative Particles
100
reactants --> product
Chemical Reaction
100
The smallest particle of an element that retains its identity in a chemical reaction.
Atom

 6.02 x 1023  

Avogardo's Number 
200
Standard Temp is 0 degrees Celsius 

 or 1 atmosphere (atm)

STP (Standard Temperature Pressure)
300
Undergoes change in a chemical reaction 
Reactant 
300
equals to 1/12 the mass of a carbon-12 atom 
Atomic Mass Unit 
300

2 mol H2 : 1 mol O

Mole Ratio
300
A substance produced in a chemical reaction.
Product
300

 Mg (24.31 g)+ C (12.01 g) +O 3(16.00 g) = 84.32 g

Formula Mass
400

V1/n1 = V2/n2

Avogardo's Hypothesis
400
A substance that increases the rate of reaction by lowering the activation-energy barrier; the catalyst is not used up in the reaction.
Catalyst
400
the percent by mass of each element in a compound
Percent Composition 
400
Double Points!

They are sufficient to react with each other, first used up in a chemical reaction and remains after the reaction.

Excess/Limiting Reagent 
400
A specific number of water molecules bound to each formula unit.
Hydrate
500
Double Points!

The substance is totally consumed when the chemical reaction is complete, and then remains when a reaction stops when totally consumed.

Limiting/Excess Reactant 
500
The smallest yield of product.
Theoretical Yield
500
The amount of product that forms when a reaction is carried in the laboratory.
Actual Yield
500

It is calculated to be the experimental yield divided by theoretical yield multiplied by 100%

Percent Yield
500
A formula with the lowest whole number ratio of elements in a compound
