Helps Predicts Reactions #

Thermodynamics

Helps you know which bonds are broken and formed # # # #

Derminers if its exo or endothermic

Solubility # #

Like Dissolves Like

Strength of the forces # #

Can be used to determine sponteniety

Determines what type of bond is formed

Can be used to calculate the equilibrium constant

Molarity is Used in Acid Base

Solutions #

Electrochemistry

Used to Calculate moles in a reaction #

Couolums Law

The greater the radius the more soluble

Solubility

If it is easily soluble then it is spontaneous

And it is product favored

How easily an atom is willing to accept an electron #

This determines the properties of the substance

Its Solubility

Melting and Boiling Point

Used to calculate the enthalpy and spontaneity

Determines if the reaction is spontanous

Determines if the reaction is product or reactant favored #

Predicitng a reaction allows you determine if the entropy of a reaction.

Knowing the entropy of the reaction you can calcuate delta G

Helps you find the Element quickly #

Lets you know what energy level the element is on

Helps you identify the element quickly

Can Help you know certain properites of the element # #

Elements in the same groups have similar properites #

Properties tend to get more extreme as you move down a period
#

Helps you know the number of valence electrons in the element
#

Elements from the same group share the same number of valence electrons
#

Molarity is used in beers law

Molarity is important for absorbance calculations

can help you determine what type of bond is formed between two molecules

Can help you determine which bonds are broken and formed
#

Helps with enthalpy calculations

Can be applied to solutions

know solubility

If it was polar it would dissolve in polar substances

If it is non polar it would dissolve in nonpolar substances

Determines the electron geometry

Determines the molecular Geometry

Helps you know the bond angles of the molecule #

Structure of the molecule is affected by lone pairs

Structure would determine what type of intramolecular forces are present
#

This could be used to compare which of two elements may have a stronger attraction

Determine which has a higher boiling point

Determine which has a lower freezing point

Calculating the molarity

This can be used to calculate the equilibrium constant

Use the Concentrations of Products over Reactants to calculate Keq

Can Also be used to calculate Q

Determines where the equilibrium would shift to produce more of product or reactant depending on K and Q values


Can be used to calculate order

Use Molarity to determine the order of the reaction

Use the order of reaction and concentrations to calculate the rate constant

We can then use the rate constant to calculate the half life of a particular substance

Knowing the rate constant we could also determine what order the reaction is when given the graph

Knowing which subshell will help you write electron configuration
# #

This can be used to determine if the element is in the ground state or excited state

If an element is in its excited state the electron configuration
would be a half filled d and s orbital for a transition metal

Can help you know the properites of the bond formed #

If there is a large electronegativity difference then it may be an ionic

If the electronegativity difference is large but not large enough to completely remove the electron then it may be a dipole covalent

Could be a evenly shared covalent bond if the electronegativities of the two atoms are similar or equal

Balancing Equations

Stoichometry

Finding Percent Composition

Can be used to find limiting reagent

can be used to find what is in excess

can be used to calculate how much of a product is produced

importnat conept for combustion analysis

helps determine the molecular formula #

helps determine the empirical formula #

Can be used in gravimetric analysis

Helps determine which compound was initially reacted and precipitated using the percent composition

Helps balance redox reactions #

Helps determine how many moles of electrons were transferred
#

This is key to doing electrochemistry porblems

Knowing moles of electrons allows you to calculate time the reaction was run
#

How many g of the initial substance were present

How many electrons were transferred as a whole

Use to figure out electron configurations #

Number of protons, neutrons, and electrons # #

Number of subshells

Used to figure out number of moles #
