What is the equation for molarity
|
Molarity= moles of solute/liters of solution
|
|
|
What is the equation for molality
|
Molality = moles of solute/ kg of solvent
Molality is independent of temperature |
|
|
What is the relationship between temperature and solubility, concerning solids and gas
|
Increase temp, where solid in liquid and then the solubility will increase
Increase temp, where gas in liquid and the solubility will decrease Increase pressure and increase solubility |
|
|
What is the equation for a mole fraction
|
Mole fraction equals= moles of solute/ moles in solution
|
|
|
What are the solubility rules
|
(I)
All compounds containing alkali metal cations and the ammonium ion (NH4+) are soluble. II. All compounds containing NO3-, ClO4-, ClO3-, and C2H3O2- anions are soluble. III. All Silver(Ag+) lead(Pb 2+ /Pb 4+) and mercury (Hg2 2+/Hg 2+) are insoluble |
|
|
The oxidation states of the following
Metals- F- O- H- Halogens- Oxygen Family- Nitrogen Family- And remeber the top takes precedence What does Hydride mean |
Metals- Group1 (1+) Group (2+)
F- -1 O- -2 H- +1 Halogens- -1 Oxygen Family- -2 Nitrogen Family- -3 Hydride means the Hydrogen is negatively charged |
|
|
What do the endings of the oxidation states for monoatomic states mean...for example "ic" means___ and "ous" means____
|
Ic takes the higher oxidation state
Ous takes the higher oxidation state Example -Fe Ferric means (3+) Ferrous means (2+) |
|
|
What do the endings of the oxidation states for polyatomic states mean...for example "ite" means___ and "ate" means____
|
Remember "ate more" ate takes the higher oxidation state
|
|
|
What is the oxidation states of the atoms in NaBH4
|
Na is +1
B is +3 H is -1 |
|
|
Which of following do you NOT do rates with AND why :
Gas Liquid Solid |
Gas and Liquids because their volume doesn't change
|
|
|
In the way Chris taught how to do the "old school (one with reactant and products in the rate equation)" reactant equation what goes on the top and the bottom
|
The bottom recieves that reactant coefficent
The top recieves the product coefficient The reactant always get the negative |
|
|
Just remember only the part of the rate determining step is part of the rate law expression
|
Just remember only the part of the rate determining step is part of the rate law expression
|
|
|
What are the properties of the rate law
|
Only the reactants included
Doesn't have to be reversible n,k must be determined experimentally Exception-from an elementary step |
|
|
From the reaction what is the catalyst
A + B - C C + F - E + A Overall reaction B + F - E |
The catalyst is A because it is regenerated at the end of the reaction
|
|
|
What is the arrehenius factor and what equation is the A factor involved in
|
K= Ae ^(-Ea/RT)
The Arrhenius factor is a measure of succesfull colisions Ea-Activation Energy R-Constant T-Temperature |
|
|
Show how increasing temperature has an effect on Ea
|
Increasing Temp= Increase KE= Increase Arrhenius factor = Increase the successful collisions and this lowers activation energy
|
|
|
What needs to occur for precipitate to form?
|
You need to exceed the Ksp
|
