Solutions/ rxn
Whats is a limiting reagent and what would be considered the baseline unit to determine this
the chemical with the least moles relative to the balanced equations...moles
What is the difference between dissolving and disassociating
disassociating means ionizes where as dissolving blends with solution without changing original compound
Name a binary acid, include prefix and suffic...hint same for all binary
(binary is two elements no oxygens)
Hydro______ic acid
Example what OIL RIG (LEO the lion GER) is and stands for
Oxidation is Loss , Reduction is Gain
Loss electrons Oxidation, Gain electrons Reductions
what are the ABC's of gas laws (first 3 learned )
Avogadro's V/n=V/n
Boyle's PV=PV
Charles's V/T=V/T
what are the stoichiometric similarities in finding the amount of products formed and reacants required
the limiting reagent always goes first with just different molar ratios from the given or determined equation
what are some hints a reaction will not react?
both compounds are made up of ions from strong bases and acids...other answers are acceptable
naming oxyacids in all cases
XO
XO2
XO3
XO4
hypo___ous acid
_____ous acid
____I️c acid
per_____ic acid
How would you assign redox values to:
free elements
free ions
polyatomic ions
free ele= zero
free ions= charge
poly= set equal to charge and solve algebraically
what's the father equation of gas laws and what does that mean
ideal gas law and other reactions can manipulate the law to become and of the ABC's or adhere to whats given.
What is molarity and how would you find it given grams of a solute and mL of solution
convert to moles and L
What is a net ionic reaction and how does it differ from molecular or complete ionic
only includes ions that will react and the solid or gas they form, excludes spectators
what the pattern for strong bases on the periodic table?
bonus for a way to remember acids
zigzag between alkaline metals and alkaline earth metals
(mine is HI Br NO3 SO4 Cl ClO4)
What is an oxidizing agent compared to what is being oxidized
the oxidizing agent is what induces oxidation by accepting electrons
What are the postulates of Kinetic Molecular Theory
2. particles are so small assume volume is negligible
3. pressure is caused by particle collision
4. no loss of energy during collision
5. Avg KE is proportional to temp
(KE=1/2 mv^2
What is the dilution equation and what is it comparing
M1V1=M2V2
comparing moles
(think shot compared to cocktail)
What are the differences strong, weak, and nonelectrolytes
ionize 100%- strong
ionizes 5% or less - weak
may dissolve but not disassociate- non
Way to determine weak acids
longer chains and more carbons
they key the same oxidation state the whole time and can be disregarded after finding charges
what is rms speed
(3RT/MM)^1/3
MM= molar mass in kg
R= 8.314
how many mL of 2.5M of NaOH does it takes to make 525mL of 0.150M of NaOH
Check Calculations...I️ got 31.5 mL
CoCl2(aq) + Na2SO4(aq)
write net ionic
none, no reaction all spectators
Explain the key point of titration, what is it, when is it done and what does that mean
neutralizing an acid with a base to the equivalence point, which is equal OH moles to H moles
Zn + H2SO4 = ZnSO4 + H2
whats being oxidized
the Zinc
they have different velocity meaning lighter particles travel faster...key part of diffusion
