neutralization rxns + ocean acidification stuff
With an increase in system pressure, what happens to the shift?
Shifts towards fewer moles of gas.
Acid means lower or higher pH than 7?
Less than 7.
2Al(s) + 3CI2(g) —> 2AlCI3(s). We have 35.9g AlCI3. If calculating for grams of CI2, what's your starting and ending town?
Massfield for both.
What is a double displacement reaction?
A reaction where two elements "switch partners".
Write name for N2O4.
Dinitrogen Tetroxide.
With an increase in a substance concentration, what happens to the shift?
Shifts away from substance.
Calculate pH for a neutral solution.
7, as it neutral will always mean 7 pH.
You have 0.7 moles of sodium chloride dissolved in 4.5 liters of water. Calculate molarity.
0.155555556.
What is a single displacement reaction?
One where an element takes the place of another.
Write chemical formula for hydrogen peroxide.
If a substance is amphoteric, what does that mean?
It can behave as an acid or a base.
What happens to pOH when it increases 6-9?
It becomes more basic.
What is a limiting reactant?
The reactant you have the least of.
Ca(OH)2 + HCl -> CaCl2 + H20. Write Mole Ratio.
1: 1: 1: 1
The prefix for 2 is...
Di
N2(g) + 3H2(g) <-> 2NH3(g). H=-92 kj. Disturbance is lower pressure. Left or right equilibrium shift?
Left equilibrium shift.
Ca(OH)2 + HCl -> CaCl2 + H20. Label BLB, BLA, CA, CB, ACBP, BCAP.
BLB, BLA, CA, CB respectively.
BLB + CA = BCAP.
BLA + CB = ACBP.
Limiting reactant is the reactant that you have the least of. True or False?
False
N2(g) + 3H2(g) <-> 2NH3(g). Write Mole Ratio.
1:3:2
The prefix for 5 is...
penta
N2(g) + 3H2(g) <-> 2NH3(g). H=-92 kj. Disturbance is lower NH3. Determine Equilibrium Shift, and higher/lower for H2, NH3, and N2.
Equilibrium Shift = Right, N2 = lower, H2 = lower, NH3 = Higher.
Base means higher or lower pH than 7?
Higher pH than 7.
If a hamburger requires 2 buns, 1 patty, and 3 pickles, and you have 5 buns, 3 patties, and 70 pickles, what is the limiting reactant?
The buns.
You have 0.7 moles of sodium chloride dissolved in 4.5 liters of water. Calculate molarity.
0.155555556.
Write chemical formula for Sulfur Dioxide.
SO2.
