Le Chatelier's Principle/Ocean Acidification/Antacid Neutralization Rxns
What does the Le Chatelier principle say about a reaction?
When something is done to a reaction, the reaction will respond in the opposite way.
What is the difference between a weak base and a strong base?
A weak base doesn't fully dissolve whereas a strong base does.
What does BLA pair with? What does BLB pair with?
BLA + CB
BLB + CA
How many compounds are displaced in a double displacement reaction?
Two compounds
What type of bond is H2O?
Polar covalent bond
What is a neutralization reaction?
A reaction where an acid and base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.
What pH levels are considered acidic?
pH of 0-6.9
Does BLB gain or lose?
Gain
What is the difference between a solvent and solute?
Solvent: Substance that dissolves the solute
Solute: Substance that is being dissolved
Which molecules do dipole-dipole interactions occur in?
What causes ocean acidification?
The excess absorption of carbon dioxide from the atmosphere into the ocean.
What pH levels are considered basic?
pH of 8 to 14
Does BLA gain or lose?
Lose
What is a limiting reactant?
The reactant that is completely used up first in a chemical reaction.
What is a hydrogen bond?
A bond that occurs when a hydrogen atom is bonded to a highly electronegative atom
CH4 (g) + H2S (g) ⇆ CS2 (g) + 4H2 (g)
Disturbance: ↑ [CS2]
Which way would the equilibrium shift?
Left
If something has a pH level of 2, what is it considered?
Acidic
What is the BLB and BLA for the following problem: H₂O + HI ⇄ H₃O⁺ + I⁻
BLB:H2O
BLA:HI
Is this a double displacement reaction: CH4 + 2O2 -> CO2 + 2H2O
No. It is a combustion reaction.
Are London dispersion forces temporary?
Yes
CH4 (g) + H2S (g) ⇆ CS2 (g) + 4H2 (g)
Disturbance: ↑ CH4
Equilibrium shift: R
Would the following increase or decrease:
[CH4 ] [H2S] [CS2] [H2]
[CH4 ]= decrease
[H2S]= decrease
[CS2] = increase
[H2]= increase
If something has a pH level of 7, what is it considered?
Neutral
What is the CA and CB for the following problem: H₂O + HI ⇄ H₃O⁺ + I⁻
CA: H2O
CB: I-
Is this a double displacement reaction: AgNO3 + NaCl -> AgCl + NaNO3
Yes.
What is the strongest intermolecular force?
Hydrogen bonding
