Le Chatelier’s Principle, pH, & Ocean Acidification
What does ocean water do to carbon in the air?
It absorbs carbon from the air into the water

Calculate #mol H2O produced with 1.068 mol CO2
BCE: C3H8 (g) + 5O2 (g) ---> 3CO2 (g) + 4H2O (g)
1.41 mol H2O
clasify what reactoin type this is:
BiPo-->Bi + Po
Decomposition
What are Intermolecular Forces?
the chemical bonds that hold atoms together in a molecule
Why is the ocean becoming acidic a negative thing for the environment?
Acidic ocean water will kill many fish species and dissolve things like corral reefs.
What are the characteristics of an acid?
Acids have a low pH, and they donate protons in a chemical reaction.
Calculate the #g O2 needed if 8.35 x 1026 molecules CO2 form.
BCE: C3H8 (g) + 5O2 (g) ---> 3CO2 (g) + 4H2O (g)
7.40 x 104 g O2 (After rounded to proper amount of SF)
Clasify what kind of reaction this is:
SB+AlCo--> SAl+BCo
Double Displacement
What is Hydrogen Bonding?
A special type of dipole dipole interaction force that involves hydrogens.
If ↑[O2], what will happen to the rest of the reaction?
2H2O (g) ⇌ 2H2 (g) + O2 (g)
[H2O]↑ [H2]↓ [O2]↓
What are the key characteristics of a base?
Bases have a high pH level, and they accept protons in a chemical reaction, neutralizing acids.
If you have 98.6g H2S, how many moles of S8 are needed?
BCE: 8H2 (g) + S8 (g) ---> 8H2S (g)
23.15 mol S8
determine products of this single Displacement reaction
Ba+Al2(SO4)3 --->
Ba(SO4)3 + Al2
What is the name of this Chemical Formula
Sr2(CO3)2
Strontium carbonate
What would happen if the pressure increased?
2H2O (g) ⇌ 2H2 (g) + O2 (g) △H=485 kJ
[H2O]↑ [H2]↓ [O2]↓
What is Chemical Equilibrium?
A reversible chemical reaction where forward reactions and reverse reaction happen at the same rate
Calculate the molarity of solution prepared by disolving 79.386g InPO4 in enough water to make 40.85 liters of solution.
0.009261 M InPO4
Balance this equation:
H2 + O2 --> H2O

What is the chemical formula for Manganese(II) bromide?
MnBr2
If tempature goes up, what will happen to the rest of the equation?
2H2O (g) ⇌ 2H2 (g) + O2 (g) △H=485 kJ
[H2O]↓ [H2]↑ [O2]↑
Calculate the [OH-1] in an aqueous solution at 25oC with 1.0 x 10-4 M H+1. Determine the solution type.
1.0 x 10-10 M. This solution is acidic.
You have: 56 marshmallows, 120 graham crackers, and 232 pieces of chocolate. The recipe you are using requires: 2 marshmallows, 4 graham crackers, and 8 pieces of chocolate. What is the Limiting Reactant?
The limiting reactant is marshmallows because they only allow you to make 28 s'mores.
