Ocean Acidification
what is ocean acidification?
it is when the ph levels in the water increases
Calculate the Molar Mass (MM) of the Solute (MgSO4).
120.37 g/mol
What is Reversible Reaction (RR)
Chemical Reaction (Chem Rxn = CR) where Products can react to reform Reactants.
what four IMF's are there?
1. LDFs
2.hydrogen bonding
3.dipole-dipole
4.lon-dipole
1 mol = 6.022 x 1023 atoms, molecules, particles (amp)
= 602,200,000,000,000,000,000,000 amp
What is ocean acidification caused by?
it is caused by pollution, and harmful chemicals put into the water.
Calculate #mol F2 produced if 6.98 g BF3 are needed.
BCE: 2B (s) + 3F2 (g) —> 2BF3 (s)
0.189
67.8gmol
labeling these parts on a chemical equation BLA, BLB, CA, CB, ACBP, and BCAP
H2O (l) + HF (aq) ⇌ F-1 (aq) + H3O+1 (aq)
answer is in work book
Why does water boil at a higher temp compared to hydrogen sulfide
they have stronger hydrogen bonds
F2 (g) + KI (aq) —> ?
2KF(aq)+I2(s)
what happens when you increase concentration in the problem CH4(g)+H2S(g)>< CS2(g) + 4H2(g)
The CH4 goes down and CS2 goes up
Calculate the #g O2 needed if 8.35 x 1026 molecules (molc) CO2 form.
BCE: C3H8(g) + 5O2(g) —> 3CO2(g) + 4H2O(g)
7.40x104 GO2
What is a strong acid and a weak acid
A strong acid has a lot of acidic propertites while a weak acid has very little acidic propertites.
What is the chemical name for Fe2(SO4)3
Iron(III) Sulfate
what is single displacement
Single displacement is where one element moves to the other side the the equation.
what happens when you increase pressure in the problem CH4(g)+H2S(g)>< CS2(g) + 4H2(g)
if you increase pressure CH4 and H2S pressure gives up while CS2 and H2 pressure goes down
Calculate Mole Ratio
2C4H10(g) + 13O2 (g) > 8CO2 (g) + 10H2O(g)
Mole ratio= 21.5/ mol O2
What is a strong base and a weak base
A strong base has a very strong structure while weak bases fall apart easily
How do you write the chemical formula for magnesium chloride?
MgCl2
what is double displacement.
double displacement is were two elements switch to the other side of the equation.
what happens when you increase temp in the problem CH4(g)+H2S(g)>< CS2(g) + 4H2(g)
If you increase temp CH4 and H2S goes up while CS2 and H2 go down
