Chatelier's Principle
How does the imbalance of a chemical equation change the arrows in a Chatelier Principle?
It has to change the directions of the arrows to balance itself from the concentration of a given molecule.
Relay a molecule on the pH scale with a given pH of 7. Acid neutral or base?
It would be a neutral solution
What is the conjugate base pair for BLA?
CB
What is a double displacement reaction?
A reaction that exchanges bonds between two compounds
What are the four types of intermolecular forces?
London dispersion force, Dipole-dipole force, ion-dipole force, and the hydrogen bonding force
What do the arrows represent in a Chatelier Principle equation?
They represent the concentration of a given molecule and the switching of molecules
Relay a molecule on the pH scale with a pH of 4.5.
Acid neutral or base?
Weak or strong?
It would have to be a weak acid solution
Find the limiting reactants and excess reactants:
There is 3 mol Zn and 4 mol HCL. On a balanced equation, the coefficients are 1Zn and 2HCL
1Zn + 2HCl
3 mol Zn/1 = 3, 4 mol HCL/2 = 2
HCL is limiting reactant
Zn is excess reactant
What chemical reaction is C + O2 >< CO2?
The chemical reaction is classified as a synthesis reaction
What is hydrogen bonding?
The forces between nearby molecules when there is an NH or OH polar bond
How does ocean acidification change marine life?
Ocean acidification increases the CO2 content in ocean water. This erodes plant life, fish, and the very habitats that sealife live in.
How is acidification and climate change related?
Both concur from the increased CO2 level in the present atmosphere. Acidification is by proxy a byproduct of climate change
If you were to convert grams into mol, how many positions would you pass?
You would go through two streets and moletown, making three positions total
Find the molar mass of H2O
1.00784 x 2 = 2.10568 + 16.00 = 18.01568g/mol
What is the chemical formula for salt?
NaCl
What is the antacid neutralization reaction?
The reaction of antacids with hydrochloride acid in one's stomach, reducing the overall concentration of acid in the stomach.
What is pOH?
It's the calculation of potential hydroide ions in a given solution. Higher concentrations of hydroxide ions make more basic solutions
What is the molarity of 0.25 mol of NaCl in 300mL of solution?
Molarity = 0.25mol/0.3L = 0.83 Molarity
Find the products in this single displacement reaction.
Mg + Fe,O
Mg+Fe2O >< Fe + MgO
How would you name Ir(moO4)
Iridium Molylobdate
What do antacid neutralization reactions change in the human stomach?
The concetration of acid present, leading to formed water, salt, and reducing acid-based afflictions like heart burn and acid reflex.
Solve the acid and base chemical equation:
H, H3, O2 + H2O(left arrow, right arrow) H3, O + C2, H3, O3
( find concentrations of total hydroxide ions on both side of arrows, connect the most associated molecules, and find the final set of reactions )
H3, O2 BLA to C2,H3,O2 CB, ACBP
H2O BLB to H3O Ca, BCAP
How many moles of O2 will be produced from 6.2 moles of water?
Balanced equation is 2 H2O >< 2H2 + 1O2
6.2 mol H2O/ 1 x 1 mol O2/ 2 mol H2O = 3.1 mol O2
Find the products and balance the equation of this double displacement reaction.
CaCl2 + Na3, PO4
CaCl2 + Na3, PO4 >< NaCl + Ca3(PO4)2
What is the chemical for sucrose?
