States of Matter
Are the molecules closer together in a liquid or a gas?
What's the relationship between pressure and volume?
Pressure goes up, volume goes down.
What’s the relationship between molarity and concentration?
The higher the molarity, the higher the concentration.
What is the collision theory?
Atoms, ions, and molecules must collide in order to react.
What’s the pH level difference between an acid VS base.
Acid’s pH is below 7, while base’s pH is above 7.
What is one part of the kinetic molecular theory?
Matter is made up of tiny particles that are constantly moving.
What's the formula to find heat energy.
𝑞=𝑚𝑐Δ𝑇.
What is a heterogeneous mixture VS a homogeneous mixture?
A heterogeneous mixture has components that are unevenly distributed meanwhile a homogeneous mixture has components that are evenly distributed.
What’s activation energy and how does it work with a catalyst?
Energy needed to begin a chemical reaction. A catalyst speeds up the reaction and lowers the activation energy.
What does an acid contain and base contain?
Acid has H+, and base contains OH-.
What is electronegativity?
How “selfish” an atom is.
What is 1 mol equal to?
6.022 x 10^23.
What's the dilution equation?
M1V1 = M2V2.
How can you spot an intermediate?
It appears as a product first then a reactant.
What are the products of a neutralization reaction between a strong acid and a strong base?
Salt and water.
Rank the Intermolecular forces from the strongest attraction to the least attraction
Hydrogen Bonding, Dipole-dipole, then London dispersion.
A piece of metal is cooled from 600K to 300K, what happens to the pressure?
Pressure decreases.
Moles in 10 mL of a 6M solution.
0.06 mol.
What is the result of the pace if the activation energy is increased?
The higher the activation energy, the slower the pace is.
If a solution has a pH of 8, what is its pOH?
6.
What’s the difference between cohesion and adhesion?
Cohesion is the attraction of molecules to other molecules of the same kind while adhesion is the attraction of molecules to other molecules of different kinds.
A balloon has a volume of 9L while the pressure is 4 atm. The pressure increases to 6 atm. What is the new volume of the balloon?
6L.
A solution has 20g of solute dissolved in 60g of solvent, what is the percentage by mass of the solute?
25%
What happens if all steps are added together?
A complex reaction is made.
What is the equation for solving pH?
pH = -log [H+].
