Final Exam Study Cards

Question 1

The Kinetic Molecular Theory regards gas atoms as..?

Answer 1

1. Constantly in Motion
2. Always moving in a straight line
3. If they collide, the bounce off one another
4. Very spaced out.

Question 2

What is Pressure?

Answer 2

The sum of all collision of gas particles against their container walls. Force/Area. Think PSI, pounds per square inch.

Question 3

Basic Units of Pressure?

Answer 3

Atmosphere, Hg mm, PSI, Pascal

Question 4

1 atm to HgMM?

Answer 4

760 HgMM to 1 ATM

Question 5

What is the combined gas law?

Answer 5

P1V1/T1 = P2V2/T2. It is Boyles’ Charles and Gay-Lussac’s laws combined.

Question 6

What is the Ideal Gas Law?

Answer 6

PV=nRT. N is the moles of the gas, R is the .0821 L* atm/Mol* k. So, Pressure time volume= moles of gas times R times temp

Question 7

STP Conditions are..?

Answer 7

1 atm and O C/273 K

Question 8

How much volume does 1 mole of gas take up at STP?

Answer 8

22.4L

Question 9

What is a Solvent and a Solute?

Answer 9

A Solute is the dissolved substance, the solvent is the dissolving substance

Question 10

What does Undersaturated, Saturated and Super Saturated mean?

Answer 10

Under saturated means a solvent has less than the maximum amount of solute dissolved in it, saturated means it’s at maximum, super satured means above max.Think about Koolaid, under is the sorta-clear stuff, saturated is perfectly mixed, super is when there’s lil clumps of koolaid powder at the bottom.

Question 11

An electrolyte compound is..?

Answer 11

A solution with ions dissolved in it.

Question 12

What is H+?

Answer 12

A proton. H is 1 electron, 1 proton, no neutrons, so H w/o it’s electron is a Proton.

Question 13

Soluabillity and Temperature share a _____ relationship in Solids

Answer 13

Direct. As temperature goes up, so does soluabillity in solids

Question 14

Soluabillity and Temperature share a _____ relationship in gases

Answer 14

Reverse. This is Henry’s law. Think about how Cold sodas are better carbonated.

Question 15

Mass Percent in Solutions is?

Answer 15

Mass g solute/mass g solution

Question 16

Molarity is..?

Answer 16

Moles of Solute/L of . Big M

Question 17

Molality is?

Answer 17

Moles of Solute/KG of Solvent. little m.

Question 18

What is the relationship between Molarity and Volume?

Answer 18

Inverse. As Molarity goes up, Volume must go down. M1V1=M2V2

Question 19

Stoich w/ Volume?

Answer 19

Start with the solution you know both volume and molarity and stoich it out.`

Question 20

KMI?`

Answer 20

K= constant for freezin/boiliing, m is the molality of the substance, i is the amount of seperate atoms/molecules it makes

Question 21

What Are Acids?

Answer 21

Substances that produce H+ ions in aqueous solutions.

Typically sour, can dissolve metals

Question 22

What Are Bases?

Answer 22

Substances that produce OH- ions in aqueous solutions. Typically bitter, slippery in solid form

Question 23

What is the Arrhenious definitions of Acids and Bases?

Answer 23

The h+ and oh- definitions

Question 24

What is the Bronsted-Lowry definition of Acids and Bases?

Answer 24

Acids are Proton donors, Bases are proton acceptors

Question 25

What is the conjugate rule?

Answer 25

Acid turns into conjugate base, vicey versy.

Question 26

Naming Conventions for Acids/Bases?

Answer 26

Flowchart:

1. Doesnt Oxygen? Hydro-element-ic acid.
2. Does? Ion ends in ate, do ic. Ends in ite, do ous.

Question 27

What are the product of Arhenious Acid-Base reactions?

Answer 27

Water + Ionic salt

Question 28

What are the products of Bronsted Lowry Acid-Base Reactions?

Answer 28

H2O + Co2+ Ionic Salt. Think uh, combustion and CHO.

Question 29

The difference between Weak and Strong bases/acids?

Answer 29

Strong acids/bases completely break apart when they dissolve in solution, and weak acids/bases only partially break apart when dissolved.

Question 30

How does the PH Scale work?

Answer 30

1-6.99 is Acidic, 7 exactly is neutral, 7.01-14 is basic.
