1

Limiting Reagent

Reactant that produces the LEAST product

 

1. Calculate the amount of product with REACTANT ONE.

 

2. Calculate the amount of product with REACTANT TWO.

 

SMALLEST AMOUNT OF PRODUCT? Limiting Reagent.

2

Thermochemistry ENDOTHERMIC REACTION

Positive delta H

 

ABSORBS energy

 

Melting (solid to liquid)

 

Vaporization (liquid to gas)

3

Thermochemistry

 

EXOTHERMIC REACTION

Negative delta H

 

RELEASES energy

 

Freezing (liquid to solid)

 

Condensation (gas to liquid)

4

Charles' Law

 

 

 

Assumptions:

Constant n (moles), Constant P (pressure)

 

 

 

 

8

Gases

 

Boyle's Law

Assumptions:

Constant n (moles), Constant T (temperature)

9

10

Dalton's Law (Partial Pressures)

11

Solutions (Saturated, Unsaturated, Supersaturated)

12

Solutions: Colligative Properties 

Properties of a solution that CHANGE when you increase solute

13

Solutions: Colligative Properties 

14

Solutions: Colligative Properties 

15

Acids/Bases

 

pH = ?

pH = -Log10[H+]

16

Acids/Bases

 

pOH = ?

 

pOH = -Log10[OH-]

17

If pH = 9, what is [H+]?

pH = 9

 

-Log10[H+] = 9

 

Log10[H+] = -9

 

10-9 = [H+]

18

pH + pOH = ?

14

19

Strong Acids and Bases

 

(Assume complete dissociation)
