Chemistry 115

  • Chemistry - study of matter and its changes
  • Matter - something that occupies space
  1. Pure substances: well - defined physical and chemical properties
  2. Mixtures

Pure Substances:

Chemical Properties

Boiling pointIf you want to learn more check out osrr ecu

Melting point

Solubility

Density

How to reacts with other species e.g. sodium, oxygen, acid

  • 2 types pure substance:
  1. Elements - can’t be broken down any simpler e.g. sodium, iron, chlorine
  2. Compounds - made of 2 or more elements (can be broken down into its constituent elements)

Mixtures:

  • Combo of 2 more pure substances
  • Do not have a fixed composition

Mixture

DistillationDon't forget about the age old question of Chapter 1 Contou I be Why Pseudoscience?

Liquefaction

coalescence

  • 2 types of mixtures:
  1. Homogeneous - same composition throughout  e.g. bronze
  2. Heterogeneous - composition not same throughout

Units:If you want to learn more check out What is a painted backdrop of 3-D figures?

Measure of physical qualities (length, mass, time, etc) have:

  • A number and a unit
  • Many units for same physical property

E.g.: mass, ounce, pound, stone, hundredweight (U.S. and U.K.), ton (U.S and U.K.), metric tonne

1 pound (lb) = 16 ounces (oz)

1 stone = 14 lb

1 U.S hundredweight (cwt) = 100 lb

1 U.K. hundredweight (cwt) = 8 stone = 112 lb

1 U.S. ton = 20 cwt U.S. = 2000 lb

1 U.K. ton = 20 cwt U.K. = 2240 lb

1 metric tonne = 1000 kg = 2200 lb

Scientific / Exponential Notation:

Any number can be written in this form

X  x 10

E.g. 6000000m = 6x106m

*certain exponents represented by a prefix:

  • Prefix replaces x109

103 - kilo (K)                109 - giga (G)

106 - mega (M)        1012 - tera (T)

10-1 - deci (d)                10-6 - micro (N)

10-2 - centi (c)         10-9 - nano (n)

10-3 - mili (m)                10-12 - pico (p)

E.g.: 6x106m = 6Mn

Exponent Rules

109 x 10b = 109+b

(109)b = 109b

= 109-b

Unit conversions (dimensional analysis):

  • Conversion - factors relate 2 units

E.g. 1 yard = 3 feet,        12 in = 1 foot

*multiply by appropriate conversion so units cancel

example : convert 6ft. into yards

        6ft x == 2yd

Measurement uncertainty:

  • There is ALWAYS error associated with measurement, limited by precision of instrument

Graduation - level of precision

Rule: measure to most precise graduation and estimate next digit

Recognizing significant figures:

  1. All non - zero digits are significant e.g. 6.414 - 5 S.F.
  2. Trapped zeros are significant e.g. 6.02 - 3 S.F.
  3. Trailing zeros (w/decimal place present) are significant
  4. Lead zeros are not significant
  5. Training zeros (w/ no decimal place present) are ambiguous

E.g. 6000 - ambiguous

To remove ambiguity: write in scientific notation

  • 6.000 x 103 - 4 S.F.

Calculations involving Significant Figures:

  1. Multiplication / Division - answer has same number of significant figures as number in calculation that had least
