Chemistry

• Branch of Science

• Studiesthe propertis of matter and the changes it undergoes

Inorganic Chemistry

• Elements of life, doesn’t deal with C & H

Organic Chemistry

• Used in Body, deals with C & H

Antoine Van Lavoisier

• FATHER OF CHEMISTRY

• French chemist

Law of Conservation of Mass

What did Antoine Van Lavoisier propose?

Elements of Chemistry

What did Antoine Van Lavoisier write in 1789?

Mass

• Measured in Weight, kg, g , mg,  etc.

Space

• Measured in mL, L.

Matter

• Anything that occupies space and that has mass

Solid

1. Definite/ rigid shape

Liquid

1. Occupy container

Gas

1. No definite shape, and volume, it moves randomly (High entropy)

Plasma

1. most abundant state of matter

Entropy

• Degree of disorderliness

• High= magulo, Low= eg.solid

Substances

• A matter that has a definite composition

Mixture

• Combination of 2 or more substances

Homogenous

• Uniform solution (eg. Juice & water)

Heterogenous

• NOT uniform solution ( eg. Water and Oil)

Pure Substances

• Simplest form of matter

• Only has ONE kind of particle
  (eg. Elements)

Compound

• Simplest form of matter

• Only has ONE kind of particle
  (eg. Elements)

Compound

• Two or more particles/ particles

(eg. NaCl)

Melting

Solid to Liquid

Evaporation

1. liquid to gas

Condensation

1. gas to liquid

Freezing

1. liquid to solid

Deposition

1.  gas to solid

Sublimation

1. Solid to gas

Endothermic

• Absorbs heat 

• Specific latent heat can also be denoted as Δ H (enthalpy of vaporization or fusion)

Exothermic

• Releases heat 

Plasma

• Ionized gas

Recombination

plasma to gas

Ionization

Gas to Plasma

Filtration

1.  method of separating inorganic/ insoluble solid through a filter paper.

Magnetic Separation

separating components by a magnet.

Decantation

1. separating mixtures based on the difference of the specific gravity & density.

Distillation

separating mixtures in a series of evaporation and condensation.

Sieving

1. separating mixtures with a different particle size using a sieve or a mesh.

Intensive

Independent properties

• Density

• Specific gravity

• Boiling point (eg. Water= 100 degrees Celsius)

• Melting point (eg. Water= 0 degrees Celsius)

Extensive

dependent

• Mass

• Volume

• Length

Physical change

• a modification to a substance that alters its shape, size, or state of matter, but leaves its chemical identity completely intact

• Eg. Ice to water, glass breaking, etc.

Chemical change

• occurs when a substance's molecular composition is altered, resulting in entirely new substances with different properties

• Eg. Wood to ash, rotting fruit, etc.

Nuclear Change

Fusion and Fission

Fusion

 combination of nuclei

Fission

Splits up into 2

Law of Mass Action

• rate of reaction is proportional to the product of the concentrate of the reactants to the power if its coefficient in a Balanced Equation
