Chemistry

​is the study of matter

deals with the composition of matter and the changes that matter may undergo.

​Study of compounds that contain elements carbon and hydrogen.
Example: Petroleum, food, and all medicine

​​ORGANIC

​Made up of only one or no carbon element
Examples: Crystal structures, periodic elements

​​INORGANIC

It has qualitative analysis which is more on the physical properties and identify and quantitative analysis or amount of certain substance.

​​ANALYTICAL

​Relies on a lot of physics and math to study the changes in energy that happen to matter.

​​PHYSICAL

​BRANCHES OF CHEMISTRY

the study of the synthesis, characterization and properties of polymer molecules or macromolecules, which are large molecules composed of repeating chemical subunits known as monomers.

​​Polymer

​artificial execution of chemical reactions to obtain one or several products

Synthetic

​BRANCHES OF CHEMISTRY

MASS

THE AMOUNT OF MATTER CONTAINED IN THE OBJECT.

MASS DOES NOT CHANGE.

IT IS CONSERVED DURING CHEMICAL REACTION.

MASS OR REACTANTS IS EQUAL TO THE MASS OF THE PRODUCTS

​Weight

Is the gravitational pull on an object.
Changes based on energy

ENERGY IS THE ABILITY TO DO WORK
ENERGY IS ALWAYS CONSERVED

Pure Substances & Mixtures

Some text here about the topic of discussion

a. CAN BE HOMOGENOUS SOLUTION= SOLUTE +SOLVENT
b. CAN BE HETEROGENOUS

​MIXTURES

Can be divided into:
a. Element
b. Compound

PURE SUBSTANCE

MATTER can be classified into:

Pure Substance

Has a set composition 

Is either an element or compound

diverse or not the same

​heterogenous

uniform all through out the substance

homogenous

MATTER can be divided into:

Elements are made of a single type of atom while a compound is 2 or more types of atoms bonded together.

Mixtures

Made of 2 or more substances but not chemically bonded

Original substances can be separated by physical means

Can be heterogeneous or homogeneous

Homogeneous Mixture is uniform and evenly mixed!

Heterogeneous Mixture is NOT uniform and NOT evenly mixed!
