🗑
Physical Chemistry   show
🗑
Analytical Chemistry   show
🗑
Inorganic Chemistry   show
🗑
show The study of carbon containing molecules and compounds; ( 1. Characteristics and reactivity of carbon compounds; 2. More complex than inorganic Chemistry; 3. Sophisticated testing techniques/instruments)  
🗑
show Study of living organisms, the chemistry that supports human life  
🗑
show anything that occupies space and mass  
🗑
Mass   show
🗑
Volume   show
🗑
Density   show
🗑
show a measure of teh gravitational attraction for mass. ( can vary according to location)  
🗑
show one of the millions of different types of matter found in teh world; Any substance can be classified as either an element or a compound  
🗑
show One of the 108 basic buliding blocks of all matter ( atom); 90 are naturally occuring on earth; 18 are man made in the laboratory  
🗑
show form of matter in which 2 or more elements are held together in a fixed ratio by a chemical bond  
🗑
show The ration of the mass of a solution to the mass of an equal volume of water at a specific temperature. (unitless)  
🗑
Solution   show
🗑
True Solution   show
🗑
Solute   show
🗑
show the liquid in a solid/liquid mix or the liquid in a greater quantity or lesser concentration in a liquid/liquid mix. (dissolving medium)  
🗑
Law of Conservation of Energy   show
🗑
Chemical Formula   show
🗑
Classification of Matter   show
🗑
show 1. Solid, 2..Liquid, 3. Gas  
🗑
2 Types of Composition   show
🗑
Homogeneous   show
🗑
show composition of matter is not uniform, equal or constant throughout the sample, matte exists in 2 distinct physical states  
🗑
Solid   show
🗑
Liquid (1)   show
🗑
show attractive forces in a liquid that are strong enoug to maintain a liquid sample in a fixed shape; (Cohesive force- IF b/w like molecules; surface tension), (Adhesive Force- the IF b/w unlike molecules; water wets glass)  
🗑
show Indefinite shape; Exert high vapor pressure; Diffused- very little attraction of atoms; Highly compressible; Indefinite volume (expand evenly); Force exerted called pressure or force per unit area (atm, PSI, mmHg=TORR)  
🗑
Factors which affect the states of matter (1)   show
🗑
Melting   show
🗑
show change from liquid to solid, temp at which is the "freezing point"  
🗑
Vaporization   show
🗑
show vaporization occuring at normal room temp  
🗑
show varies with a change in pressure of the liquid  
🗑
show matter that is uniform, consistent and of equal ratio throughout; Can be divided into different forms of matter: ( 1. Elements, 2. Compounds, 3. Solutions)  
🗑
Solutions are classified by   show
🗑
Unsaturated   show
🗑
show As much solute as solvent is capable of dissolving  
🗑
show More solute than is capable of dissolving at normal conditions  
🗑
show Mixture containing two or more phases or portions that precipitate (seperate); By convention mixtures are considered heterogeneous matter.
