Module 1 (Basic concept of inorganic chemistry) Flashcards
it occupies space and mass
matter
group of matter with the same properties
state of matter
arranged in regular repeating pattern
solid
reaction happen when it vibrates
solid
no definite shape and flows easily
liquid
its atom is more free compared to solid
liquid
its atom/ molecules fly in all direction at great speed
gas
attractive forces are insignificant as they are far apart
gas
contains protons and electrons
plasma
loses electron at very high temperature
plasma
result of the mixture of electron and nuclei
plasma
combination of 2 or more substances wherein their distinct properties are still the same
mixture
air, cement, milk, coffee, and softdrinks
mixture
have definite and constant composition and distinct properties
pure substances
ethanol, table salt, carbon dioxide, water and silver
pure substances
homogeneous and heterogeneous
mixture
composition of the mixture is the same through out the solution
homogeneous mixture
composition of the mixture is not uniform
heterogeneous
substance that cannot be broken down into smaller substance by chemical means
element
combination of 2 or more element
compound
can be observed or measured
physical properties
have chemical changed
chemical properties
boiling point, freezing point, color, shape, and odor
physical properties
boiling, freezing, acidity and flammability
chemical properties
something you can measure
extensive property

extensive property
does not result in new substance
physical change
result to a new substance
chemical change
freezing, boiling, and bending
physical change
rust in a nail and burning of paper
chemical change
measured quantity written in numbers
measurement
can bee seen directly or can be seen through naked eye
macroscopic property
