What is Chemistry?
Chemistry
The study of the structure and composition of matter, the physical changes it undergoes and the energy that is exchanged
Element, compound, solution
what is classifications of homogeneous substances
the amount of parts in a solution
what is 2
mixture that is not one phase
What is a heterogeneous substance
Water
homogenous compound
Law of Conservation of Matter
Matter can neither be created nor destroyed
matter composed of only one type of atom
what is an element
the component which whose phase is changed
what is a solute
made of dry particles of different types of elements/ compounds
what is a dry heterogenous mixture
copper penny
homogenous element
Homogeneous
Means that it is one phase throughout; completely uniform
substances composed of more than one atom chemically joined together
what is a compound
the component which remains the same
what is a solvent
a mixture whose particles are evenly distributed and bigger than the particles in the solution
What is a Calloid
baking soda
what is a homogenous compound
Heterogenous
means that matter is made up of more than one phase
uniform mix of two or more substances which are not chemically bonded
what is a solution
if they dissolve in each other completely and mix uniformly
what is miscible
A mixture who's particles are so large that they settle out unless constantly agitated
what is a suspension
Solid to a vapor
what is sublimation
chocolate chip cookie
heterogeneous
H20
what is a compound
when two metals are melted together
T/F: heterogeneous mixtures are always mixtures
what is true
