Types of Matter
These are the two main categories of matter
Pure Substances and Mixtures
A liquid's resistance to flow
Viscosity
Type of change when a new substance is formed
Chemical
The type of heterogenous mixture that forms layers over time and can be filtered. It has large and small particles.
Suspension
What do you call two or more types of atoms bonded together in a certain ratio
Compound
zero degrees celsius
melting point
A change that does not change the composition of the matter
Physical
The two types of pure substances
elements and compounds
A mixture that is not uniform throughout.
Heterogeneous
Allows the flow of heat or electricity
Conductivity
Dissolving a substance into a liquid is what kind of change?
Physical
A potato has a mass of 162 grams and a volume of 43 mL. What is its density?
3.8 g/mL
The substance that is dissolved by the solvent in a solution
Solute
Density formula
mass/volume
Solid chunks that separate from a liquid during a chemical change are called this
Precipitates
A solution can't be filtered, therefore we must use this method to separate the particles
What is distillation?
A mixture that has small, medium and large particles
Colloid
Can hold shape, can be hammered without shattering
malleability
These are the 3 main pieces of evidence that a chemical change has occurred
Color change, gas formation, precipitates
Name the 2 chemical properties we learned about
What is Flammability and Reactivity?
