Final Flashcards
What is a alkane?
Single bonded hydrocarbon. Ends with “Ane”
What is a alkene?
A single bonded hydrocarbon. Ends in “ene”
What is a alkalyne
A triple boned hydrocarbon. Ends in “yne”
What is matter?
1) anything with mass that occupies space
2) anything that requires a force to move/stop
What are the states of matter?
Solid, liquid, gas, plasma
To observe means?
Use your vision
What is quantitative observations?
Very general observations using words to describe
What is an interpretation?
The way something is based. Forming conclusions, predictions based on the information given through observations.
What is energy?
That which is not matter, but can cause change
Energy is conserved (but can be transferred between forms)
What is potential energy?
Stored energy
What is standard measurement?
An absolute that measurements are compared to; m, kg, s
What is a quantity measurement?
A property that can be described by a number and a unit that describes that standard.
What is a Derived unit of measurement?
A measurement made up of 2 or more standards; m/s
To find unitary rate?
Put what you have as an exponent to 10 and divid it over what you want as an exponent over 10
What is a solid?
Generally rigid, has its own shape/volume
What is a liquid?
Takes the shape of its container
What is a gas?
Completely fill its container
Will change drastically to temp and pressure
What is a melting point?
The temperature in which a substance changes from solid to gas
What is a boiling point?
The temperature in which a substance changes from liquid to gas
What is a freezing point?
The temperature in which a substance changes from liquid to solid
What is a condensation point?
The temperature in which a substance changes from gas to liquid
What is a sublimation point?
The temperature in which a substance changes form solid to gas
What is a chemical change?
When new substances with different property’s are formed
What is a physical change?
When no new substances are formed(phase changed) and/or properties are unchanged
What is a macroscopic observation?
Large enough to see with the naked eye
What is a microscopic observation?
Too small to see with the naked eye
What is a pure substance?
Matter with one set of properties. Either element or compounds
What is an ion?
+/- charged particles
Ionis compounds melt to form conducting solutions
Non metal melt to for non conduction solutions
What is a mixture?
Matter that can be separated by simple physical means.
What are Suspensions?
They’re are undissolved particles large enough to see which can be filtered or will settle themselves
What are colloids?
Undissolved particles that are to small to see, but they do not settle and connotation be filtered out. (Milk)
What are Solutions?
The are no undissolved particles. It is uniform throughout. All particles are completely dissolved
Aristotle
Matter is composed of earth fire and air
Democritus
Matter is composed of very small indivisible shaped particles the “atoma”
Dalton
Matter is composed of indivisible, indestructible very small particles that were the same for each element “solid spere” model
Thomson
Electron disk were electrons were imbedded in a mass +
“Plum pudding” model
Rutherford
Positive nucleus with electrons orbiting empty space
“Solar system” model
Bohr
Refines the solar system model –> orbits and attempts to predict combing capacity
de Broglie
Positive nucleus several nuclear particle electron “clouds”
What is the electron configuration?
1s 2s 3s 3p 4s 4p 5s 4d 5p
