What is proper lab attire for any lab?
You should always wear a lab coat and goggles.
100
What is the definition of matter?
Matter is anything that has mass and volume.
100
What are the four main parts of an atom?
The three main parts are the nucleus, proton, neutron, and electron.
100
What does the Roman Numeral represent in Type II Ionic Compounds?
It shows you the charge of the cation.
200
What is the acronym for the metric conversions and what do the letter stand for?
K.H.D.B.D.C.M. Kilo, hecto, deca, base, deci, centi, and milli.
200
What are the four basic states of matter?
The four most common states are solids, liquids, gasses, and plasma.
200
What is the definition of "wavelength?"
Wavelength is the distance between corresponding points on adjacent waves.
200
What are the three main types of elements on the periodic table?
Metals, Non-Metals, and Metalloids.
200
What is the difference between Type I and Type II Ionic Compounds?
Type I comes from the +1, +2, and +3 labeled columns, while Type II comes from the D-block, F-block, and some P-block metals.
300
What are the basic units of measurement?
Volume, mass, length, density, and temperature.
300
What is the formula to measure matter?
Density=Mass/Volume
300
What is a "photon?"
A photon is a particle of electromagnetic radiation that has zero rest mass and carries a quantum of energy.
300
What is the difference between a period and a group on the periodic table?
A period is a horizontal row, while a group is a vertical row.
300
What is the difference between a cation and an anion?
A cation has a positive charge, while an anion has a negative charge.
400
How do you measure irregularly shaped objects?
You can measure them using the "Water-Displacement Method."
400
What is the difference between weight and mass?
Mass is the amount of space an object takes up, while weight is the measure of the pull of gravity on an object.
400
What happens when waves flow between two slits?
They cause an interference pattern and neutralize each other.
400
What are the four man types of families in the periodic table?
Alkali Metals, Alkaline Earth Metals, Halogens, and Noble Gasses.
400
What is the chemical formula for Carbon Tetrahydride?
CH4 (the "4" is a subscript digit)
500
How many significant figures are in 101.0 L + 34.66 L?
There are 4, and the answer is 135.7 L.
500
What are the three direct/inverse relationships?
Inverse: Speed of Light=(Wavelength)(Frequency) Inverse: Energy=(Constant)(Speed of Light)/Wavelength Direct: Energy=(Constant)(Frequency)
500
Why don't Noble Gasses form ions?
They don't need to form any because they are already stable.
