Define a polar covalent bond
Non-metals share an electron unevenly, resulting in partial charges based on differences in electronegativity.

What happens to the volume of a flexible container if the temperature of the gas in that container in creases and why.
V increases, temp increase makes the molecules more more, causes them to spread out and expand the container.

What is the mass, charge and location of a neutron?
1, neutral, nucleus

Draw the lewis structure, including any partial charges, and determine the 3d shape.
SbAtH2
trigonal pyramidal, Sb central with 1 lp, no partial charges, non-polar

If temperature is constant, what happens to the pressure in a container if the volume of the container increases, and why.
Increasing volume moves walls farther apart, means molecules hit walls less, Pressure goes down
Think pulling a syringe back

A carton of milk contains a mixture. A bowl with milk and Cheerios also contains a mixture. Which one is homogenous and which one is heterogenous, and explain why.
Milk = homogenous, water, proteins, fats, sugars, but all looks the same/cant see the different parts
Milk & cereal = heterogenous, can see different parts

Draw the lewis structure, including any partial charges, and determine the 3d shape.
CAtF3
tetrahedral, all single bonds, At partial plus, Fs partial negative, polar molecule
300
What happens to the temperature of a gas in a container if the pressure is increased
Temp goes up
Compressing causes more molecular movement/collisions between molecules

Write the two conversion factors you could use to convert units back and forth between liters and microliters
1uL = 10-6L, so
(1uL)/(10-6L)
or
(10-6L)/(1uL)

Which would you expect to have a larger atomic radius Zr or Te, and why?
Zr, same row but farther to the left, has same number of shells but fewer protons, electrons are less attracted to nucleus (lower electronegativity).

Convert 123 kilometers to meters using scientific notation and base 10 math.
123 km is 1.23 x 102 km
1km = 103 m
(1.23 x 102 km)/1 x (103 m)/1km = 1.23 x 105 m

Explain why dissolving salt in water in not considered a chemical change
No new compounds are formed, and none of the old compounds are chemically changed (no chemical bonds formed or broken)
The salt molecules are just spread out evenly in the water. Can be separated by evaporating the water (boiling point is a physical property)

Convert 123 kilometers to centimeters using scientific notation and base 10 math.
123 km is 1.23 x 102 km
1km = 103 m. 1cm = 10-3m
(1.23 x 102 km)/1 x (103 m)/1km x 1cm/(10-3m)
1.23 x108 cm
