The density of water is
1 g/ml
10 g/ml
1/2 ml/g
1 ml/g
Ethanol has a density of 0.83 g/ml. If an object with a density of .75 g/ml is placed in the ethanol, it will
float
sink
remain suspended
react violently
A bar of copper measuring 25cm x 12cmx 5 cm is found to have a density of 8.96 grams per cubic centimeter. The bar is then sliced in to three equal pieces. The density of each new piece of copper is
now only 1/3 the original density.
now 3 times the original density.
unknown and would have to be recalculated.
still the same as the original density.
Mrs. Rejmer was purchasing glass to make a new pendant with a very irregular shape. To determine the volume of glass needed, she should
place it on a scale to get the weight of the new glass.
use a ruler to measure it's circumference then multiply by pi.
use water displacement to see how much water is displaced.
Coach Strong and Ms. Frix were practicing their archery. Each time Ms. Frix shot she came very close to the center of the bullseye, but missed it by a tiny bit. Ms. Frix was
accurate, because she was very close to the center of the bullseye.
precise, because she hit the same spot every time.
Neither accurate nor precise because she never hit the bullseye.
Coach Strong and Ms. Frix were practicing their archery. Each time coach Strong shot, he hit exactly in the same spot but it was in the top corner of the whole target. Coach Strong was
accurate, because he hit the same spot every time.
precise, because he hit the same spot every time.
Neither accurate nor precise because he never hit the bullseye.
A poisonous gas is reacted with an explosive solid. The resulting compound is most likely
still going to be very dangerous, because each element making it is dangerous.
going to be harmless, because two harmful substances always form something not harmful.
different than either of the elements that form it, but could be harmless or dangerous.
Refer to a PTOE as you look at this model. It is a model of
oxygen
neon
fluorine

Look at this diagram. From it's valence electrons you can tell that
it is not reactive.
it is highly reactive.
it is slightly reactive.

What are TWO things you can know by looking at the GROUP that an element is located in? (Choose TWO)
How many shells / energy levels it has.
How many valence electrons it has.
How reactive it is.
How many neutrons it will have.
How much mass each proton has.
Periods on the periodic table inform us about
how many shells /energy levels an atom will have.
how reactive the element will be.
how many neutrons are in a normal isotope.
the element's total atomic mass.
The horizontal (that is side to side or left to right) rows on the PTOE are called
families
groups
periods
compounds
Vertical columns (that's up and down or top to bottom) on the PTOE are called
groups
periods
isotopes
ions
