What does inversely related mean?
When the decrease in one variable causes a reduction in the other variables
I think my weird cousin might be inversely related.
When the increase in one variable causes a reduction in the other variables
Is that what happens when someone is "1st cousins 17 times removed"?
2
What is Matter?
Anything that has mass and is in space
I'm doing great! Thanks for asking!
Anything that has mass and takes up space.
3
What is the nucleus?
The control center of the cell, contains DNA.
The center of the atom that contains neutrons and protons
Lara, that's not chemistry.
No! Not biology again.
4
What is a quantitative measurement?
The most exact measurement.
When measurements don't have to be exact.
An estimate.
5
What is a neutron?
One of three particles that make up an atom, and is electrically neutral.
Even more confused.
One of 3 particles that make up an atom, and is positively charged.
One of three particles that make up an atom, and is negatively charged.
6
What is Hertz (Hz)?
The unit for weight
The unit for frequency
The unit for distance
Chemistry?
7
What is precision?
An indication of how close a measurement is to the true value
An indication of the scale on the measuring device that was used
An inclination of how close a measurement is to the true value
8
What is a P orbital?
A spherical orbital with the nucleus in the center.
A dumbbell shaped orbital with a nucleus in the center.
I didn't know there was more than one shape of an orbital.
Only a smarty pants scientist can answer that.
9
What is the law of mass conversion?
Lara, I hate chemistry as much as you hate math.
Matter cannot be created or destroyed; it can only change forms.
Matter cannot change forms; it can only be created or destroyed.
10
What is accuracy?
An indication of how close a measurement is to the true value
Why are you asking me stuff from Module 1! You know I have slept since then
An indication of the scale on the measuring device that was used
11
What is Chemistry?
The form of science where you get to blow stuff up.
The study of matter.
The study of the Periodic Table.
12
What is an electron?
One of three particles that make up an atom, and is negatively charged.
I've been confused from the start.
One of three particles that make up an atom, and is electrically neutral.
One of 3 particles that make up an atom, and is positively charged.
13
What is a qualitative measurement?
Observations that are not counted or measured, such as color, texture
When measurements don't have to be exact.
The most exact measurement.
I think you mean quantitative.
14
What is a pure substance?
Water?
A substance that contains a noble gas
A substance that contains only one element.
15
What is an isotope?
I forgot about all this after Challenge B.
Atoms with the same number of protons, but different numbers of electrons.
Atoms with the same number of protons, but different numbers of neutrons
Atoms with the same number of neutrons, but different numbers of protons
16
If you do not include this in your answer it is considered incorrect:
Units
Numbers
Words
Uhhhh... the correct answer
17
What is a compound?
A substance that contains only one element or compound
Substances that can be decomposed into elements by chemical means.
A substance that contains different compounds and/or elements
18
What is the Factor Label Method (FLM)?
given unit x conversion factor = wanted unit
given unit + conversion factor = wanted unit
given unit − conversion factor = wanted unit
given unit ÷ conversion factor = wanted unit
19
What is a proton?
One of 3 particles that make up an atom, and is positively charged.
Still confused.
One of three particles that make up an atom, and is electrically neutral.
One of three particles that make up an atom, and is negatively charged.
20
What is an S orbital?
A dumbell shaped orbital with a nucleus in the center.
A specific shape that confines the position of an electron.
A spherical orbital with the nucleus in the center.
Lara, no matter what you think I am NOT a chemist.
