Moles
The number of items in a mole of anything
What is 6 x 1023?
The gram is the basic unit of mass in this system
What is the metric system?
This subatomic particle has a weight of 1 amu
What is the proton?
A chemist with an unknown substance could use this kind of reaction to discover what elements are in the substance
What is "a decomposition reaction?"
The molecular formula tells you this
In a chemical equation, these tell you the number of moles of a substance that is participating in the reaction
What are the (stoichiometric) coefficients?
If the scale you are using weights to the nearest gram, this is how many decimal places you should have
What is one? (because you always estimate a measurement to one more decimal place)
This subatomic particle weighs just slightly more than 1 amu
What is the neutron?
If a chemist decomposes 100 grams of a compound into three separate elements, the sum of the weight of those products will equal this
What is 100 grams?
This tells you that a molecular formula is not an empirical formula
What is if all the subscripts have a common factor?
That is "Mole Day"
What is October 23rd?
This number from the periodic table is the key to changing grams of an element into moles of that element
What is the atomic weight?
This subatomic particle doesn't contribute to the atomic weight at all
What is the electron?
The reactant that runs out first
What is the "limiting" reactant
This is an example of a substance whose empirical and molecular formulas are the same
What is water, carbon dioxide, hydrochloric acid, table salt, any of the homonuclear diatomics, etc.? (Only one example is needed)
The other name for the number of items in a mole
What is "Avogadro's number?"
This food is a homophone to "grams"
What are graham crackers?
The atomic weight is in amus, but we can also attach this unit to it
What is "grams/mole?"
In this case, and only this case, you can use the stoichiometric coefficients to mean liters
What is when you are working with gases?
The piece of data you need to go from an empirical formula to a molecular formula
What is the grams/mole, aka "the molar mass," aka "the gram molecular weight?" (only one correct answer is needed)
What is 72 grams?
This is the English unit that corresponds to grams
What are "slugs?" (Ewwww!)
The existence of these is the reason that atomic weights are not integers
What are isotopes?
The law that makes a balanced equation the essential starting point for stoichiometry
What is "The Law of Mass Conservation?"
Carbon tetrachloride
What is CCl4?
