Stoichiometry
More commonly phrased as "What goes in must come out", this physical principle fully stated tells us that we cannot create something from nothing, nor can we destroy anything completely.

This constant, now called Avogadro's number, tells us the amount of particles in a given amount of any substance.
What is 6.022x1023?
This chemist's gas law tells us that, assuming volume and amount of gas is constant, that the pressure of a gas is directly proportional to its temperature.
Who is Gay-Lussac?
This term is used to describe a chemical reaction in which two solutions are mixed and a solid is produced.
What is a precipitation reaction?
This mnemonic helps you recall that most strontium, barium, and calcium salts are insoluble.
What is Castro Bear?
If, according to the below reaction, 28g of iron reacts with 22g of sulfur to form 44g of iron sulfide, this mass of sulfur remains unreacted.
Fe + S -> FeS
What is 6g?
If I have 2.80x1024 molecules of ammonia, then I have this mass of ammonia.
What is 79.2g?
Boyle's Law tells us that these two variables of a gas are inversely proportional to each other.
What are pressure and volume?
This group of elements will always form soluble compounds.
What are the group 1 metals?
This element is the strongest reductant on the periodic table, even though it is not the least electronegative element.
What is lithium?
The entire universe is the only possible example of this type of system, allowing no exchange of energy or matter with its surrounding environment
What is an isolated system?
This specific isotope is the foundation upon which the mole is defined, with 1 mole being exactly 12 grams of it.
What is carbon-12?
If a balloon full of gas had a volume of 0.080L at 25.0oC, then this is the temperature of the gas when it is heated and expands to 0.100L, in oC.
What is 93.3oC?
This metal will, at first, react slowly when placed into an acid, but once the oxide layer on its surface has been degraded, will react very rapidly with the acid.
What is aluminium?
If someone drank 85mL of a drink that was contaminated by thiocyanate ions (SCN-) such that their concentration was 12.13mmol/L, they would have consumed this many milligrams of thiocyanate ions.
What is 60mg?
Solid ammonium nitrate can explosively decompose into a mixture of nitrogen gas, oxygen gas, and water vapour, according to this fully balanced chemical equation.
What is 2NH4NO3 (s) -> 2N2 (g) + O2 (g) + 4H2O (g)
If the acceptable level of lead in Australian drinking water is 0.01ppm, then this is the concentration of lead ions in solution that is deemed to be the threshold of safety, in molarity.
What is 4.83x10-8M?
When under this specific set of conditions, 1 mole of an ideal gas will occupy 22.71L.
What is standard temperature and pressure (STP)?
This is the name for graphs that showcase the distribution of energy amongst a collection of particles.
What is a Maxwell Boltzmann Distribution/Curve?
This chemist is the one we have to thank for first developing the concept of oxidation and reduction equations, who originally thought that oxidation was the gain of oxygen and reduction was the loss of oxygen.
Who is Antoine Lavoisier?
When 12.3g of glucose undergoes decomposition by yeast, this amount of volume of ethanol, which has a density of 0.789g/mL is created.
What is 7.97mL?
If a theoretical polyatomic ion called the 'smartate' has a charge of -3, and the molar mass of strontium smartate is 327.34g/mol, then this is the molar mass of the smartate ion.
What is 32.24g/mol?
This temperature, with a specific name, is the temperature at which the movement of particles ceases entirely, and is the basis upon which the Kelvin scale of temperature was developed.
What is absolute zero?
In a galvanic cell between manganese and silver, this element will be the oxidant, AND results in this theoretical potential.
What is silver, and 1.98V?
No question! Just a challenge:
Take turns naming elements on the periodic table, gain 100 points per element, and an extra 100 points per extra piece of info about the element (e.g. symbol, mass, number)! Whoever is currently in last place will go first.
I hope this went well because I threw this in since I had no clue what else to put lol
