What's Your Type? (and Balance!)
This general reaction format is represented by the equation A + B --> AB
Synthesis Reaction
At standard temperature and pressure (STP), 1 mole of any ideal gas is always equivalent to this volume in liters.
22.4 L
This term describes a process where heat enters the reaction and the substance gets colder.
Endothermic
To calculate the molarity (M) of a solution, you divide the moles of solute by this specific unit of measurement.
Liters
In this specific type of reaction, a single element displaces another element from a compound following the format A + BC --> B + AC
Single Replacement
Based on the balanced equation 2H2O --> 2H2 + O2, this is the exact number of moles of H2 created when 0.5 moles of H2O completely react.
0.5 moles
In the heat transfer formula q = mc(delta)T, the variable c represents this exact property of a chemical
Specific Heat Capacity
This is the final molarity of a 3.5 L solution that contains 1.75 moles of KMnO4.
0.5M
These are the two missing coefficients needed to balance the following expression: Cl2 + __NaBr -->__NaCl + Br2
2 and 2
Given that the periodic table mass of O2 is 32 g/mol, this is the number of moles contained in 128 g of O2 gas.
4 moles (128g/32g = 4 moles)

Endothermic
On a solubility curve graph for KNO3 in H2O , this word correctly labels the region below the curve line.
Unsaturated
This type of chemical reaction involves two compounds swapping ion partners, written as AB + CD --> CB + AD
Double Replacement
This is the total volume in liters occupied by a 5.76 mole sample of Neon (Ne) gas at STP
129.024 L (5.76 moles x 22.4 L/mol = 129.024L)
This is the total amount of heat energy absorbed when 120g of water undergoes a temperature change of 45 degrees C, given water's c is 4.18 J/g degrees C
22.572 J
Using the dilution formula M1V1 = M2V2 , this is the volume of 0.30 M NaCl stock solution required to create 0.20 L of a diluted 0.15 M NaCl solution.
0.10 L
When balancing the equation Na3P + __HCl --> __NaC + H3P this is the missing coefficient for both HCl and NaCl

This is the key reason it is vital for airbag scientists to precisely calculate gas conversions between mass, moles, and liters.
To ensure the airbag inflates with the exact volume of gas needed to safely protect a passenger without under-inflating or bursting?
If a 50g sample of a chemical absorbs 12,000J of heat and experiences a temperature change of 15 degrees C, this is its calculated specific heat capacity.
16 J/g degrees C
If a doctor asks for 50L of solution containing 0.5M Mg , this is the volume you must pull from a concentrated stock solution of 5M Mg.
