The Mole
This is the molar mass of Xenon.
What is 131.29 g/mol?
This is considered the universal solvent because it is a polar molecule that will dissolve most substances.
What is water?
Acid or Base: This substance has a pH of 2 and tastes sour.
What is an acid?
This is the theory that science uses to explain the behavior of gases.
What is the kinetic molecular theory (KMT)?
This is a process in which you gain heat.
What is endothermic?
This is the molar mass of NaCl.
What is 58.44 g/mol?
This is the solute in koolaid.
What is koolaid powder or sugar?
Acid or Base: This substance has a pH of 10, tastes bitter, and feels slippery.
What is a base?
This is the standard pressure at sea level.
What is 1 atmosphere (1 atm)?
During the ice cream lab, this is the type of heat change we experienced as we shook the bag (hint: endo vs exo).
What is exothermic?
This is what a mole is.
What is a counting number (6.022 x 10^23) OR a standard unit of measurement?
This is how you would describe the saturation of a solution of sweet tea that tastes just right.
What is saturated or concentrated?
This is the only substance to have a true neutral pH.
What is water?
This is what happens to the pressure of a gas when the temperature is increased in a fixed container (no change in volume).
What is pressure will increase?
This item produced the greatest quantity of heat energy in the Calorimetry Lab.
What is the marshmallow?
DOUBLE JEOPARDY
This is when you know a chemical reaction has stopped.
What is when the limiting reactant is used up?
This is how you would describe the saturation of a solution of sweet tea that tastes very watery.
What is unsaturated or dilute?
This is what you use in a titration to change color and tell you when the reaction has reached its endpoint (neutral).
What is an indicator?
This is what happens to the pressure of a gas when the volume decreases but temperature remains the same.
What is pressure increases?
1 banana has 439 Joules of energy. This is how many Calories a banana has (4.18 J = Cal).
What is 105 Calories?
The recipe for a s’more is:
2 graham crackers + 1 marshmallow + 1 chocolate piece --> 1 s'more. If you have 9 graham crackers, 10 marshmallow, and 20 chocolate pieces, this is how much of each excess reactant(s) you would have.
What is 1 graham cracker, 6 marshmallows, and 16 chocolate pieces?
This is what happens when water dissolves a salt molecule.
What is water's polar ends attract to the ions in salt and pull them apart?
These are the products of a neutralization reaction (acid and base react).
What is a salt and water?
This is why the pop can was crushed during the Gas Laws Discovery.
What is the atmospheric pressure was higher than the pressure inside the can?
This is how much heat is changed when 150g of water is cooled from 100*C to 30*C. (Remember the specific heat of water is 4.18 J/gC)
What is -43,890 Joules?
