Stoichiometry
The mole ratio comes from this type of number. (subscripts, superscripts, or coefficients)
What are coefficients?
Name of formula used to relate changing temperature, volume, and pressure.
What is the combined gas law?
SI unit for temperature.
What is Kelvin?
Describe the relationship between temperature and volume.
What is increasing temperature increases volume?
Changing the subscript in a chemical equation changes...
What is the chemical compound?
SI unit for pressure. (Torr, mmHg, Pascal, or atm)
What is Pascals?
The name of the reactant used up first in chemical reactions. AKA least amount of product (excess reactant or limiting reactant)
What is the limiting reactant?
Rearrange the Combined Gas Law to solve for T1. Variables are temperature and pressure.
What is T1 = T2 P1/P2
31°C in Kelvin
What is 304 K?
The reason you shouldn't put cans of shaving cream in a fire.
What is particles move faster from increased temperature, have more collisions until the pressure bursts the container open (increase temp = increase pressure)?
Mole ratio between O2 and Co2:
2 C4H10 + 13 O2 ---> 8 CO2 + 10 H2O
What is 13 mol/8 mol?
The two variables that are directly proportional with temperature.
What is pressure and volume?
The name of the reactant that is leftover after the reaction has stopped AKA most amount of product.
What is the excess reactant?
1.36 atmospheres converted to mmHg.
What is 1033.6 mmHg?
The lowest possible temperature (with units) and its special name.
What is Absolute Zero, 0K (-273°C)?
The reason your tire pressure is low on a chilly morning.
What is decreased temperature, particles moving slower, so fewer collisions and lower pressure.
Mole ratio between H2O and CO2:
2 C4H10 + 13 O2 ---> 8 CO2 + 10 H2O
What is 10 mol/8 mol
The two variables that are inversely related to each other.
What pressure and volume?
You need to make a peanut butter sandwich. You have 2 pieces of bread and 1 jar of peanut butter. What is the limiting reactant and excess reactant?
What is limiting reactant: bread, excess reactant: peanut butter?
The new volume of 2L of a gas if the pressure is decreased from 15 to 5.
What is 6L?
100 K expressed in °C.
What is -173°C?
What is the pressure increases?
2 C4H10 + 13 O2 ---> 8 CO2 + 10 H2O
When 7 moles of water is formed, how many moles of oxygen (O2) were used?
What is 9.1 moles of O2?
Equation with constant amount of pressure from the combined gas law.
What is Charles’ Law: T1 V2=T2 V1?
You're planting flowers. You have 3 flowers and 5 flower pots. Explain why flowers are the limiting and flower pots are the excess reactants
What is limiting reactant: flowers = make least amount of product. Excess reactant: pots = have leftovers at end?
The final pressure of a sealed container at 150kPa if the temperature is doubled from 100°C to 200°C.
What is 190 kPa?
The reason we use the Kelvin scale.
What is there are no negative numbers?
Create a scenario that relates pressure and volume.
Open response, ex: crush a chip bag = pops
Fe2O3 + 3 C ---> 2 Fe + 3 CO
If 25.0 moles of pure Fe2O3 is used, how many moles of iron (Fe) can be produced?
What is 50 moles of Fe?
152 kPa converted to atmospheres.
What is approximately 1.5 atmospheres?
