Chapter 3: Stoichiometry Flashcards
1
Q
x –> x
A
reactants –> products
2
Q
What is the limiting reactant
A
Runs out first
(Limits the amounts of products that can be formed)
*reaction that produces the smallest amount of product
3
Q
What is the theoretical yield
A
Amount of product formed after the limiting reactant is entirely consumed
*Amount of product predicted is rarely obtained
4
Q
Percent yield
A
Actual yield of product
5
Q
Standard temperature and pressure (STP) conditions
A
- 0 C (273 K)
- 1 atm
- 22,4 L
6
Q
Ideal gas law
A
PV=nRT
7
Q
Law of partial pressures
A
Ptotal = P1+ P2 + P3 +…
8
Q
What is partial pressure
A
Pressure that a gas would exert if it were alone in a container
9
Q
Vapour pressure of water
When the rate of escape of a gas in a container = the rate of return:
A
- Number of water molecules in the vapor state remain constant
- Pressure of water vapor remains constant
