What is step one?
You need to balance the equations
100
what is Stoichiometry
The study of quantitative relation between reactents and products in a chemical reaction.

WHat is Molecular mass?
the mass of atomic mass units of ne molecule .
100
Balance the eqn: Ca3P2 + H2O --> Ca(OH) 2 + PH3
1 Ca3P2 + 6H2O--> 3 Ca(OH)2 + 2 PH3

Descrive the relationships between mass and moles
mass and moles are the amount of material and are normolaized to the atomic mass of that material.
200
Wha is step two?
convert given variable to moles with a conversion factor
200
what is mole
The group of measurements:use to count numbers of atoms molecules, and ions.
200
What is Molar Volume?
It is the volume that mole of gass occupies at the pressure of one atmostphere and the temperature of zero* celcious.
200
Balance Equation: n2 (g) + H2O (g) --> NH3 (g)
1N2 + 3H2O--> 2NH3
200
Can mass and grams be converted directly to number of particles
no
300
WHat is step 3?
Use coefficients as a converion factor to convert moles of given-to moles of desired ;)
300
What is Avogadro's Number
6.02*10(23)

What is the ideal gas law?
it is the behavior of an ideal gas in temrs of presurre, P, volume,V, temperature, T, and Number of moles, N.
300
balance: CO2 (g) + H2(g)--> Ch3OH (l) + H20 (g)
1CO2 + 3H2--> CH3OH + H2O
300
Why is the number of any magnism metal not equal to the number of moles of any lead metal ?
Because they have a different mass
400
What is step five?
Convert to desired variables using a converstion factors
400
What is molar mass
Mass of one mole of a pure substance
400
Theoretical yield
the amount of product of a chemical reaction predicted by stoichiometry.
400
balance: FeS2 + 02--> FeO + SO2
2FeS2 + 5O2--> 2FeO + 4So2

How many liters is a gas equal to at STP?
22.4 Liters

what is formula mass?
mass in atomic mass unit of one formula unit
500
Percent yield
The ratio of the actuall yield to the theoretical yiels express as a percent.
500
CO2 (g) + LiOH (s) --. Li2CO3 (s) + H20
1 Co2+ 2LiOH--> Li2CO3 + H20
