NR - no reaction
PO3-3 what type is this problem? Type 1 or type 2?
Ra3+2(PO3-3)2
Type 1
calculate #mol H2needed to produce 1.32 mol H2O
2H2(g) + O2(g) 2H2O(g)
2 mol H2
1 mol O2
2mol H2O
1.32 mol H2 (3SF)
we have 6.98 g F2 How many grams of BF3 doe we need?
F2 Flourine atoms 2 x 19.00 = molar mass 38
MM(F2) = 38 g/mol
what is a cation?
an atom or group of atoms that bears a positive electric charge.

CIO2-1 What type is this problem?
Zn2(CIO2-1)2
Type 2
Calculate the #mol NH3 produced if 4.935 mol N2 react
N2(g) + 3H2(g) 2NH3(g)
1mol N2
3molH2
2molNH3
9.870NH3 (4SF)
we have 5.798 mol of Fe2O3 how many moles of Fe are needed for this reaction?
Fe2O3 flourine Fe atoms = 2 x 55.85 = molar mass 111.7
O molar mass #3 x 16.00 =+ 48
MM (Fe2O3) = 159.7 g/mol
what is a mole

19.80AI
(4SF)
what is a limiting reactant?
the reactant that gets consumed first in a chemical reaction and therefore limits how much product can be formed
Cu + H2O
No reaction
AsO3-3
Type 1 or type 2
Os3+2(AsO3-3)2
Type 2
What is a mole ratio
a conversion factor that relates the amounts in moles of any two substances in a chemical reaction.
what is molar mass?
the mass in grams of 1 mole of the substance
what is a conundrum?
a measurement that may be used to separate individual chemicals out of a complex mixture.
