Stoichiometry
Methane+Oxygen
CH4+202----->CO2+2H20
Your first step is Balancing your equation.
Balancing Equation
Balance your equations by making sure you have to same amount of each element on both sides.
first look
We must first find the imbalances in the equation, which in this case are H and O
Step 2
After we fix the imbalance for H, we find that O is also imbalance so we fix that.
Complete
Now it is all balanced
Naming Elements
CH4 - Methane
O2 - oxygen
CO2 - carbon dioxide
H2O - water
Molar Mass's
CH4 - 16.1g/mol
O2 - 64g/mol
CO2 - 44.01g/mol
H2O - 36 g/mol
Mole to Mole
if you are given 12.1 moles of Methane, then how many moles of water can you get?
Mass to Mass
How much water can you get with 12.1g of Methane?
Limiting & Excess Reactants
12.1 - Methane
20.15 - Oxygen
? - Water
Theoretical Yeild
This is equal to our limiting factor = 11.33g
Percent Yield
If you do the reaction and come up with 6.5g of H2O, what is the percent yield?
