What is a mole?
The fundamental unit used to measure the amount of a substance
In a reaction between the elements aluminum and chlorine, aluminum chloride is produced.
Balance the Equation.
2Al +3Cl2 → 2AlCl3
Determine limiting reactant:
carbon ⇒ 3/1 = 3
hydrogen ⇒ 4/2 = 2
Hydrogen is the limiting reactant.
What is a balanced equation?
A chemical equation where the number of atoms for each element is equal on both sides.
How many moles of Cl2 must react to produce 12.3 g of AlCl3?
0.138 mol Cl2
You have 0.4 g H2 and 1.8 g O2 to make water. Which is the limiting reactant in producing water?
Hydrogen is the limiting reactant.
what is a limiting reactant?
The reactant that is completely consumed first, restricting the amount of product formed.
How many grams of aluminum will react with 3.4 moles of chlorine?
61.2 g Al
You mix 100 mL KMnO4 of aqueous 0.100 M KMnO4 with 40 mL of aqueous 0.5 M H2O2 in excess acid. Which is the limiting reactant?
