Sodium and chlorine react to form sodium chloride: 2Na (s) + Cl2 (g) ----> 2NaCl (s) For the reaction of 44.0g Na with 69.9 g Cl2, what is the limiting reactant and what is the theoretical yield of sodium chloride in grams?
The limiting reactant is
This is a limiting reactant problem.
We know that we will need a balanced equation with masses, molar masses, and moles of the compounds involved.
1. Gather all the information in one place with molar masses above the formulas and everything else below the formulas.
2. Identify the limiting reactant
An easy way to identify the limiting reactant is to calculate the "moles of reaction" each reactant will give:
You divide the moles of each reactant by its corresponding coefficient in the balanced equation.
I did that for you in the table above.
3. Calculate the theoretical moles of
4. Calculate the theoretical yield of
