Question
Consider the balanced chemical equation:4 B(s) + 3 O2(g) --> 2 B2O3(s)
If 2 moles of B and 3 moles of O2 react, choose the correct statement. Select one: A. B is the limiting reactant because there is less moles before the reaction. B. O2 is the limiting reactant and will produce 2 moles of product. C. Both reactants produce the same amount of product, so the limiting reactant cannot be determined. D. B will be the limiting reactant and will produce 1 mole of product. Consider the balanced chemical equation:

Explanation / Answer
4 B(s) + 3 O2(g) --> 2 B2O3(s)
this can be written as:
2 B(s) + 3/2 O2(g) --> B2O3(s) (after dividing both sides by 2)
2 moles of B require 3/2 moles of O2 to give 1 mole of B2O3.
D)B will be the limiting reactant and will produce 1 mole of product.
