If 56 g of k is reacted with 56 g of oxygen gas according to the equation below, indicate the mass of product that can be made and identify the limiting reactant.
4k(s)+O₂-->2K₂O(s)
a. 68g K₂O;K is the limiting reactant
b. 270g K₂O;K is the limiting reactant
c. 270g K₂O;O₂ is the limiting reactant
d. 68g K₂O;O₂ is the limiting reactant
