Step-by-step explanation:
Word Equation
Barium Chloride + Sodium Chromate = Sodium Chloride + Barium Chromate
1 mole of aqueous Barium Chloride [BaCl2] reacts with 1 mole of aqueous Sodium Chromate [Na2CrO4] to form 2 moles of aqueous Sodium Chloride [NaCl] and 1 mole of solid Barium Chromate [BaCrO4]
