Balancing Chemical Equations WEEK 3 1. Sodium bromide reacts with calcium chloride to form sodium chloride and calcium bromide. Which of these chemical reactions represents the balanced reaction? a. NaBr + CaCl2 → NaCl + CaBr2 b. 2 NaBr + CaCl2 → 2 NaCl + CaBr2 c. NaBr + 2 CaCl2 → NaCl + 2 CaBr2 d. NaBr + CaCl → NaCl + CaBr Balanced chemical equations have the same number of each atom on each side of the arrow. This equation is correct: 2 NaBr + CaCl2 2 → NaCl + CaBr2 2. The...
