You are working in the laboratory, preparing NaCl, sodium chloride. Consider the following results for three preparations of the compound:
Reaction 1: 39.34 gNa + 60.66 gCl₂ → 100.00 gNaCl
Reaction 2: 39.34 gNa + 70.00 gCl₂ → 100.00 gNaCl + 9.34 gCl₂
Reaction 3: 50.00 gNa + 50.00 gCl₂ → 82.43 gNaCl + 17.57 gNa
Explain these experimental results in terms of the fundamental laws. Which laws are obeyed in these experiments?
