WebThe reaction of group 2 metals with oxygen follows the following general equation: 2M (s) + O2 (g) → 2MO (s) Where M is any metal in group 2. We can see this is a redox reaction by looking at the changes in oxidation number of the metal, M, and oxygen. M = 0 → +2 so the metal has been oxidised. O = 0 → -2 so the oxygen has been reduced.

This spectral region is generally subdivided into three portions, near-infrared (14,290 – 4000 cm-1), mid-infrared (4000 – 400 cm-1), and far-infrared (700 – 200 cm-1). The range of numbers represents wave number (cm-1). fly bne to melbourne
