Example 8: If \(H_2O_2\) and Chromium metal undergo a synthesis reaction, what is one possible product of the reaction? Solution: Of course there may be multiple answers, but they all must include Chromium, Hydrogen, and Oxygen. This solution creates an ionic compound; the product \(Cr(OH)_3\) appears perfectly valid, as this is indeed a synthesis reaction by definition.

Calcium Metal - an overview | ScienceDirect Topics

The production process of calcium metal by the metallothermic reduction process (see Equation 2.9.43) is shown in Figure 2.9.43. The raw material CaCO 3 is calcined to produce CaO. Low magnesia content (MgO) is preferred for the reduction feed materials because magnesia is preferentially reduced in this process, thus lowering the reaction efficiency for calcium metal.
