Final answer:
Chemical reactions were analyzed to predict products - MnCO3 with HI produces MnI2, CO2, and H2O, while La reacts with O2 to create La2O3. The 'Coo' reactant is a likely typo and cannot be accurately assessed.
Step-by-step explanation:
The question revolves around predicting the products of chemical reactions given certain reactants. Here, we are asked about the organic products when HI behaves as an HX reagent reacting with various compounds.
For the reaction MnCO3 (s) + HI (aq), manganese (II) iodide (MnI2), carbon dioxide (CO2), and water (H2O) would be the expected products.
When considering the reaction Coo (s) + O2 (g), the most probable product is cobalt(II) oxide (CoO), even though the original reactant seems to be a typographical error as 'Coo' does not represent a known chemical compound.
The reaction La (s) + O2 (g) will yield lanthanum(III) oxide (La2O3) if La represents lanthanum.
