Now, my question is can we write the chemical reaction in the second case as \(CO(g) + H_2(g) \xrightarrow{\triangle}{catalyst} CH_2O\)[product is formaldehyde]

If not, why?

I think all the above four chemical reactions are for commercial production of dihydrogen except last one. But in the first case what is \(M_mO_o(s)\) on the reactant side of the equation? Is it metal oxide?
