A tetravalentelement formsmonoxide and disoxidewit oxygen. When air is passed over heated element (1273 K). Producer gas is obtained. Monoxide of the lement is a powerful reducing agent and reduces ferric oxide to iron. The element and write formulas of its monoxideand dioxide. Write chemicalequationsfor the formationof producera gas and reduction if ferric oxidewith the monoxide.
