The reaction shown is a synthesis reaction, specifically a form of a combination reaction, where two or more reactants combine to form a single product.
Clues Used to Identify the Reaction Type:
-
Reactants and Products: The reaction presents two reactants (Fe2O3 and SiO2) that combine to form a single product (Fe2Si2O7). This is a key characteristic of a synthesis reaction, as it involves combining multiple substances into one.
-
Chemical Composition: The reactants are both oxides (iron(III) oxide and silicon dioxide), and they yield a compound (ferrous disilicate) that incorporates elements from both reactants. This indicates that elements are being combined rather than being broken down or replaced, as in other reaction types.
-
Stoichiometry: The balanced equation shows that stoichiometric coefficients indicate a specific mole ratio for the reactants to yield the product. This balance is typical of a synthesis reaction, as it reflects the straightforward combination of reactants.
In summary, the formation of one product from two reactants is a primary indicator of a synthesis reaction, making this reaction identifiable as such.
