Identify the reaction type shown and describe the clues that were used to identify it.Fe2O3 + 2SiO2 → Fe2Si2O7

Answer:

This is a synthesis reaction. The clue for identifying it as a synthesis reaction is that two separate chemical compounds (Fe2O3 and SiO2) combine to form a single product (Fe2Si2O7).

Identify the reaction type shown and describe the clues that were used to identify it.NH4NO3 → N2O + 2H2O

Answer:

The chemical equation NH4NO3 → N2O + 2H2O represents a decomposition reaction. This is identified by the fact that there is a single reactant (ammonium nitrate) breaking down into two different products (nitrous oxide and water).
