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 used to identify it is that two separate reactant compounds (Fe2O3 and SiO2) combine to form a single, more complex product (Fe2Si2O7).

73634

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

Answer:

This chemical equation represents a decomposition reaction. It is identified as decomposition because there is a single reactant (NH4NO3) that breaks down into two separate product substances (N2O and H2O).

73640

Sample Response: This chemical equation represents a decomposition reaction. This identification is based on the fact that the single reactant chemical compound breaks down into two different chemical substances that are different from the initial chemical substance. What did you include in your response? Check all that apply.The reactant is a single chemical substance and reactants are separate substances.The reaction is a decomposition reaction.The reactant breaks down into new chemical substa

A
The reactant is a single chemical substance and reactants are separate substances.
B
The reaction is a decomposition reaction.
C
The reactant breaks down into new chemical substances for products.
