Question

1. identify the reaction type shown here.

nacl + agno₃→ nano₃ + agcl
show the reaction types summary table.
single replacement
combustion
no reaction
decomposition
combination
double replacement

Explanation:

In the reaction \( \text{NaCl} + \text{AgNO}_3
ightarrow \text{NaNO}_3 + \text{AgCl} \), the cations (\( \text{Na}^+ \) and \( \text{Ag}^+ \)) and anions (\( \text{Cl}^- \) and \( \text{NO}_3^- \)) of the two reactants exchange places to form new compounds. This matches the definition of a double replacement reaction, where two compounds react by exchanging ions. Single replacement involves one element replacing another in a compound, decomposition is breaking down a compound, combustion involves burning (usually with \( \text{O}_2 \)), combination is forming a single compound from reactants, and there is a reaction here (so "No Reaction" is wrong).

Answer:

Double Replacement (the option corresponding to "Double Replacement" in the choices, e.g., if it's a radio button or checkbox, select the one labeled "Double Replacement")
