Question

what are the products of this reaction? cu + agno₃ -> cuno₃ + ag cu(no₃)₂ + ag cuag + no₃ cu + agno₃

Explanation:

Step1: Determine the type of reaction

This is a single - displacement reaction. In a single - displacement reaction, the general form is \(A+BC
ightarrow AC + B\), where \(A\) is a more reactive metal than \(B\). Copper (\(Cu\)) is more reactive than silver (\(Ag\)) according to the activity series of metals.

Step2: Write the chemical formula of the products

When \(Cu\) reacts with \(AgNO_3\), \(Cu\) will displace \(Ag\) from \(AgNO_3\). The charge of \(Cu\) in the compound is \(+ 2\) (copper commonly has a \(+2\) oxidation state in such reactions), and the nitrate ion \((NO_3^-)\) has a charge of \(-1\). So the formula of copper nitrate is \(Cu(NO_3)_2\), and the displaced metal is \(Ag\).

Answer:

\(Cu(NO_3)_2+Ag\) (the second option \(Cu(NO_3)_2 + Ag\))
