Question

silver nitrate reacts with beryllium in a single replacement reaction. agno₃ + be → what are the products for the reaction? beno₃ + ag agbe + no₃ be(no₃)₂ + ag ag₂be + no₃

Explanation:

Step1: Understand single - replacement reaction

In a single - replacement reaction \(A + BC
ightarrow AC + B\). Here, \(A = Be\), \(B = Ag\), \(C=NO_3\).

Step2: Determine the charge of ions

The charge of \(Be\) is \(+ 2\) (beryllium is in group 2 of the periodic table), and the charge of \(NO_3^-\) is \(-1\). To form a neutral compound, we need two \(NO_3^-\) ions for each \(Be^{2 +}\) ion. So the formula for beryllium nitrate is \(Be(NO_3)_2\). And silver is produced as a free element \(Ag\).

Answer:

\(Be(NO_3)_2+Ag\) (the third option)
