Match the correct chemical reaction to the corresponding metal.
Answer variants:
\(2Al\) + \(3H_2SO_4\) → \(Al_2(SO_4)_3\) + \(3H_2\)↑
\(2Cu\) + \(O_2\) → \(2CoO\)
\(3Cu\) + \(8HNO_3\) → \(3Cu(NO_3)_2\) + \(2NO\)↑ + \(4H_2O\)
\(Fe\) + \(2HCl\) → \(FeCl_2\) + \(H_2\)↑
\(2Fe\) + \(3Br_2\) → \(2FeCl_3\)
\(2Al\) + \(N_2\) → \(2NIA\)
