Answer the following questions:
Answer variants:
because light produced is distributed across the body as energy
\(Fe_2O_3\) + \(Al\) → \(2Fe\) + \(Al_2O_3\)
\(CuO\) + \(2HCl\) → \(CeCl_2\) + \(2H_2O\)
\(Fe_2O_5\) + \(Al\) → \(3Fe\) + \(Al_2O_3\)
\(CuO\) + \(2HCl\) → \(CuCl_2\) + \(H_2O\)
1. Complete and balance the following equation: \(Fe_2O_3\) + \(Al\) →
2. On adding dilute hydrochloric acid to copper oxide powder, the solution formed is blue green. Predict the new compound formed which imparts a blue green colour to the solution.
