Section B: Give a very short answer to the question given below.
Copper powder is taken in a china dish and heated over a burner. Name the product formed and state its color. Write the chemical equation for the reaction involved.
When copper powder is heated in the presence of air, it reacts with oxygen to form copper oxide. This chemical reaction changes colour, which helps identify the product.
Copper + Oxygen →
Initially, the copper powder is in colour.
When the copper powder is heated, it reacts with oxygen in the air.
The copper (\(Cu\)) reacts with oxygen (\(O_2\)) to form copper(II) oxide (\(CuO\)), which is in colour.
The reaction is represented by the equation: \(2Cu\)(𝑠) + \(O_2\)(𝑔) → \(2CuO\)(𝑠).
