​

Answer 1

Answer:

Question: Explain the steps involved in the extraction of copper from its sulphide ore.

Answer:In the extraction of copper from its Sulphide Ore when ore is subjected to roasting some of it is oxidised to Cu2O which reacts with the remaining Cu2S to give copper metal. In this process Cu2S behaves as reducing agent.

Explanation:

Question:Write the

balanced equations involved.

Answer:Examples of balanced chemical equation

Example 1: Balancing Chemical Equations

N2+O2→N2O5(unbalanced) N 2 + O 2 → N 2 O 5 (unbalanced)

N2+5O2→2N2O5(unbalanced) N 2 + 5 O 2 → 2 N 2 O 5 (unbalanced)

2N2+5O2→2N2O5 2 N 2 + 5 O 2 → 2 N 2 O 5.
