Question

Complete the following equation

1. Iron + Oxygen +Water = ?
2. Magnesium + Oxygen = ?
3. Copper sulphate + Zinc =?​

Answer 1

Explanation:

1. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Boiling the water removes the oxygen and the layer of oil prevents it from re-entering.

2. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. ... Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product.

3. solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless. The chemical equation of the reaction, Zn + CuSO4 → ZnSO4 + Cu.

Answer 2

Answer:

1. iron oxide

2. magnesium oxide

3. zinc sulphate+copper
