Question

Element z reacts with bromine to form an ionic compound zbr2. A) state with reasons i) the physical properties of zbr2 at room temperature , deduce the charge on the Z in the compound

Answer 1

Step-by-step explanation:

Ionic compound generally have very similar physical properties. The following are the likely physical properties of the compound because it is an ionic compound:

1. They are usually hard solids with high melting points or liquids with high boiling points.
2. They are soluble in water because they are polar compounds.
3. Their aqueous or molten forms conducts electricity due to the free mobile ions they produce.
4. They are involved in fast reactions.

B. The charge on the Z in the compound is +2;

In ZBr₂:

ZBr₂ → Z²⁺ + 2Br⁻

The charge on Z is 2+
