Element z reacts with bromine to form an ionic compound zbr2. a) state with reasons i) the physical properties of zbr2 at room temperature ii) whether z is a metal or non metak.

The answer to your question is:

Explanation:

A) state with reasons

From the description we can conclude that the compound is a binary salt. Binary salts are form by a metal and a non metal, one of their characteristics is that the elements are attached by an ionic bond.

i) the physical properties of ZBr2 at room temperature

Crystals, high fusion and boiling points, they conduct water when dissolved in water, they are soluble in water but not in gasoline.

ii) whether z is a metal or non metal.

Z is a metal

they are all solids.
