Answer:
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
Element Z reacts with bromine to form an ionic compound ZBr₂. (i) The physical properties of ZBr₂ at room temperature is that bromine has red brown color and (ii) Z is metal as bromine belongs to halogen family.
The chemical compounds which is made up of ions that formed charged particles when a atom or a group of atoms lose or gains electrons is called Ionic Compound.
(i) The physical properties of ZBr₂ at room temperature.
Bromine is a liquid at room temperature due to strong intermolecular forces so that bromine does not evaporate. The physical properties of ZBr₂ at room temperature is that bromine has red brown color. It has pungent odor.
(ii) Whether Z is metal or non-metal.
As bromine belongs to halogen family. Halogen group reacts with metal to form metal halide. So Z is a metal.
Thus, from above conclusion we can say that the (i) The physical properties of ZBr₂ at room temperature is that bromine has red brown color and (ii) Z is metal as bromine belongs to halogen family.
