Answer:

The answer to your question is: b) Chemical property

Explanation:

Physical property: is when matter changes is physical state but it does not change its composition. For example, evaporation, condensation, sublimation,  solidification, etc.

Chemical property, is when matter changes its composition because the reactants forms products.

In this question we have:

                                         Mg    +       HCl      ⇒      MgCl₂ + H₂↑

In this reaction, there are Mg and HCl, and after the reaction MgCl₂ and H₂ so, there was a change, and this reaction is a chemical change.

Consider the perbromate anion. What is the central atom? Enter its chemical symbol. How many lone pairs are around the central a
Yanka [14]

Answer:

See explanation

Explanation:

The central atom in the perbromate ion is bromine. The chemical symbol of bromine is Br. There are no lone pairs around the central bromine atom. The ion is tetrahedral in shape hence we expect a bond angle of 109°. 27 which is the ideal tetrahedral bond angle. The actual bond angle of the prebromate ion is 109.5°. The perbromate ion is BrO4^-

The observed bond angle is very close to the ideal value because of the absence of lone pairs of electrons from the central atom in the ion.
