Answer:

The specific gravity of the rock with respect to water is equal to 3

Explanation:

To solve the question, we list out the variables as follows

Mass of rock = 6 grams

Mass of equal volume of water = 2 grams

Specific gravity or relative density is the mass of a unit volume of a substance divided by the mass of an equal volume of a reference material.

Specific gravity = (mass of substance)/(mass of equal volume of water)

Therefore the specific of the rock sample is = (mass of cube of rock sample)/(mass of same-sized cube of water)

= (6 grams)/(2 grams) = 3

The specific gravity of the rock = 3

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.
