konstantin123 [22]

Answer: NH4)2CO3

Explanation:

Ionic solids are the solids that are simply held together by ionic bonds. Ionic bonds are lattices that are typically made up of oppositely charged ions and they usually possess a high melting point.

An example of ionic bond is NH₄)₂CO₃ which is referred to as Ammonium carbonate. This is a salt and it readily degrades upon heating to carbon dioxide and gaseous ammonia.

The diameter of a chlorine atom is 200. pm. How many chlorine atoms are required to line up end to end to stretch a distance of
BartSMP [9]

The number of chlorine atoms needed would simply be the ratio of distance and diameter. But first convert 200 pm to mm:

<span>200 pm = 2 E-7 mm              </span>

So the number of chlorine atoms needed is:

<span>1.0 mm / (2 E-7 mm) = 5,000,000 Chlorine atoms = 5 E6 atoms</span>
