Answer:
An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity, the more an atom or a substituent group attracts electrons.

Hope this helps :)
Heating the solid is the answer
Ionic bonds involve the transfer of electrons from metal to non metal
covalent bonds involve sharing of electrons between two non metal
Answer:
E. Fracking
Explanation:
The process involves the high-pressure injection of 'fracking fluid' into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely.
Answer:
The pH of the resulting solution will be 7.
Explanation:
Sodium chloride is a salt that is formed from the reaction of sodium hydroxide (a strong base) and hydrochloric acid ( a strong acid), as shown below.

Generally, when strong acids react with strong bases, neutral salts and water are formed. Sodium Chloride (NaCl) is an example of such neutral salts formed.
Since sodium chloride (NaCl) is neutral, its concentration will not alter the pH of the water and the pH of the resulting solution will be 7.
