That would be the cobalt(11) Chloride Hexahydrate
Answer:
The correct answer is : It is a salt because it is formed by the reaction of an acid and a base.
Explanation:
Sodium chloride is formed from the neutralization reaction between a strong acid (hydrochloric acid) and a strong base (sodium hydroxide):
HCl + NaOH ---> NaCl + H20
By reacting strong acid and base, they neutralize each other resulting in a salt (NaCl) and water.
Corresponds to an exothermic reaction (heat is released).
Answer:
