5. Hydrochloric Acid + Sodium Hydroxide à Sodium
Chloride +

HCl Acid + Sodium Hydroxide > Sodium  Chloride + water.

Explanation:

The reaction between an acid and a base is known as a neutralization reaction. The reaction of an acid with a base to give salt, water and heat is called neutralization. When hydrochloric acid reacts with sodium hydroxide, sodium chloride and water are produced.  

                             HCl + NaOH → NaCl + H2O + Heat

The heat evolved in the neutralization reaction raises the temperature of the reaction mixture.    An electro-electrodialysis process (EED) is utilized to create HCl and NaOH from exchange NaCl. NaOH and HCl arrangements with purity higher than 99.9% are acquired. The experimental estimations of the transitions for HCl and NaOH are contrasted and values determined from the incorporation of the Nernst–Planck electro dispersion conditions.

The population of unionid mussels decreased after zebra mussels were introduced. zebra mussels competed with the unionid mussels for food. the zebra mussels were able to displace the unionid mussels, allowing the zebra mussel population to increase  over the years. the unionid mussel population decreased because  of lack of food.
