However, if this happens, there can be no stable isotope with an even number of neutrons and an even number of protons. Hydrochloric acid (HCl) and Sodium hydroxide(NaOH) Acid reacts with base to form salt and water.This type of reaction is called acid base neutralization reaction. Today, technetium is produced by bombarding molybdenum-98 with neutrons. Now see all the steps at a glance. Hydrochloric acid reacts with sodium hydroxide and produce sodium chloride(NaCl) and water(H₂O).Here sodium chloride(NaCl) is a salt beacause its positive part (Na+)has come from base and negative part(Cl-) has come from acid. Sulfuric acid is an acid because it has hydrogen ion.The formula for sulfuric acid is H₂SO₄.It is a strong acid.    Noble Gases CO Lewis Structure Before we begin,can you tell me how many valence electrons does C and O atom have?
