The salt that is formed during the reaction between potassium hydroxide and hydrochloric acid is

Sodium chloride (NaCl)

Explanation:

According to Arrhenius, an acid is a substance that dissociates to give protons, whereas a base dissociates to give hydroxide ions in an aqueous solution.

Therefore, a chemical reaction in which an Arrhenius acid reacts with an Arrhenius base to give salt and water, is known as a Neutralization reaction.

For example: Neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH)

A strong acid, hydrochloric acid (HCl) reacts with a strong base, sodium hydroxide (NaOH) to give salt, sodium chloride (NaCl) and water (H₂O).

The chemical equation for this Neutralization reaction:

HCl (acid) + NaOH (Base) → NaCl (Salt) + H₂O (Water)

Therefore, sodium chloride (NaCl) is the salt formed during the chemical reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH).

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
