What salt is formed by the reaction of potassium hydroxide and hydrochloric acid?

potassium chloride

Explanation:

Double displacement reaction is one which involves exchange of ions. Neutralization is a type of double displacement reaction in which an acid combines with a base to form salt and water, the reaction is called as neutralization reaction.

Thus the salt formed is potassium chloride which has the chemical formula .

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

answer: a chemical reaction
