Write balanced molecular equation for the reaction between hydrobromic acid and potassium hydroxide.
express your answer as a chemical equation. identify all of the phases in your answer.

The balanced equation for this neutralization reaction is:

⇒

Explanation:

Hydrobromic acid is a strong acid. It is produced by dissolving hydrogen bromide (HBr) in water. Thus, its phase is aqueous (aq).

Potassium hydroxide is a strong base, usually commercialized as colorless pellets (s), but could be easily dissolved in water to ease the reaction, that is why it will be considered aqueous for this reaction.

The reaction between an acid and a base is called neutralization reaction, and it produces liquid water (l) and salt, as follows:

    ⇒

We can check that this equation is balanced since it has the same amount of each element on both sides of the equation:

⇒    

K:   0      +      1       =       1      +      0

Br:   1       +     0       =       1      +      0

H:   1       +     1        =       0     +      2

O:    0      +     1        =       0     +      1

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
