Please I need help.
Write the expression for the equilibrium constant Keq for the reaction below:

2KClO3(s) ⇔ 2KCl(s) + 3O2(g)

a.[KClO3] / [KCl] [O2]

b. [KClO3]2 / [KCl]2 [O2]3

c. [KCl] [O2] / [KClO3]

d. [KCl]2 [O2]3 / [KClO3]2

Answer choise.

d

c

a

b

Ithink it’s 3 as the answer.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
