Answer:
Niels Bohr
Explanation:
Niel’s Bohr described the atomic model. He in his model showed that an atom is a small positively charged nucleus. Around the positively charged nucleus, electrons orbit in separate orbits.
The electrons in the outermost shell are responsible for the properties associated with an element.
The electrons at different shells have different energy. When an electron jumps from a shell of higher energy to a shell of lower energy, energy is released.

The answer to “what is 45 divided by 5.6” is 8.04.
Answer:
K = [HI]² / [H₂] [I₂]
Explanation:
To write the expression of equilibrium constant, K, it is important that we know how to obtain the equilibrium constant.
The equilibrium constant, K for a given reaction is simply defined as the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient. Thus, the equilibrium constant is written as follow:
K = [Product] / [Reactant]
Now, we shall determine the equilibrium constant for the reaction given in the question above. This can be obtained as illustrated below:
H₂(g) + I₂(g) —> 2HI (g)
K = [HI]² / [H₂] [I₂]
