it is chemical change because chemical change occur when bonds are broken or formed between molecules or atoms.
<span> aluminum is an element. All elements are pure substances, so that means they are homogenous.

An electron in a hydrogen atom would have 10 states for a 3d orbital, like any other element.
n = 3, l = 2, in one of ml = 2, 1, 0, -1, -2 each with ms = -½ or +½ or a total of 10 possible states.
None of these are a ground state of an electron in the hydrogen atom.
Enjoy :)
Answer:
The correct answer is skeleton equation.
Explanation:
In chemistry, the skeletal formula of a compound is an abbreviated representation of its molecular structure. Skeleton formulas are used because they clearly show complicated structures, they are fast and simple to draw.
All atoms that are not carbon or hydrogen are represented by their chemical symbol. The relative amounts of reagents and products are not indicated.
Have a nice day!
In the following choices, all of the above are an end product of fractional distillation except for one. The ones that are the end product of fractional distillation are, asphalt, heating oil and kerosene. Crude petroleum is not an end product of fractional distillation, so the correct answer is letter A.
