Explanation:
The main task here is that there are some missing gaps in the above question that needs to be filled with the appropriate answers. So, we are just going to do rewrite the answer below as we indicate the missing gaps by underlining them and making them in bold format.
SO; In the quantum-mechanical model of the hydrogen atom.
As the n level increases. the energy <u>increases</u> and thus levels are <u>closer to </u>each other. Therefore, the transition <u>3p→2s</u> would have a greater energy difference than the transition from <u>4p→3p.</u>
With what are you need help?
Answer:
<em> The answer is </em><u><em>(D) Magnetism</em></u>
The methods separates a homogeneous solution by spinning the solution very fast is magnetism.
The product Bismuth (III) sulfide (
) is used as a starting material for the synthesis of other bismuth compounds. It is formed, together with an acid, from a reaction between a Bismuth (III) salt and hydrogen sulfide (
). In the given reaction, the Bismuth salt used in the reaction is Bismuth (III) chloride (
).
The balanced reaction of
and
is
Thus, the coefficient of HCl in the reaction is 6.
Answer:
Oxygen gas
Explanation:
It is a pure element. The rest are compounds made up of two or more elements. For eg silicon dioxide is made of silicon and oxygen.
