The correct answer is: -3 (minus three)
Explanation:
To find the overall charge, we add electrons and protons. Make sure that you use the negative sign for an electron and positive sign for proton.
There are 10 electrons. It means the charge is "-10"
There are 7 protons. It means the charge is "+7"
Add both of them:
+7 - 10 = -3
Therefore the overall charge on this ion is -3.
Answer:
The more polar bond is C-O.
Explanation:
The greater polarity is due to that the Oxygen atom is more electronegative than the Nitrogen atom, so the negativity of the molecule tends to be on that side.
Answer:
Plasma.
Explanation:
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;
I. Solid.
II. Liquid.
III. Gas
Plasma can be defined as a state of matter in which the electrons temporarily separate from the protons and as a result, it is generally referred to as the fourth (4th) state of matter due to its superheated nature.
16 tiles x 0.80 = $12.80
If you have two 100 dollar bills, you have 200 dollars.
$200 - $12.80 = $187.20
Answer:
Y is a 3-chloro-3-methylpentane.
The structure is shown in the figure attached.
Explanation:
The radical chlorination of 3-methylpentane can lead to a tertiary substituted carbon (Y) and to a secondary one (X).
The E2 elimination mechanism, as shown in the figure, will happen with a simulyaneous attack from the base and elimination of the chlorine. This means that primary and secondary substracts undergo the E2 mechanism faster than tertiary substracts.
