The figure shows the skeletal structure in line-angle (line-bond) mode of 2,5-dimethylhexa-1,4-diene. Identify the number of

deff fn [24]

Answer:

There are 22 hydrogen in 2,3,3,5-tetramethylhexane (C10H22)

From the left to the right of the skeletal structure:

1st Main Carbon = 3 hydrogen

2nd Main Carbon = 1 hydrogen

1st Branch Carbon = 3 hydrogen

3rd Main Carbon = 2 hydrogen

2nd Branch Carbon = 3 hydrogen

3rd Branch Carbon = 3 hydrogen

4th Main Carbon = 0 hydrogen

4th Branch Carbon = 3 hydrogen

5th Main Carbon = 1 hydrogen

6th Main Carbon = 3 hydrogen

Total = 22 hydrogen

Explanation:

This is the skeletal formula for 2,3,3,5-tetramethylhexane - the 2D chemical structure. It is an organic compound. The carbon atoms in the structure are known as the carbon backbone. The hydrogen atoms are linked to the carbon backbone. This provides each carbon atom with four bonds.

The quinine in tonic water shines a strange blue-white colour when lit with UV light. Explain what is happening here.

Alecsey [184]

Answer:

Here's what I get.

Explanation:

Quinine contains phosphors, substances that glow when they are hit with certain wavelengths of light.

The phosphors in quinine absorb UV light, which is invisible to our eyes.

Electrons in the phosphors absorb the UV energy and are excited to higher energy levels.

When the electrons drop back to lower energy levels, they emit some of this energy as a glowing blue visible light.

finlep [7]

Answer:

Se detailed explanation.

Explanation:

Hello,

In this case, since both magnesium and calcium ions are in group IIA, we can review the following similar properties:

- Since both calcium and magnesium are in group IIA they have two valence electrons, it means that the both of them have two electrons at their outer shells.

- They are highly soluble in water when forming ionic bonds with nonmetals such as those belonging to halogens and oxygen's family.

- Calcium has 18 electrons and magnesium 10 which are two less than the total protons (20 and 12 respectively) since the both of them have lost two electrons due their ionized form.

- Their electron configurations are:

$Ca^{20}=1s^2,2s^2,2p^6,3s^3,3p^6,4s^2\\\\Mg^{12}=1s^2,2s^2,2p^6,3s^2$

It means that the both of them are at the $s$ region since it is the last subshell at which their electrons are.

Best regards.
