Answer:

Beginning from the innermost layer and moving towards the outermost of the sun that has six layers.

1. Innermost layer is the core: All the energy of the sun comes from core. Here hydrogen and helium are components that are present.

2. Radiative zone: The high-energy photons are move from the innermost core to the second innermost radiative zone.

3. Convective zone: It is a comparatively cooler layer to the core and radiative zone.

4. Photosphere: It is the 4th innermost region with sunspots and called the magnetic field of the sun.

5. Chromosphere: This red color layer with filaments of gas is cooler than the photosphere.

6. Corona: It is the outermost layer of the sun and the temperature is much higher here.

Classify each of the four compounds as a conjugated, isolated, or cumulated diene. Compound A: Two alkenes are joined by a sigma
Lina20 [59]

Explanation:

Conjugated diene is the one that contains alternate double bonds in its structure. That means both the double bonds are separated by a single bond.

Cumulated diene is the one that contains two double bonds on a single atom. This means it has two double bonds continuously.

Isolated double-bonded compound has a single bond isolated by two to three single bonds.

Compound A: Two alkenes are joined by a sigma bond.

For example:

-CH_2=CH-CH=CH2-

It is a conjugated diene.

Compound B: Two alkenes are joined by a C H 2 group.

It is a cumulative diene.

Compound C: Two alkenes are joined by C H 2 C H 2.

Then it is an isolated alkene.

Compound D:  A cyclohexene has a double bond between carbons 1 and 2. Carbon 3 is an sp 2 carbon that is bonded to another s p 2 carbon with an alkyl substituent.

Hence, compound D is a conjugated diene.

3. 200 ml of 0.2 M HCl is neutralized with 0.1 M
algol [13]

Answer:

  • <u><em>a. 0.1 M</em></u>

Explanation:

By definition, <em>half neutralization</em> is the point at which half of the acid has been neutralized.

The neutralization reaction that you are studying is the acid-base reaction:

  • HCl (aq) + NaOH (aq) → NaCl(aq) + H₂O (aq)

Then, since the starting molarity of the acid (HCl) is 0.2 M, you just need to find half of that concentration:

  • Half molarity = M / 2 = 0.2 M / 2 = 0.1 M

So, the answer is the first choice: a. 0.1 M.
