What is the sun internal structure of the sun?

1 answer:

5 0

I hope this helps you...

From the center out, the layers of the Sun are as follows: the solar interior composed of the core (which occupies the innermost quarter or so of the Sun's radius), the radiative zone, and the the convective zone, then there is the visible surface known as thephotosphere, the chromosphere, and finally the outermost layer, the corona.

Which of the following is true about a spontaneous process? it releases energy, it does not require any external action to begi,

ra1l [238]

Answer: Option (b) is the correct answer.

Explanation:

A spontaneous reaction is defined as the process which tends to occur on its own. It does not require any external factor or force in order to start itself.

For example, when we dissolve KCl in water then potassium chloride being ionic in nature will dissolve on its own. Hence, it will be a spontaneous process.

And, a non-spontaneous reaction is defined as a process for the completion of which we have to provide certain conditions.

Thus, we can conclude that the statement it does not require any external action to begin, is true about a spontaneous process.

A hydrated salt is a solid that includes water molecules within its crystal structure. A student heated a 12.10-gram sample of a

sveticcg [70]

Answer : The percent by mass of water the salt contain is, 55.3 %

Explanation : Given,

Mass of hydrated salt = 12.10 g

Mass of salt = 5.41 g

First we have to calculate the mass of water.

Mass of water = Mass of hydrate salt - Mass of salt

Mass of water = 12.10 g - 5.41 g

Mass of water = 6.69 g

Now we have to calculate the percent by mass of water the salt contain.

$\text{Percent by mass of water}=\frac{\text{Mass of water}}{\text{Mass of hydrate salt}}\times 100$

Now put all the given values in this expression, we get:

$\text{Percent by mass of water}=\frac{6.69g}{12.10g}\times 100$

$\text{Percent by mass of water}=55.3\%$

Therefore, the percent by mass of water the salt contain is, 55.3 %
