Below are the choices that can be found from other sources:
<span>A) elements
B) ions
C) molecules
D) neutrons
the answer is ions.
</span>A Star<span> and hence our Sun, is an almost entirely ionized ball of </span>plasma<span>, consisting of electrons and ions, in which there is hardly any gas (neutral atoms). The movement of the </span>plasma<span> produces strong magnetic fields and corresponding electric currents.</span>
Answer: Crystals are formed by the earth and the earth itself otherwise then its a fake crystal
Explanation:
Every crystal that exists was formed when earth was formed. Take diamonds for example, All diamonds were crushed for millions of years by the earth and that's why they are so valuable. All diamonds are just coal.
So your answer is no but fake crystals yes
Answer: The specific heat of the liquid is 
Explanation:

As we know that,

.................(1)
where,
q = heat absorbed or released
= mass of glass = x kg
= mass of liquid = x kg
= final temperature =
= temperature of glass = 
= temperature of liquid = 
= specific heat of glass = 
= specific heat of liquid= ?
Now put all the given values in equation (1), we get
![-[(x\times 840\times (53-83)]=x\times c_2\times (53-43)](https://tex.z-dn.net/?f=-%5B%28x%5Ctimes%20840%5Ctimes%20%2853-83%29%5D%3Dx%5Ctimes%20c_2%5Ctimes%20%2853-43%29)

Therefore, the specific heat of the liquid is 
That’s tuff, lol stay in school.
It takes 84 years! Hope this helped :)
