Answer: All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets. environment.
Explanation:
In 1897 the theory of understanding the energetics and arrangement of atoms was developed by Josheph Larmor.
It is also called solar system model of atom.
<h3>What is solar system model of atom? </h3>
The “solar system” model indicates an atom as a whole massive positive body that is the nucleus similar to the sun in the solar system with negative entities that are the electrons as the planets in our solar system revolving around it.
<h3>Why this model not accepted? </h3>
The thought about this model is that the electrons which revolves around the nucleus are the charged particles which have centripetal acceleration during the revolution. Even if they all are travelling at the same velocity in modulus, the trajectory of their velocity varies with respect to time which resulting in the centripetal acceleration. An accelerated charge particle will emit energy in the form of electromagnetic radiation. This results in the loss of energy which causes the charged particle to fall inside the nucleus. Therefore, this fails to happen.
Thus, we concluded that In 1897 the theory of understanding the energetics and arrangement of atoms was developed.

When adjusted for any changes in δh and δs with temperature, the standard free energy change δg∘t at 2400 k is equal to 1.22×105j/mol, then the equilibrium constant at 2400 k is 2.21×10−3. The answer to the statement is 2.21×10−3.
Answer : The number of oxygen atoms present in glucose are ![24.10\times 10^{23}](https://tex.z-dn.net/?f=24.10%5Ctimes%2010%5E%7B23%7D)
Explanation :
First we have to calculate the moles of glucose.
![\text{moles of glucose}=\frac{\text{Mass of glucose}}{\text{Molar mass of glucose}}](https://tex.z-dn.net/?f=%5Ctext%7Bmoles%20of%20glucose%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20glucose%7D%7D%7B%5Ctext%7BMolar%20mass%20of%20glucose%7D%7D)
Molar mass of glucose = 180 g/mole
![\text{moles of glucose}=\frac{120.0g}{180g/mole}=0.667mole](https://tex.z-dn.net/?f=%5Ctext%7Bmoles%20of%20glucose%7D%3D%5Cfrac%7B120.0g%7D%7B180g%2Fmole%7D%3D0.667mole)
Now we have to calculate the number of oxygen atoms.
The formula of glucose is,
.
In the glucose molecule, there 6 atoms of carbon, 12 atoms of hyrogen and 6 atoms of oxygen.
As, 1 mole of glucose contains
number of oxygen atoms
So, 0.667 mole of glucose contains
number of oxygen atoms
Therefore, the number of oxygen atoms present in glucose are ![24.10\times 10^{23}](https://tex.z-dn.net/?f=24.10%5Ctimes%2010%5E%7B23%7D)
