Explanation:
Reaction equation is as follows.
Here, 1 mole of 
produces 2 moles of cations.
![[Na^{+}] = 2[Na_{2}SO_{3}] = 2 \times 0.58](https://tex.z-dn.net/?f=%5BNa%5E%7B%2B%7D%5D%20%3D%202%5BNa_%7B2%7DSO_%7B3%7D%5D%20%3D%202%20%5Ctimes%200.58)
= 1.16 M
![[SO^{2-}_{3}] = [Na_{2}SO_{3}]](https://tex.z-dn.net/?f=%5BSO%5E%7B2-%7D_%7B3%7D%5D%20%3D%20%5BNa_%7B2%7DSO_%7B3%7D%5D)
= 0.58 M
The sulphite anion will act as a base and react with 
to form 
and 
.
As,

= 
According to the ICE table for the given reaction,
Initial: 0.58 0 0
Change: -x +x +x
Equilibrium: 0.58 - x x x
So,
![K_{b} = \frac{[HSO^{-}_{3}][OH^{-}]}{[SO^{2-}_{3}]}](https://tex.z-dn.net/?f=K_%7Bb%7D%20%3D%20%5Cfrac%7B%5BHSO%5E%7B-%7D_%7B3%7D%5D%5BOH%5E%7B-%7D%5D%7D%7B%5BSO%5E%7B2-%7D_%7B3%7D%5D%7D)
x = 0.0003 M
So, x = ![[HSO^{-}_{3}] = [OH^{-}]](https://tex.z-dn.net/?f=%5BHSO%5E%7B-%7D_%7B3%7D%5D%20%3D%20%5BOH%5E%7B-%7D%5D)
= 0.0003 M
![[SO^{2-}_{3}]](https://tex.z-dn.net/?f=%5BSO%5E%7B2-%7D_%7B3%7D%5D)
= 0.58 - 0.0003
= 0.579 M
Now, we will use ![[HSO^{-}_{3}]](https://tex.z-dn.net/?f=%5BHSO%5E%7B-%7D_%7B3%7D%5D)
= 0.0003 M
The reaction will be as follows.
Initial: 0.0003
Equilibrium: 0.0003 - x x x
= 
= 
Therefore, 
As, x <<<< 0.0003. So, we can neglect x.
Therefore, 
= 
x = 
x = ![[OH^{-}] = [H_{2}SO_{3}]](https://tex.z-dn.net/?f=%5BOH%5E%7B-%7D%5D%20%3D%20%5BH_%7B2%7DSO_%7B3%7D%5D)
= 
![[H^{+}] = \frac{10^{-14}}{[OH^{-}]}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%20%3D%20%5Cfrac%7B10%5E%7B-14%7D%7D%7B%5BOH%5E%7B-%7D%5D%7D)
= 
= 
M
Thus, we can conclude that the concentration of spectator ion is M.
Answer:
Nutrition has a significant impact on numerous reproductive functions including hormone production, folliculogenesis, fertilization, and early embryonic development
Explanation:
This intimate association is because reproductive processes are energetically expensive, and the brain must temper the fertility of individuals to match nutritional availability.Reproduction function in mammals can be inhibited when food availability is low or when increased energy demands are not met by compensatory food intake such as in short-term and chronic withdrawal of nutrients.This very close alignment with the food supply is more important in females, where pregnancy and lactation are linked to considerable energetic expenses, needed for the nurture of embryos and newborns. In fact, her reproductive outcome can be seriously altered and even life threatening to both the mother and offspring when nutritional imbalance occurs. In order to keep constant body energy stores, in mammals, a series of homeostatic events leading to maintenance of energy balance are activate when a state of energy scarcity or abundance occurs.

Answer:
All atoms of the same element have always have the same amount of protons.
Explanation:
Atoms of the same element have always have the same amount of protons but not always the same electrons and neutrons. If an atom gains or loses one of its valance electrons, the electrons on the outermost shell, then it becomes ionized. Also not all atoms of the same element have the same amount of neutron. This is called an isotope. A good example would be Carbon 13. Normally, Carbon atoms have an atomic mass of 12 AMU or 12 atomic mass units. However, Carbon atoms have an atomic mass of 13 AMU, consisting of 7 neutrons instead of 6 neutrons. So the only thing that all atoms of the same element have in common is the amount of protons.
