Answer : The number of moles of ions form are,
and there are 3 ions formed.
Explanation :
First we have to calculate the moles of calcium iodide.
![\text{Moles of }CaI_2=\frac{\text{ given mass of }CaI_2}{\text{ molar mass of }CaI_2}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DCaI_2%3D%5Cfrac%7B%5Ctext%7B%20given%20mass%20of%20%7DCaI_2%7D%7B%5Ctext%7B%20molar%20mass%20of%20%7DCaI_2%7D)
Molar mass of calcium iodide = 293.9 g/mol
Mass of calcium iodide = 51.0 g
Now we have to calculate the number of moles of ions.
As we know that when calcium iodide dissolved in water then it dissocites to give calcium ion and iodide ion.
The balanced chemical reaction will be:
![CaI_2(aq)\rightarrow Ca^{2+}(aq)+2I^{-}(aq)](https://tex.z-dn.net/?f=CaI_2%28aq%29%5Crightarrow%20Ca%5E%7B2%2B%7D%28aq%29%2B2I%5E%7B-%7D%28aq%29)
From this we conclude that there are 3 ions formed.
As, 1 mole of calcium iodide dissociate to give
number of ions
So, 0.174 mole of calcium iodide dissociate to give
number of ions
Thus, the number of moles of ions form are, ![3.14\times 10^{23}](https://tex.z-dn.net/?f=3.14%5Ctimes%2010%5E%7B23%7D)
The biotic factors are bacteria soil, dead leaves, and stream water.
<h3>What is an abiotic factor?</h3>
An abiotic factor is a non-living part of an ecosystem that shapes its environment.
Biotic and abiotic factors make up a community via interaction.
Biotic factors are considered living things (having "life") while abiotic factors are simply non-living things.
The dead leaves of plants are an abiotic factor, the bacteria in soil are living matter and stream flowing, etc.
Hence, the biotic factors are bacteria soil, dead leaves, and stream water.
