Answer:
![n_{Mg}=3.50molMg\\\\ n_{Cl}=7.00molCl\\\\n_O=28.0molO](https://tex.z-dn.net/?f=n_%7BMg%7D%3D3.50molMg%5C%5C%5C%5C%20n_%7BCl%7D%3D7.00molCl%5C%5C%5C%5Cn_O%3D28.0molO)
Explanation:
Hello there!
In this case, according to the given information it turns out possible for us to realize that one mole of the given compound, Mg(ClO₄)₂, has one mole of Mg, two moles of Cl and eight moles of O; thus, we proceed as follows:
![n_{Mg}=3.50molMg(ClO_4)_2*\frac{1molMg}{1molMg(ClO_4)_2}=3.50molMg\\\\ n_{Cl}=3.50molMg(ClO_4)_2*\frac{2molCl}{1molMg(ClO_4)_2}=7.00molCl\\\\n_O=3.50molMg(ClO_4)_2*\frac{8molO}{1molMg(ClO_4)_2}=28.0molO](https://tex.z-dn.net/?f=n_%7BMg%7D%3D3.50molMg%28ClO_4%29_2%2A%5Cfrac%7B1molMg%7D%7B1molMg%28ClO_4%29_2%7D%3D3.50molMg%5C%5C%5C%5C%20n_%7BCl%7D%3D3.50molMg%28ClO_4%29_2%2A%5Cfrac%7B2molCl%7D%7B1molMg%28ClO_4%29_2%7D%3D7.00molCl%5C%5C%5C%5Cn_O%3D3.50molMg%28ClO_4%29_2%2A%5Cfrac%7B8molO%7D%7B1molMg%28ClO_4%29_2%7D%3D28.0molO)

Answer:
a. 342.9 kJ of heat are absorbed.
Explanation:
Calculation of the moles of
as:-
Mass = 20.00 g
Molar mass of
= 17.031 g/mol
The formula for the calculation of moles is shown below:
Thus,
![Moles= 1.1743\ mol](https://tex.z-dn.net/?f=Moles%3D%201.1743%5C%20mol)
Given that:- ![\Delta H=+1168\ kJ](https://tex.z-dn.net/?f=%5CDelta%20H%3D%2B1168%5C%20kJ)
It means that 1 mole of
undergoes reaction and absorbs 1168\ kJ of heat
So,
1168 mole of
undergoes reaction and absorbs
of heat
<u>Amount of heat absorbed = + 342.9 KJ</u>
