Hydrogen chloride or most commonly known as hydrochloric acid and
muriatic acid is a diatomic compound that consists of hydrogen and chlorine. It
is prepared industrially by the combustion of hydrogen, H2, in chlorine, Cl2.
H2 + Cl2 -> 2HCl. There are also many metallic chlorides that release
hydrogen chloride gas, HCl, when warmed with concentrated sulfuric acid, H2SO4.
Mostly, it is prepared by heating it with sulfuric acid and sodium chloride.
The reaction is NaCl + H2SO4 -> HCl + NaHSO4. Adding sulfuric acid enables the reaction to proceed further and it acts as a catalyst in the reaction.
The solution for this problem is:
The information given lacks but nevertheless the answer is:
So, the total heat free by dissolving the solute was 1386 + 32 = 1417 J
Then, dissolving of the solute will have released -1417 J. So, per gram of Al2
(SO4)3 dissolved:
-1417 J / 25 g = -56.7 J/g
Translating that to a per mole: -56.7 J/g X 342 g/mol = -1.94X10^4 J/mol = -19
kJ/mol = this would be Delta Hsoln
Answer:
<h2>4.03 × 10²³ atoms</h2>
Explanation:
The number of S atoms can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 0.67 × 6.02 × 10²³
We have the final answer as
<h3>4.03 × 10²³ atoms</h3>
