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:
D
Explanation:
Silver is a metal with high conductivity ....
Hope its right !
The correct answer is a solute and a solvent
A solution is any homogenous mixture of two or more substances. It does not necessarily have to be liquid or gaseous.
Trees produce carbon dioxide. They take in carbon monoxide (what we breathe out) and cycle it back for us.
Trees are important!
