The answer to that question would be C
If it's an endothermic reaction, then that means heat is being added to the system therefore H>0. Entropy is disorder, and since there are more moles on the products side, entropy is increasing therefore S>0 as well.
Answer:

Explanation:
hope this helps :) also if u can pls mark me as brainliest it would be a great help
Answer:
The metalloids are in a group of elements in the periodic table we know for the kinds of atom types.
Explanation:
Hope this helps u.. :D
2Al(s) + 3Cl₂ → 2AlCl₃
Forming the equation:
2(28) + 3(223) = ΔH + 2(111)
ΔH = 503 kJ
Writing this outside of the reaction equation:
ΔH = -503 kJ
