The answer is ( 2.6 mol HCl )
1) It stands for sulfur
2) 16
3)It stands for the number of protons
4)Chalcogen
Explanation:
I'm pretty sure the answer is D
The reaction is a hydrogenation reaction of an alkene, and its equation is:
C₂H₄(g) + H₂(g) → C₂H₆(g)
Therefore, this reaction can be sped up just as any other irreversible reaction may have its rate increased, by increasing temperature and pressure to increase the effective collisions of molecules.
