Two samples of mg(s) of equal mass were placed in equal amounts of hcl(aq) contained in two separate reaction vessels. particle representations of mixing of mg(s) and hcl(aq) in the two reaction vessels are shown in figure 1 and 2 above. water molecules are not included in the particle representations. which of the reactions will initially proceed faster and why?

Explanation:

The two figures are missing so I can't tell which reactions will proceed faster, but the answer will follow this logic:

If the two samples of Mg(s) are equal, the two amounts of HCl(aq) are equal, the operation conditions are the same (Temperature, pressure,etc.), the difference in the speed of reaction will only depend difference in the quality of mixing of the Mg(s).

Being that said:

heat or electricity in the atmosphere- c.
