Question

Magnesium reacts with acids to produce hydrogen gas. Under which set of conditions is hydrogen formed the most slowly? A, B, C, or D?

Answer 1

Answer:

I think option B !

Explanation:

Because is hydrogen is to be formed slowly then it should be reacted with a dilute acid ! And hydrogen is a fire catching gas so the temperature should also be pretty low !

Answer 2

Answer:

Option B

Explanation:

It is because in option B , the magnesium ribbon is reacting with dilute acid , the magnesium ribbon has less surface to react with acid as compared to the magnesium powder and the dilute acid reacts slowly than the concentrated one . so, option b will have the least ideal conditions as compared to the other three options .
