Answer:
the answer is k? lol thanks
The first option is the correct.
Since we know the mass of one atom of Fe is 56 and that of Cl2 atoms is 71 (one atom has 35.5 mass) hence both of them will be consumed
I am sorry I don't know, points are points though

Answer: -
A catalyst is a substance that speeds up the chemical reaction. In the first experiment it took 32 minutes for all the magnesium to react.
In the next it took 54 minutes for all the magnesium to react. So the reaction was slower the second time.
Thus a catalyst was not used.
Powdering up the Magnesium would mean increasing the surface area. More the surface area faster the reaction. Since the reaction is slowing down,
Magnesium was not powdered
If the temperature was decreased then kinetic energy would decrease of the reactant molecules and the reaction would slow down due to less number of collisions between reactant moleules.
So the temperature was decreased is a correct option.
