The mass of oxygen gas is released in the reaction of decomposition of magnesium oxide 6.4 grams
calculation
mass of oxygen=mass of magnesium oxide -mass of magnesium produced
that is 16.12-9.72=6.4 grams
The answer here is B: Max Planck
Answer:
A
Explanation:
It is correct please I hope it helps! :)
The metal increases the rate of reaction by providing an alternative pathway with a lower activation energy. this means that more reactant molecules will have energy equal to or greater than the activation energy, hence higher rate of reaction.
