Answer:
Oxygen is in excess.
Explanation:
The coefficients of the balanced equation create a mole ratio that shows the ratio of how many reactants are used up and products are created.
The mole ratio of Mg to O2 in this equation is 2:1, which means that for every two moles of Mg used, there will be 1 mole of O2 used.
If we have 3.00 moles of Mg, we will only need 1.5 moles of oxygen to completely burn the Mg. Therefore, when all 3.00 moles of Mg are used, there will still be some of the 2.20 moles of oxygen remaining.
I am not sure about my answer, but I think that it's density allows it to fall to the ground/floor.

Answer: It takes 5.89 s for the concentration of 
to decrease by 88.0%.
Explanation:
As the units of rate constant is 
, the kinetics must be second order.
Integrated rate law for second order kinetics is given by:
= initiaal concentration = 0.590 M
a= concentration left after time t = 
Thus it takes 5.89 seconds for the concentration of to decrease by 88.0%.
