The balanced chemical equation is :

Moles of
,

Now, by given chemical equation , we can see 2 mole of
react with 1 mole of
.
So , 2.27 mole react with :

Mass of oxygen is :

Therefore, mass of oxygen in grams produced is 18.16 g.
Hence, this is the required solution.
Answer:
Cells are the basic structural unit of all living organisms.
Explanation:
Hope this helps, but i'm unsure if it would be multiple choice or not.
Answer:
i think kinetic energy sorry if I'm wrong.
Answer:
18.0 Ampere is the size of electric current that must flow.
Explanation:
Moles of electron , n = 550 mmol = 0.550 mol
1 mmol = 0.001 mol
Number of electrons = N

Charge on N electrons : Q

Duration of time charge allowed to pass = T = 49.0 min = 49.0 × 60 seconds
1 min = 60 seconds
Size of current : I



18.0 Ampere is the size of electric current that must flow.
Propylethylene would be the answer
