Answer:
the ice age is I think 8 then happened to the massive amount of plant is 10 and thice time is ice fully glow because it is cold.
The reaction equation:
2H₂O + 2Na₂O₂ → 4NaOH + O₂
Moles of sodium peroxide = 10 / 78 = 0.128
Moles of oxygen released = 0.128 / 2 = 0.064 mol
Mass of oxygen = 0.064 x 32
Mass of oxygen = 2.05 grams
