33.2 g of iron (Fe)
Explanation:
We have the following chemical reaction in which iron react with oxygen to form the iron (III) oxide:
4 Fe + 3 O₂ → 2 Fe₂O₃
number of moles = volume / 22.4 (L/mole)
number of moles of O₂ = 10 / 22.4
number of moles of O₂ = 0.446 moles
Taking in account the chemical reaction we devise the following reasoning:
if 4 moles of Fe react with 3 moles of O₂
then X moles of Fe react with 0.446 moles of O₂
X = (4 × 0.446) / 3 = 0.595 moles of Fe
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of Fe = 0.595 × 55.8
mass of Fe = 33.2 g

Answer:
Yes oxygen is more reactive than beryllium
Answer: I think the answer is C
Explanation:
Answer:
Mutarotation refers to the change in the optical rotation or optical activity of a solution due to the change in the equilibrium of the two anomers. It depends upon the optical activity and ratio of the anomeric forms in the solution.
To measure the optical rotation of a given solution, a polarimeter can be used and thus the ratio of the anomeric forms can be calculated.
