You could identify a physical property of a substance before you performed the activity because the characteristics of a material known as its physical qualities are those that may be investigated independently of the substance's chemical makeup.
This is further explained below.

Answer:
endoplasmic reticulum (ER)
Answer:
Mass of Fe produced = 4.468 g
Explanation:
Given data:
Mass of Fe produced = ?
Mass of Fe₂O₃ react = 6.50 g
Solution:
Chemical equation:
2Fe₂O₃ → 4Fe + 3O₂
Number of moles of Fe₂O₃ ;
Number of moles = mass/molar mass
Number of moles = 6.50 g/159.69 g/mol
Number of moles = 0.04 mol
Now we will compare the moles of iron and ironoxide.
Fe₂O₃ : Fe
2 : 4
0.04 : 4/2×0.04 = 0.08 mol
Mass of iron produced:
Mass = number of moles × molar mass
Mass = 0.08 mol × 55.85 g/mol
Mass = 4.468 g
