6.7 mass because 1 atom equals 6.3 but if u add 4 it would be 6.7
Chemical Bonding, my dude.
Explanation:
Energy must be added to change carbon powder into synthetic diamond because at ordinary temperature and pressure conditions, this reaction will not take place.
To form diamond, conditions of high pressure must be made available. Diamond is an allotrope of carbon that is very hard and difficult to break.
To form diamond synthetically, we must be able to replicate the natural conditions by which it forms.
Diamond forms under very high grade metamorphic pressure. This must also be the condition to form the synthetic variant.

Answer:
3 moles of CO are needed
Explanation:
Given data:
Number of moles of CO used = ?
Mass of Fe produced = 112 g
Solution:
Chemical equation:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Number of moles of Fe:
Number of moles = mass/ molar mass
Number of moles = 112 g/ 55.85 g/mol
Number of moles = 2.00 mol
Now we will compare the moles of iron and CO.
Fe : CO
2 : 3
Thus, 3 moles of CO are needed.
