Answer:
4.13 moles of Fe.
Explanation:
Given data:
Moles of iron produced = ?
Moles of Fe₂O₃ = 3.5 mol
Moles of CO = 6.2 mol
Solution:
Chemical equation:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Now we will compare the moles of iron with CO and Fe₂O₃.
Fe₂O₃ : Fe
1 : 2
3.5 : 2/1×3.5 = 7 mol
CO : Fe
3 : 2
6.2 : 2/3×6.2 = 4.13 mol
The number of moles of iron produced by CO are less it will limiting reactant.
Thus, moles of iron formed in given reaction are 4.13 moles.

Explanation:
thermal changes are those in which heat exchange is involved like endothermic and exothermic
while in chemical changes collision between the reactant occurs which result into product
Answer:
it is in the same phase as the reactants
Answer:
12
Explanation:
6 moles multiplied 2 atoms of O2
That gives 12 atoms
