Fe2O3 + 3C → 2Fe + 3CO :)
Answer:
BC = 10.28 ≈ 10.3 mi to the nearest tenth
Explanation:
Using the trigonometry rules; SOH CAH TOA,
TOA would be more suitable in this question.
Tan ∅ = Opposite / Adjacent
Tan 61 = BC / AB
1.8040 = BC / 5.7
BC = 5.7 * 1.8040
BC = 10.28 ≈ 10.3 mi
The electron orbits the nucleus so your answer would be C.

Answer:
18 molecules of oxygen or o2
Explanation:
Because a carbon dioxide molecule has 2 oxygen molecules and 1 carbon molecule, this would mean that, to make 9 co2 molecules, you would need
18 because 9x2 is 18 molecules of 02
and for carbon molecules its literally 9 because for just 1
co2 it contains 1 carbon molecule
hope this helped
