There are four sublevels s, p, d ,f 2 in the s
Answer is: 0.0213M.
Reaction: N₂O₄ (g) ↔ 2NO₂ (g).
Kc = 0,211 at <span>100°C.
Kc - </span><span>equilibrium constant.
</span>c (N₂O₄) = [N₂O₄] = 0,00251M.
c (NO₂) = [NO₂] = ?
Kc = [NO₂]² / [N₂O₄]
[NO₂]² = Kc · [N₂O₄]
[NO₂] = √(Kc · [N₂O₄<span>]) </span>
[NO₂] = √(0.211 · <span>0.00215M) </span>
[NO₂] = 0.0213M.
Answer:
220mL

Answer:
The embryo, endosperm, and seed coat are the three major parts of a seed. An embryo is the young multicellular organism formed before it emerges from the seed. A seed is an embryonic plant, which stores food and is enclosed in a protective outer covering, which give rise to a new plant.
