Answer:
Kc = 0.20
Explanation:
N₂O₄ ⇄ 2NO₂
moles 5.3mol 2.3mol
Vol 5L 5L
Molarity 5.3/5M 2.3/5M
= 1.06M = 0.46M
Kc = [NO₂]²/[N₂O₄] = (0.46)²/(1.06) = 0.1996 ≅ 0.20
It would form into NaCl because Na has a +1 charge while Cl has a -1 charge.
A- Change the phase of the matter
Oxygen in oxides has oxidation number -2.
<span>Al⁺³₂O⁻²₃
+3*2 -2*3=0</span>
when hydrochloric acid is added to a potassium hydroxide solution, the acid and base would react to form salt(potassium chloride) and water
Chemical Formula:
HCl(aq) +KOH(aq) ---> KCl (aq) + H20 (l)
