B2O3
Explanation:
good luck have a nice day
Answer:
Keq = [NO₂]²/[N₂O₄] = 0.2.
Explanation:
- For the gas mixture equilibrium:
<em>N₂O₄ ⇄ 2NO₂</em>
The expression of the equilibrium constant (Keq):
Keq = [NO₂]²/[N₂O₄]
<em>∴ Keq = [NO₂]²/[N₂O₄]</em> = (0.03)²/(0.0045) = <em>0.2.</em>
Molality can be expressed by moles of solute over
kilograms of solvent. The question asks the molality of 0.25m NaCl. 0.25m NaCl
is equal to 0.25 moles of NaCl over 1 kg of water.
Answer:
The correct answer is option (B) Two molecules of H2 and a molecule of O2 must collide at one time
Explanation:
2H2(g) + O2(g) → 2 H2O(g)
2 1 2
Considering the given reaction, for water molecule to be form, two molecules of hydrogen and one molecule of oxygen must collide at the same time. The product obtained from the collision is two molecules of water as steam. 2 H2O(g)
