Answer:
0.404 moles Na⁺ and 0.404 moles Cl⁻
Explanation:
In the solution you have 23.6g of NaCl. As molar mass of NaCl is 58.44g/mol. Moles you have present are:
23.6g NaCl × (1mol / 58.44g) = <em>0.404 moles of NaCl</em>
As you can see in the formula, each mole of NaCl contains 1 mole of Na⁺ and 1 mole of Cl⁻. Thus, moles of each ion are:
<em>0.404 moles Na⁺ and 0.404 moles Cl⁻</em>
2Al + 6H₂O ⇒ 2Al(OH)₃ + 3H₂
2mol : 2V
54g : 67,2L
268,5g : Vₓ
vₓ = 67,2dm³*268,5g / 54g ≈ 334,13L

Answer:
a) Equilibrium shifts in forward direction.
Explanation:
If pressure is increased, equilibrium shifts to the side with the fewer moles of gas.
There are 4 moles of gas in the reactants and 2 moles of gas in the products.
The equilibrium will shift in the forward direction towards the products.
Hope that helps.
