Chemistry

Reika [66]3 years ago

Answer:

[NaCl] = 1.72 M

Explanation:

First of all, we balance the equation:

BaCl₂ + Na₂SO₄ →  2NaCl + BaSO₄

We convert mass of barium chloride to moles

45 g . 1mol / 208.23g = 0.216 moles

Ratio is 1:2. This means, that our moles of reactant may produce the double of moles, of product.

0.216 . 2 = 0.432 moles of NaCl are been produced.

Molarity is mol/L. We convert volume of water from mL to L

250 mL . 1L /1000 mL = 0.250 L

[NaCl] = 0.432 mol/0.250L = 1.72 M

How does a system at equilibrium respond to the addition of more reactant
grin007 [14]

Answer:

It favors the forward reaction.

Explanation:

According to Le Chatelier's Principle, when a system at equilibrium suffers a perturbation, the system will react in order to counteract the effect of such perturbation.

If more reactant is added, the system will try to decrease its concentration. It will do so by favoring the forward reaction, decreasing the concentration of the reactant  and increasing the concentration of the products, in order to re-establish the equilibrium.
