Write the balanced COMPLETE ionic equation for the reaction when aqueous NiCl₂ and aqueous Na₂S are mixed in solution to form so

Reptile [31]

Answer:

Explanation:

The chemical reaction of the well-balanced equation is as follows:

$\mathbf{2NiCl_{2(aq)}+2Na_2S_{(aq)} \to 4NaCl_{(aq)}+2NiS_{s}}$

The aforementioned reaction's ionic equation is:

$\mathbf{2Ni^{2+}_{(aq)}+4Cl^-_{(aq)}+ 4Na^+_{(aq)}+2S^{2-}_{(aq)} \to 4Na^+_{(aq)}+4Cl^-_{(aq)}+2NiS_{(s)}}$

From above; Na⁺ and Cl⁻ appear on both sides;

Hence, the net ionic equation is:

$\mathbf{2Ni^{2+}_{(aq)}+2S^{2-}_{(aq)} \to 2NiS_{(s)}}$

A chemical reaction is at equilibrium. what will be the effect if more of the product is added? question 10 options: the reactio

VashaNatasha [74]

The answer is the reaction will shift to the left (toward the reactants).

Reaction is at equilibrium can be expressed as,
Reactants ⇄ products

After coming to the equilibrium, if one condition is changed, then according to the Le chatelier's Principal, the system will act to maintain the equilibrium by reducing the effect. As an example, if we reduce the pressure, then system acts to increase the pressure to maintain the equilibrium.

Likewise, if we add products into the reaction which is in equilibrium, the system acts to reduce the effect by promoting the backward reaction to produce reactants.
