The best statement which describes a reaction in a state of equilibrium is letter D.  <span>The rate of the forward reaction equals the rate of the reverse reaction and the </span>concentrations of products and reactants are constant. 

>Chemical equilibrium<span> is defined as<span> the state in which both reactants and products are present in </span></span>concentrations<span> which have no further tendency to change with time. This state results when the forward reaction proceeds at the same rate as the </span>reverse reaction<span>. The </span>reaction rates<span> of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s).</span>

<span> </span>

Which of the following is a basic solution? HCl dissolved in water b. household ammonia c. vinegar d. pure water
PSYCHO15rus [73]

Answer:

B. Household ammonia.

Explanation:

NH₃ is a base, so the solution always will be basic.

NH₃ takes the proton from the water. In conclusion we have free OH⁻ in medium, that's why the solution is basic.

NH₃ + H₂O → NH₄⁺  +  OH⁻

- HCl + H₂O → H₃O⁺  + Cl⁻

This reaction makes an acid solution, cause the H₃O⁺

- Vinegar is a compound made of acetic acid.

CH₃COOH  + H₂O  ⇄  H₃O⁺  +  CH₃COO⁻

This reaction also makes an acid solution, cause the H₃O⁺

- Pure water makes neutral solution. It is not acid, neither basic.

2H₂O ⇄  H₃O⁺  +  OH⁻
