Answer: H_2SO_4(aq)

Explanation:

An acid is defined as the acid which completely dissociates when dissolved in water and release H^+ ions in their aqueous states.

A base is defined as the base which completely dissociates when dissolved in water and releases OH^- ions in their aqueous states.

Mg is an element, H_2 is a compound, MgSO_4 is a salt formed by combination of acid and base.

The equation for the dissociation of sulphuric acid is given by:

H_2SO_4(aq.)\rightarrow 2H^+(aq.)+SO_4^{2-}(aq.)

Answer:

H2SO4

Explanation:

H2SO4 is actually one of the strongest acids, coming to a pH value very close to 1. Acids transfer their hydrogen ions to other substances, such as water, and usually have hydrogen in their formula. In this case, H2SO4 has hydrogen in its formula and is the acid in this case.

(01.07 но) An experiment was conducted to determine the density of a liquid. The table shows a partial record of the experiment
Anestetic [448]

Answer:

How do you find the density of a liquid experiment?

To measure the density of a liquid you do the same thing you would for a solid. Mass the fluid, find its volume, and divide mass by volume. To mass the fluid, weigh it in a container, pour it out, weigh the empty container, and subtract the mass of the empty container from the full container.

g For the reaction Ag2S(s)⇌2Ag+(aq)+S2−(aq)Ag2S(s)⇌2Ag+(aq)+S2−(aq), Keq=2.4×10−4Keq=2.4×10−4, and the equilibrium concentration
Roman55 [17]

Answer:

0.32 M

Explanation:

Step 1: Write the balanced reaction at equilibrium

Ag₂S(s) ⇌ 2 Ag⁺(aq) + S²⁻(aq)

Step 2: Calculate the concentration of Ag⁺ at equilibrium

We will use the formula for the concentration equilibrium constant (Keq), which is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It only includes gases and aqueous species.

Keq = [Ag⁺]² × [S²⁻]

[Ag⁺] = √{Keq / [S²⁻]}

[Ag⁺] = √{2.4 × 10⁻⁴ / 0.0023} = 0.32 M
