Earth's Spheres. Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

<span>the lithosphere, which contains all of the cold, hard, solid rock of the planet's crust (surface), the hot semi-solid rock that lies underneath the crust, the hot liquid rock near the center of the planet, and the solid iron core (center) of the planet </span>the hydrosphere, which contains all of the planet's solid, liquid, and gaseous water,and the atmosphere, which contains all of the planet's air

What is the ph of a buffer that is 0. 08 m naa and 0. 1 ha. The ka of ha = 1. 0 x 10^-4
Crank

Henderson-Hasselbalch equation relates the pH with the dissociation constant of the acid. The pH of the buffer solution will be 3.90.

<h3>What is the Henderson-Hasselbalch equation?</h3>

The Henderson-Hasselbalch equation is used to calculate the pH or the concentration of the conjugate base and acid.

The Henderson-Hasselbalch equation can be given as,

pH = pKa + log [A⁻] ÷ [HA]

The dissociation reaction is given as,

HA⁺ + H2O ⇌ H3O⁺ + A⁻

NaA → Na⁺ + A⁻

For this first pKa is calculated as:

pKa = - log (1. 0 x 10⁻⁴)

Substituting the value of pKa in Henderson-Hasselbalch equation pH is determined as:

pH = - log (1. 0 x 10⁻⁴) + log [0.08] ÷ [0.1]

= 4 + (-0.0969)

= 3.90

Therefore, 3.90 is the pH of the solution.

Which ionic equation for reaction of Magnesium with dilute hydrochloric acid is correct? Mg (s) + 2H+ (aq) â Mg2+ (aq) + H2 (g)
belka [17]

Answer:

Mg(s) + 2H⁺(aq) ⟶ Mg²⁺(aq) + H₂(g)  

Explanation:

A net ionic equation shows all the ionic substances as ions and shows the correct state of each substance.

B. is wrong. HCl ionizes in aqueous solution into H⁺ and Cl⁻.

C. is wrong. Mg²⁺ is not a solid. It is an aqueous ion.

D. is wrong. The equation needs 2H⁺(aq) to be balanced.
