The energy of motion predominates in gases, whereas the energy of attraction between particles predominates in solids. In contrast to gases, which lack both defined volume and shape, solids have both.

What do you mean by solid?

One of the three fundamental states of matter, along with liquid and gas. (Ionized gases or plasmas are occasionally regarded as the fourth state of matter.) Because the energy of atoms lowers when they occupy a reasonably organized, three-dimensional structure, a solid develops from a liquid or gas. Solids differ from liquids and gases in that they have certain properties. For instance, all solids can withstand forces that are parallel or perpendicular to a surface (i.e., normal or shear loads, respectively). These characteristics are influenced by the atoms that make up the solid, their arrangement, and the forces that exist between them.

Calculate the pH of a 0.10 M HCN solution that is 0.0070% ionized.
Anastaziya [24]

Answer:

D) 5.15

Explanation:

Step 1: Write the equation for the dissociation of HCN

HCN(aq) ⇄ H⁺(aq) + CN⁻(aq)

Step 2: Calculate [H⁺] at equilibrium

The percent of ionization (α%) is equal to the concentration of one ion at the equilibrium divided by the initial concentration of the acid times 100%.

α% = [H⁺]eq / [HCN]₀ × 100%

[H⁺]eq = α%/100% × [HCN]₀

[H⁺]eq = 0.0070%/100% × 0.10 M

[H⁺]eq = 7.0 × 10⁻⁶ M

Step 3: Calculate the pH

pH = -log [H⁺] = -log 7.0 × 10⁻⁶ = 5.15

How many ug of nickel (Ni) are required to make 25.00 nanoliters of a 1.25 mol/L solution? Be sure to report your answer to the
devlian [24]

volume of Ni = 25 nL = 25 x 10⁻⁹ L

mol Ni = 25 x 10⁻⁹ L x 1.25 mol/L = 3.125 x 10⁻⁸

mass = mol x Ar Ni

mass = 3.125 x 10⁻⁸ x 59 g/mol

mass = 1.84 x 10⁻⁶ g = 1.84 μg
