What best describes the hydrogen atom in a bond such as H-CI?

Electromagnetic waves such as radio waves are used in information transmission either as digital or analogy signals.

Electromagnetic waves are waves which are produced from the interactionof the electric and magnetic fields.

Transmitting data at lower frequencies enables the waves to travel longer distances than at higher frequencies, therefore scientists usually transmit data at a lower frequencies.

The limitations of transmitting information using electromagnetic waves include a limited number of broadcast frequencies and interference of waves.

Analog signals differ from digital signals in that analog signals have continuous electrical signals while digital signals have non-continuous electrical signals.

Digital signals over analog signals is that it transmits more information per second than analog signals Analog and digital signals are employed in mobile devices, television, radio, computers and the internet

A radio telescope is used to receive radio waves from astronomical radio sources in space.

It has several parts such as a dish and antenna,a receiver,a detector and an analyzer. The dish collects and focuses radio signals on the antenna and the information is processed by the receiver, detector and analyzer.

Radios waves are used for the transmission of radio and television signals.

Radio telescopes convert radio waves which are analog signals to electrical signals wgich are digital siagnals because it can be easily stored and transmitted in digital form.

Therefore, electromagnetic waves such as radio waves are used in information transmission.

Taking into account the definition of dilution, 83.3 mL of 0.0833 Lof 12 molar hydrochloric acid would be needed to create 1 L of a 1 molar solution of hydrochloric acid.

When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.

Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:

12 M× Vi= 1 M× 1 L

Solving:

(1 M× 1 L)÷ 12 M= Vi

0.0833 L= 83.3 mL= Vi (being 1 L= 1000 mL)

In summary, 83.3 mL of 0.0833 Lof 12 molar hydrochloric acid would be needed to create 1 L of a 1 molar solution of hydrochloric acid.

Method 1: gravimetry

advantages: Impurities in the sample can be identified

disadvantages: The process is long, because it goes through several stages

Method 2: titration

advantages: the process is fast, because the titrate and titrant react immediately

disadvantages: Sometimes the determination of the end point of the titration is carried out too fast or too slowly so that the calculations carried out are inaccurate

Benzilic acid will only precipitate in acidic solution to remove excess acid and restore equilibrium.

Chemical equilibrium refers to a state in which the rate at which reactant molecules combine to form products is equal to the rate at which products dissociate to form reactants.

For a reaction in equilibrium, any change to distort the equilibrium will cause equilibrium to shift to counter that change.

The components of Benzilic acid exist in equilibrium and will only precipitate in acidic solution because more acid has been added and equilibrium will shift to removal of excess acids.

Therefore, benzilic acid only precipitate in acidic solution in order to remove excess acid and restore equilibrium.

Explanation:

Ca(OH)₂⇒ Ca²⁺ + 2OH⁻

1.3 x 10⁻⁶ = 0.1 . 4s²

s² = 3.25 x 10⁻⁶

s = 1.8 x 10⁻³

1.8 x 10⁻³ is the molar solubility. Solubility is the amount of a substance that can be dissolved in a liquid to form a solution.

Solubility is the amount of a substance that can be dissolved in a liquid to form a solution; it is typically represented as grammes of solute every litre of liquid. One fluid's (liquid or gas) solubility in another can be entire (e.g., methanol and water are completely miscible) or partial (e.g., oil and water barely mix). Generally speaking, "like dissolves like" (for instance, the aromatic hydrocarbons dissolves in one another but not in water).

A material's solubility in two solvents is measured by the distribution coefficient, which is used in some separation techniques (such as absorption and extraction). In general, as temperature rises, so do the dissolution rates of solids in liquids, while they fall as temperature rises and rise with pressure for gases.
