<h3>Answer:</h3>

0.162 M

<h3>Explanation:</h3>

We are given;

  • Initial concentration as 18.0 M
  • Initial volume of the solution is 18.0 mL or 0.018 L
  • Final volume of the solution is 2.0 L

We are required to find the final concentration or molarity.

  • When a solution is diluted by adding more solvent, the concentration of the solution decreases.
  • To find the final concentration of the dilute solution we use the dilution formula, C1V1 = C2V2.

Rearranging the formula;

C2 = C1V1 ÷ V2

     = (18 M × 0.018 L) ÷ 2.0 L

     = 0.162 M

Therefore, the final concentration will be 0.162 M

what conclusions can be made about the relationship between metallic character and the atomic radius?
kolezko [41]

We have to get the relationship between metallic character and atomic radius.

Metallic character increases with increase in atomic radius and decrease with decrease of atomic radius.

If electrons from outermost shell of an element can be removed easily, that atom can be considered to have more metallic character.

With increase in atomic radius, nuclear force of attraction towards outermost shell electron decreases which facilitates the release of electron.

With decrease in atomic radius, nuclear force of attraction towards outermost shell electrons increases, so electrons are hold tightly to nucleus. Hence, removal of electron from outermost shell becomes difficult making the atom less metallic in nature.

An air sample consists of oxygen and nitrogen gas as major components. It also contains carbon dioxide and traces of some rare g
jekas [21]

Explanation:

A mixture is defined as the substance that contains two or more different number of substances that are physically mixed together.

For example, a mixture of air which contains oxygen, nitrogen and other gases.

A mixture in which solute particles are unevenly distributed into the solvent then it is known as a heterogeneous mixture.

For example, sand in water is a heterogeneous mixture.

A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed in a solvent.

A homogeneous mixture is a clear solution.

For example, salt dissolved in water is a homogeneous mixture.

A solution is defined as the substance in which two or more substances are mixed together.

A compound is defined as the substance that contains two or more different elements that chemically combined together in a fixed ratio by mass.

A element is defined as the substance that contains only one type of atoms.

For example, a piece of sodium element will contain only atoms of sodium.

Whereas a pure substance is defined as the substance which contains only one type of molecule or one type of atom.

For example, O_{2}, N_{2} etc are pure substances.

Thus, we can conclude that the terms which could be used to describe the given sample of air is as follows.

  • pure chemical substance.
  • heterogenous mixture.
  • mixture.

What is the working of NMR?
tiny-mole [99]

Answer:

NMR stands for Nuclear Magnetic Resonance, and NMR spectroscopy is the technology that makes use of the phenomena of NMR in the analysis of a material's molecular structure through measurement and observance of the nuclear spin interactions, in order to determine the biological, physical and chemical properties of the material

NMR works by the noting that some atoms in molecules placed in a strong magnetic field display the characteristics of small magnets. The application of a broad spectrum radio frequency to the molecules will cause the nuclei to resonate at particular frequencies. An NMR spectrum is formed from the measured nuclei resonant frequencies such that the graph peaks shows the correct frequencies in the sample and the peak height is directly related to the proportion or number of the nuclei which are resonating to a given frequency, such that the frequency values are indicative of the type of atoms and their distances apart from a given atom

Rank these photons in terms of increasing energy:<br> (b) red (λ = 660 nm);
Rama09 [41]

The order of increasing energy is red, yellow, and blue

In physics for a given wave function, the wavelength is defined as the distance between two consecutive points in the waveform. Light is considered a wave and a particle. White light can split into colors of different wavelengths.

The wavelength of visible light ranges from 300 to 700 nm comprising the color VIBGYOR. Wavelength is calculated by the formula velocity divided by the frequency.

If the frequency of the given form is high, then the energy is also high.

brainly.com/question/10750459

#SPJ4

Rank the following photons in terms of increasing energy: (a) blue (λ = 453 nm); (b) red (λ = 660 nm); (c) yellow (λ = 595 nm).

As the frequency is inversely proportional to the wavelength, the energy is also inversely proportional. A higher wavelength will have lower energy.
