What is emission spectrum and absorption spectrum? ​

Chemistry

- emission spectrum is the amount of electromagnetic radiation of each frequency it emits when it is heated (or more generally when it is excited). When the electrons in the element are excited, they jump to higher energy levels.



- Absorption spectrum is a technique used to find out what makes up a sample of a substance – in other words, a chemical analysis.

Answer:

When matter interact with EMR then spectrum is obtained. We can understand both spectra using Bohr's hydrogen spectrum. let's have a look on Bohr's hydrogen spectrum what does it say. It says when a electron gains energy it moves from one energy level to other(lower to higher) which is Absorption phenomenon. When the electrons returns from excited state to ground state they emits several spectral lines. this spectrum is called as emission spectrum. inshort the

<em>E</em><em>mission spectrum is spectrum of electromagnetic radiations that were emitted from the higher energy state(Excited state) to lower energy state(Ground state)</em><em>.</em><em> </em><em>and </em><em>study </em><em>o</em><em>f </em><em>emission</em><em> </em><em>spectrum </em><em>is </em><em>known </em><em>as </em><em>AES </em><em>(</em><em>Atomic </em><em>Emission</em><em> </em><em>spectroscopy</em><em>)</em><em>.</em>

<em>When an atom or ion is subjected to EMR, it absorbs certain level of radiations, and when this absorbed energies are studied under spectroscopy they are plotted as absorption </em><em>spectrum</em><em>,</em><em> </em><em>and </em><em>study </em><em>of </em><em>Absorption </em><em>spectrum </em><em>is </em><em>known </em><em>as </em><em>AAS</em><em> </em><em>(</em><em>Atomic</em><em> </em><em>Absorption</em><em> </em><em>spectroscopy</em><em>)</em><em>.</em>

What is the solubility of a solid in a solvent?
patriot [66]

Answer:

Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. ... The solvent is often a solid, which can be a pure substance or a mixture.

How many moles of water are in a beaker with 50 mL?
tatiyna

Answer:

Number of moles = 2.8 mol

Explanation:

Given data:

Number of moles of water = ?

Volume of water = 50 mL

Density of water = 1.00 g/cm³

Solution:

1 cm³ =  1 mL

Density = mass/ volume

1.00 g/mL = mass/ 50 mL

Mass = 1.00 g/mL× 50 mL

Mass = 50 g

Number of moles of water:

Number of moles = mass/molar mass

Number of moles = 50 g / 18 g/mol

Number of moles = 2.8 mol
