The Balmer series consists of the spectral lines from hydrogen for an electron making a transition from an excited state to the

m = 2 state. The Lyman series consists of the spectral lines from hydrogen for an electron making a transition from an excited state to the m = 1 state. Determine the wavelengths of the first four spectral lines of the Lyman series (n = 2, 3, 4, and 5)

Answer:

Wavelength of the first four spectral line:

\lambda_1=1216{\AA}

\lambda_2=1026{\AA}

\lambda_3=972.8{\AA}

\lambda_4=950{\AA}

Explanation:

Lman series when electron from higher shell number and jumps to 1st shell then all the possible lines is called as lyman series.

to calculate wavelength of first four spectral line:

For hydrogen Z=1;

by using rydberg equation

\frac{1}{\lambda} =RZ^2[\frac{1}{n_1^2} -\frac{1}{n_2^2} ]

1. n=2 to n=1

\frac{1}{\lambda} =RZ^2[\frac{1}{n_1^2} -\frac{1}{n_2^2} ]

\frac{1}{R} =912{\AA} =rydberg constant

\lambda=\frac{4}{3R}

\lambda_1=1216{\AA}

2. n=3 to n=1

\lambda=\frac{9}{8R}

\lambda_2=1026{\AA}

3. n=4 to n=1

\lambda=\frac{16}{15R}

\lambda_3=972.8{\AA}

4. n=5 to n=1

\lambda=\frac{25}{24R}

\lambda_4=950{\AA}

Why is studying light and electrons important for chemistry and understanding the universe?
Brut [27]

Explanation :

The study of light and electrons are important for chemistry & universe.

   As we know, everything is made up of particles even light & universe also. The particles are made of atoms and that atoms are made up of electrons, protons & neutrons.

   An electron is one of the most important type of subatomic particles. Electrons combine with the proton to form atom. These electrons, protons & neutrons play a vital role in chemistry and universe.

   The importance of an electron is that when two atoms react with each other or approach each other, their outermost shells come into contact first and these outermost shells electrons are involved in the chemical reaction.

    Also important for chemical reactions, creating bonds, for electricity and the understanding of electrons has allowed for the better understanding of some forces which are in our universe such as electromagnetic force.

    We know that the light is act as particle nature and it is a part of universe. As we know that chemists are only responsible for the chemical's study. Chemists cannot study the whole universe that is why they study light and the light is important because nothing would be able to survive.

    The studying of light is important for the photoelectric effect, absorption, bio-molecules synthesis, vitamin D synthesis, vision, colors, drying & evaporation, sterilization, solar energy, spectroscopy, signal system and also for electron excitation.

Which organelle of a prokaryotic cell contains genetic information?
vodomira [7]

Answer:

The right option is the 4 one. nucleoid

Prokaryotic cells are simple cells that lack a definite nucleus and some membrane-bound organelles. Prokaryotic cells have a nucleoid region, which is an irregularly-shaped central region of the cell that contains the cell’s genetic information (DNA). Other organelles that can be found in prokaryotic cells include plasma membrane, cell wall, cytoplasm, and ribosomes.

What is the freezing point (in degrees Celcius) of 4.14 kg of water if it contains 235.1 g of butanol, C 4 H 9 O H
Karolina [17]

Answer:

Explanation:

Molal freezing point depression constant of butanol Kf = 8.37⁰C /m

ΔTf = Kf x m , m is no of moles of solute per kg of solvent .

mol weight of butanol = 70 g

235.1 g of butanol = 235.1 / 70 = 3.3585 moles

3.3585 moles of butanol dissolved in 4.14 kg of water .

ΔTf = 8.37 x 3.3585 / 4.14

= 6.79⁰C

Depression in freezing point = 6.79

freezing point of solution = - 6.79⁰C .
