Hydrogen can be obtained economically as a byproduct in the electrolysis of "brine".

A solution of sodium chloride (NaCl)and water (H2O) refers to the brine.The procedure of electrolysis includes utilizing an electric current to achieve a synthetic change and make new chemicals. The electrolysis of brine is a huge scale process used to make chlorine from salt, so three important chemicals, NaOH, Cl2, H2, can be gotten by electrolyzing brine.

There are too many popular methods of production of hydrogen are there. But it is one of the simplest and easy and understandable economic process is electrolysis of water. Since water contains hydrogen and oxygen gases , it has to be separated by electrolysis method. In electrolysis method Hydrogen ions and oxygen ions are separated by the electrolyzer and catched up the cathode and anode electrodes respectively. Since hydrogen ion is positively charged and attracted by the cathode and oxygen ion is negatively charged attracted by the anode. Here the following reactions are undergoing in electrolysis process as follows : 2H^2^0 ----> 2H^2 + O^2

Write a note on Polygenic disorder.

Lorico [155]

Answer:

a note? well alright

Explanation:

Polygenic disease: (the defintion)

A genetic disorder that is caused by the combined action of more than one gene.

Polygenic conditions: hypertension, coronary heart disease, and diabetes.

This is so because such disorders depend on the simultaneous presence of several genes, they are not inherited as simply as are single-gene diseases.

Electromagnetic radiation with a wavelength of 525 nm appears as green light to the human eye. The energy of one photon of this

Sedbober [7]

Answer: The energy of one photon of the given light is $3.79\times 10^{-19}J$

Explanation:

To calculate the energy of one photon, we use Planck's equation, which is:

$E=\frac{hc}{\lambda}$

where,

$\lambda$ = wavelength of light = $525nm=5.25\times 10^{-7}m$ (Conversion factor: $1m=10^9nm$ )

h = Planck's constant = $6.625\times 10^{-34}J.s$

c = speed of light = $3\times 10^8m/s$

Putting values in above equation, we get:

$E=\frac{6.625\times 10^{-34}J.s\times 3\times 10^8m/s}{5.25\times 10^{-7}mm}\\\\E=3.79\times 10^{-19}J$

Hence, the energy of one photon of the given light is $3.79\times 10^{-19}J$

Which atom in the ground state has an outermost electron with the most energy?(1) Cs (3) Li(2) K (4) Na

Leokris [45]

The answer is Cs, no. 2.
Cesium (Cs) is an element which has an outermost electron with most energy in the ground state.
Cesium (Cs), Lithium (Li), Potassium (K), and Sodium (Na) are elements which belong to the group 1 family, the alkali metals. Each has a valance of 1 and wants to release/ lose this e- (electron) to be isoelectronic with the nearest noble gas. Based on the periodic trends, an atom’s radii will raise going down a group.
