Acróstico con la palabra electrolisis (oraciones relacionadas al concepto).

La electrólisis es una reacción química en la que las sustancias compuestas se descomponen en sustancias individuales y / u otras sustancias compuestas bajo la influencia de una corriente eléctrica.

En 1832, Michael Faraday descubrió que en una solución salina las sustancias se descomponen cuando se envía una corriente eléctrica a través de ella y que la descomposición depende de la corriente. Más tarde, este descubrimiento se conoció como la primera ley de electrólisis de Faraday.

Después de esto, Faraday también descubrió que la masa de los elementos formados era directamente proporcional a la masa atómica de los elementos involucrados. Esto reforzó la sospecha de la existencia de electrones. Este descubrimiento se conoció como la segunda ley de electrólisis de Faraday.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
