ANSWER THE FOLLOWING QUESTION:
_______________________________________

A metal E is stored under kerosene. When a small piece of it is Left Open in the air it catches fire . When the product formed is dissolved in water, it turns red litmus to blue :

✴name the metal E.
✴write the chemical equation for the reaction when it is exposed to air and when the product is dissolved in water .
✴explain the process by which the metal is obtained from its molten chloride

___________________________________________

Plz answer according to 5marks question. ​​

Answer 1

✴name the metal E. = sodium
is chemical formula is = Na+ H*2O------NaO*2 + H*2 gas is released
pls mark as brainliest

Answer 2

this metal is sodium

-2Na+2H2O=2NaOH+H2(water exposure)

-2Na+O2=2NaO+heat(exposed to air)

-electrolysis of sodium chloride:

-brine, a saturated NaCl solution, is the electrolyte

-Hydrogen(H+), Chlorine(Cl-), Sodium(Na+), and Hydroxide(OH-) ions are formed

-sodium goes to the negative steel cathode, while chlorine goes to the positive carbon anode

-the electrolytic cell used for this process is called a Down's electrolytic cell
