Question

2. What kind of a compounds act as an electrolyte? Explain with an example​

Answer 1

Answer:

When some substances are dissolved in water, they undergo either a physical or a chemical change that yields ions in solution. These substances constitute an important class of compounds called electrolytes. 

Example:-

Sodium chloride - Also known by the formula NaCl, sodium chloride is a compound with equal parts sodium and chloride. It is more commonly known as "salt" or "table salt," and is the major ingredient in the edible salt that is sprinkled on food to make it taste better. Sodium chloride is present in the ocean and is the main thing that makes ocean water taste so salty.

Answer 2

 power of 2, written in mathematics as √2 or 21⁄2, is the positive algebraic number that, when multiplied by itself, equals the number 2. Technically, it is called the principal square root of 2, to distinguish it from the negative number with the same property.

is the length of a diagonal across a square with sides of one unit of length; this follows the Pythagorean theorem. It was probably the first number known to be irrational.[citation needed]

As a good rational approximation for the square root of two, with a reasonably small denominats sometimes used.

the OEIS consists of the digits in the decimal expansion of the square root of 2, here truncated to 65 decimal places:
