Will mark empirical formula for a compound is the radio of the atoms or moles of the elements in a compound

Empirical formula is the lowest whole number ratio of the atoms or moles of the elements in a compound.

Explanation:

Empirical formula:

It is the simplest formula gives lowest whole number ratio of the atoms or moles of the elements in a compound.

For example:

The empirical formula of glucose ( C₆H₁₂O₆) is CH₂O.

The empirical formula of benzene (C₆H₆)  is CH.

Consider  the following example:

The mass of sodium in a compound is 29 g, sulfur is 40.5 g and oxygen is 30.5 g. The empirical formula will be:

Solution:

Number of gram atoms of Na = 29.0/23 =1.261

Number of gram atoms of S = 40.5 / 32 = 1.266

Number of gram atoms of O = 30.5 / 16 = 1.906

Atomic ratio:

Na               :            S                  :    O

1.261/1.261 :       1.266/1.261     :   1.906/1.261

     1          :            1                    :         1.5

Na : S : O = 2  ( 1: 1 : 1.5)

Na : S : O = 2 : 2 : 3

Empirical formula is  Na₂S₂O₃.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
