What are the empirical formulas of a) ethylene glycol, a radiator antifreeze, molecular formula C2H6O2 b) peroxodisulfuric acid,

Temka [501]

<h2>The answers are $CH_3O$ and $HSO_4$ </h2>

Explanation:

Given -

a) The molecular formula of ethylene glycol -

$C_2H_6O_2$

∴ The empirical formula of ethylene glycol will be -

$CH_3O$

Given -

b) The molecular formula of per-oxo-disulfuric acid (a compound used in bleaching agents) -

$H_2S_2O_8$

∴ The empirical formula of per-oxo-disulfuric acid will be -

$HSO_4$

Hence, the answers are $CH_3O$ and $HSO_4$ .

Irrigation is a process, in which the crops are supplied with water, to ensure their proper growth. Increased in the irrigation supply can be because of the environmental conditions like hot summer season or may be because of the type of soil is semi arid or arid means the soil does not retains moisture efficiently. This will result in increase in the rate of evaporation of the surface water.
