<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.

What is the empirical formula for a compound that is 29.44\% calcium, 23.55% sulfur, and 47.01% oxygen? This compound is a commo
PSYCHO15rus [73]

Answer:

Empirical formula is CaSO₄.

Explanation:

Given data:

Percentage of calcium =29.44%

Percentage of sulfur = 23.55%

Percentage of oxygen = 47.01%

Empirical formula = ?

Solution:

Number of gram atoms of Ca = 29.44 / 40 = 0.74

Number of gram atoms of S = 23.55 / 32 = 0.74

Number of gram atoms of O = 47.01 / 16 = 3

Atomic ratio:

            Ca                      :        S                :         O

           0.74/0.74           :     0.74/0.74      :       3/0.74

               1                     :          1              :          4

Ca : S : O = 1 : 1 : 4

Empirical formula is CaSO₄.

In the winter , people often buy large bags of rock salt to sprinkle on their walkways . Why do people do this?
slamgirl [31]

The salt causes the water to freeze at a lower temperature. When a solute, aka salt, is introduced to the system, the freezing point is lowered. This makes the water freeze at a lower temperature.
