5. Which statement is true about electronegativity?

Chemistry
1 answer:
Anit [1.1K]2 years ago
3 0

Answer:

Electronegativity generally increases from left to right across a period,

Explanation:

The true statement from the given choices is that electronegativity generally increases from left to right across a period.

Electronegativity is the measure of the relative tendency with which an atom of the element attract valence electrons in a chemical bond.

Across a period electronegativity increases from left to right and decreases down the group.

This is due to reduction in metallic properties as we move across the period from left to right.

Dimethyl sulfide is the most abundant biological sulfur compound emitted to the atmosphere. It is produced by phytoplankton and
iogann1982 [59]

The structure of Dimethyl sulfide is H3C-S-CH3. It is produced naturally by some marine algae.

<u>Explanation:</u>

  • DMS or dimethyl sulfide is formed by using two methyl groups combined with one sulfur atom. It is an organosulphur compound with a structural formula H3C-S-CH3.
  • Most abundant biological sulfur compounds emitted to air and oceans by phytoplankton.
  • DMS is produced naturally by the waste of dimethyl sulphoxide which is disposed into the sewer causing environmental odor problems.
  • It is a flammable liquid that boils at 37 degrees celsius and a disagreeable smell produced from the cooking of certain vegetables also indicates bacterial contamination in the production of malt and brewing.

Sodium carbonate (NaCO3) is sometimes used as a water-softening agent. Suppose that a worker prepares a 0.730 M solution of NaCO
elena55 [62]

Answer : The mass of solute in solution is 1.09\times 10^2g.

Solution : Given,

Molarity = 0.730 M

Volume of solution = 1.421 L

Molar mass of sodium carbonate = 105.98 g/mole

Formula used for Molarity :

Molarity=\frac{w}{M\times V}

where,

w = mass of solute

M = Molar mass of solute

V = volume of solution in liter

Sodium carbonate is solute and water is solvent.

Now put the given values in above formula, we get the mass of solute in solution.

0.730mole/L=\frac{w}{(105.98g/mole)\times (1.412L)}

By rearranging the terms, we get

m=109.247g=1.09\times 10^2g

Therefore, the mass of solute in solution is 1.09\times 10^2g.
