What is the electronegativity in the determination of the ionic or covalent character of a bond

Chemistry
1 answer:
Paladinen [302]3 years ago
8 0

Polar Covalent is the name used to describe bonds that have both ionic and covalent character because the electrons are shared unequally. The Pauling Scale is used to assign electronegativity to atoms. It ranges from to 4.00 (fluorine).

What is carbon-14 radioactive dating used for
jek_recluse [69]
Hey.

It is used for a prosecutor called carbon dating.This can be used to determine the age of an object.
So carbon 14 decays in biological life and we can find out how old objects are by finding the amount of C14 left.

So the answer is Carbon dating
Hope this helps and happy new year :)

A solution of 100.0 mL of 0.200 M KOH is mixed with a solution of 200.0 mL of 0.150 M NiSO4. (a) Write the balanced chemical equ
Alika [10]

Answer:

2KOH(aq) + NiSO₂(aq) → K₂SO₄(aq) + NiOH₂(s)

Explanation:

This reaction is an example of a <em>double-replacement reaction </em>where the cations of two compounds exchange with its anions. In the reaction:

KOH(aq) + NiSO₄(aq)

There are produced K₂SO₄ and NiOH₂ salts (The last one is insoluble, its state is (s) but K₂SO₄ is very soluble, its state is (aq). The unbalanced reaction is:

KOH(aq) + NiSO₄(aq) → K₂SO₄(aq) + NiOH₂(s)

To balance the potassiums:

<h3>2KOH(aq) + NiSO₂(aq) → K₂SO₄(aq) + NiOH₂(s)</h3>

And now, the reaction is balanced

Use atomic properties to explain the reduction of a less active metal by a more active one:(b) in the molten state. Give a speci
Bad White [126]

The reduction of a less active metal by a more active one is called metal displacement reactions. For example:

Fe + CuSO4 → FeSO4 + Cu

<h3>What is metal displacement reaction? </h3>

Displacement reactions is a reaction which includes a metal and the compound of a other metal. A more reactive metal will push or displace out a less reactive metal from its compound in this displacement reaction. The metal which is less reactive left uncombined after the reaction.

As we know that, electrons are the basis of the chemical reactions. If chemical compound or element A is more easily oxidized than B, then according to the terms of the activity series, the elements which are more easily oxidized can react with more chemicals, since they are able to act as a reducing agents for more chemicals.

Since, Metal ions are positively charged ions as they lose electrons. Some metals give up their electrons more readily than others and become more reactive.

Thus, we concluded that the reduction of a less active metal by a more active one is called metal displacement reactions. For example:

Fe + CuSO4 → FeSO4 + Cu

Glaciers also _____ materials in new places when they melt.
natali 33 [55]

Deposits

Explanation:

Glaciers also deposits materials in new places when they melt.

  • Glaciers are made up of snow flakes that has compressed through time.
  • In temperate and polar regions where they are prevalent, they are powerful agents of denudation.
  • They can erode, transport and deposit earth materials in places.
  • When a glacier retreats by melting, it deposit some of its materials in new places.
  • Most of this sediment are called tillites.
  • They are made up of unsorted materials of different size grains.

Which kind of covalent bond has unequal sharing of electrons
lutik1710 [3]

Polar.

Polar bonds have unequal sharing electrons while nonpolar, the opposite, has equal sharing electrons. This is a tactic typically used to determine whether or not a compound or element itself is polar or nonpolar.

Hope this helps!
