The strength of a magnetic field follows _____.

Chemistry

Solnce55 [7]3 years ago

Answer: The correct answer is "law of poles".

Explanation:

Magnetic field lines are the area around the magnet in which the magnetic force can be experienced.

Law of poles: Like poles of the magnets repel each other with the magnetic force of repulsion. Unlike poles of the magnets attract each other with the magnetic force of attraction.

The direction of the magnetic field lines is from north pole to south pole. The strength of the magnetic field varies with the distance from the poles.

The strength of the magnetic field is stronger at the poles. It decreases from the poles.

The strength of the magnetic field does not follow an inverse square law. The gravity field and the electric field follow an inverse square law. The force from the magnet decreases faster than an inverse square law because all magnets have two opposite poles.

The strength of a magnetic field follows law of poles.

Therefore, the correct option is (D).

Write the advantages of modern periodic table write as more as you can and don't copy the same thing​
Tema [17]

Answer:

the advantages of modern periodic tables are given below and explained.

  1. position of hydrogen:since hydrogen has the least atomic number i.e 1 ,it is kept in group 1 of modern periodic table, but still controversial due to its. dual characteristics since it shows the characteristics of borh group 1 and group 17.
  2. position of isotopes :isotopes are element having the same atomic number but different atomic weight . Without any doubt all isotopes of one element and kept in one place.
  3. position of lanthanide and acnitinides: element of Lanthanides series and element of Actinides series are kept below the main block of the periodic table as they have different properties from other elements.
  4. correction of periodic law: some elements do not obey mendeleev periodic law , but when they are arranged according to atomic number they obey the modern periodic law.
  5. position of alkali metals and coinage metals : in modern periodic table , alkali metal are kept in group IA and coinage metals are in group.

hope this helped you☺️

any confusion then comment it and let me know.

actually as I say these points say that the modern periodic table is better than mendeleev periodic table so, don't get confused.

Predict the precipitate that forms when aqueous solutions of silver nitrate an potassium chloride react to form products in a do
Ket [755]
<span>you'll get silver chloride and potassium nitrate. Both of which are soluble, though so you get no precipitate

I thought all chlorides are soluble? </span>

How can heat change matter from a solid to a liquid to a gas?<br> Help ima mark Brainlyest!!
babymother [125]
The heat energy breaks down the bonds between the molecules of the solid so the molecules become looser. Further hearing of the liquid causes the bonds to be broken down and the molecules will move further apart.

Determine how many atoms of pure silver will be created when 19.83 x 1023 atoms of copper are used in the following reaction:
Lubov Fominskaja [6]

Answer:

\boxed{3.966 \times 10^{24}\text{ atoms of Ag}}

Explanation:

(a) Balanced equation

Cu + 2AgNO₃ ⟶ Cu(NO₃)₂+ 2Ag

(b) Calculation

You want to convert atoms of Cu to atoms of Ag.

The atomic ratio is ratio is 2 atoms Ag:1 atom Cu

\text{Atoms of Ag} = 19.83 \times 10^{23}\text{atoms Cu} \times \dfrac{\text{2 atoms Ag}}{\text{1 atom Cu}}\\\\= 3.966 \times 10^{24}\text{ atoms of Ag}\\\\\text{The reaction will produce }\boxed{\mathbf{3.966 \times 10^{24}}\textbf{ atoms of Ag}}
