The diagram best shows the magnetic field around the bar magnet is the diagram in option B.
<h3>What is the magnetic field?</h3>
The magnetic field refers to the region in space where the influence of a magnet can be felt. We know that strength of magnet can be seen by following the magnetic lines of force. The more the magnetic lines of force, the stronger the magnetic field especially when the line are packed closely together.
Looking at the diagrams of the magnetic lines of force, it must be recalled that the magnetic lines of force runs from the north pole to the south pole and not the other way round.
Thus, the diagram best shows the magnetic field around the bar magnet is the diagram in option B.

Answer: The mass of
produced is, 149 grams.
Explanation : Given,
Mass of
= 354.2 g
Molar mass of
= 278 g/mol
Molar mass of
= 58.5 g/mol
First we have to calculate the moles of ![PbCl_2](https://tex.z-dn.net/?f=PbCl_2)
Now we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 3 moles of
react to give 6 mole of
So, 1.27 moles of
react to give
mole of
Now we have to calculate the mass of
Therefore, the mass of
produced is, 149 grams.
Once the solution is prepared, water is now considered as the solvent of the solution. On the other hand, NaCl is the solute. The solvent is a substance that dissolves other substances. It has a larger composition with respect to the other components in the solution.
Answer:
Explanation:
Magnetic fields can be measured in various ways. If this device, called a dip meter, is first aligned in the direction of the magnetic meridian as defined by a compass, the needle lines up with the total field vector and measures the inclination angle I
