What causes atoms to have magnetic properties

Chemistry
2 answers:
jonny [76]3 years ago
8 0

Answer:

Moving electrons create magnetic field. The reason that electrons can behave like tiny magnets is the fact that when electrons move, they create a magnetic field.

Spinning electrons. Electrons have a property called spin. ...

Strong and weak electron alignments. Atoms such as iron have most of their electrons aligned in the same direction

Answer:

The motion of electric charges induces magnetism. There are electrons in every atom, particles that bear electric charges. The electrons surround the nucleus, or heart, of an atom, like spinning tops. Their motion induces an electrical current which causes every electron to behave like a microscopic magnet.

Explanation:

species of atoms possess a magnetic moment—that is, that such an atom itself is an elementary electromagnet produced by the motion of electrons about its nucleus and by the spin of its electrons on their own axes.

True or false: The phenolphthalein indicator changes colour close to the point of neutralization which shows the end-point of th
kondaur [170]

Answer:

True

Explanation:

A titration can be defined as the experiment where the volume of known con concentration is mixed into another solution whose concentration is not known.

Most of the titration are acid-base titration. When performing titration the indicator which is used is usually phenolphthalein. The end point of the titration is the point where the indicator changes its color.

In case of acid base reaction, the end point is achieved when the phenolpthalein turns faint pink in color from transparent.

Hence, the given statement is correct, the indicator changes its color close to the end point of titration.

A student estimated the volume of a liquid in a beaker as 200.0 mL. When she poured the liquid into a graduated cylinder she MEA
Taya2010 [7]

Answer:

<h3>The answer is 0.91 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual volume = 198.2 mL

error = 200 - 198.2 = 1.8

So we have

P(\%) =  \frac{1.8}{198.2}  \times 100 \\  = 0.90817356205...

We have the final answer as

<h3>0.91 %</h3>

Hope this helps you

Experimental value of acceleration due to gravity is found to be
KiRa [710]

Answer:

0.33%

Explanation:

From the question given above, the following data were obtained:

Experimental value = 9.842 m/s²

Accepted value = 9.81 m/s²

Percentage error =?

The percentage error in the calculation can be obtained as follow:

Percentage error = |Experimental – Accepted| / Accepted value × 100

Percentage error = |9.842 – 9.81| / 9.81 × 100

Percentage error = 0.032 / 9.81 × 100

Percentage error = 0.33%

Therefore, the error in the calculation is 0.33%
