The magnet can cause the alignment of electron domains in the metal screw driver on rubbing, causing magnetism.

The magnetism in a permanent magnet is produced by magnetic moments of electrons in the magnet's constituent material. The material's atoms are each like tiny magnet bars. As a result of the quantum mechanical effect, the majority of these tiny magnets now prefer to align in a single direction to form domains, consequently magnetizing the entire substance.

Electrons exist in magnetic metals as well, although they are arranged differently. A strong magnet has a magnetic field strong enough to cause residual magnetism in the metal screwdriver by aligning the domains in it on rubbing with the metal.

How many atoms are in 8.28 moles of aluminum?
Lilit [14]

Answer:

49.86 × 10²³  atoms of Al

Explanation:

Given data:

Number of moles of Al = 8.28 mol

Number of atoms = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For 8.28 moles of Al:

1 mole = 6.022 × 10²³  atoms of Al

8.28 mol×6.022 × 10²³  atoms / 1mol

49.86 × 10²³  atoms of Al

In the graph above for the dissociation of a strong acid, why do the bars for H3O+ and A- have the same height as the bar for HA
dimaraw [331]

Answer:

The concentration of HA is the same as concentration of H3O+ and A- produced.

Explanation:

The dissociation equation is given below:

HA(aq) + H2O (l) —> H3O+(aq) + A-(aq)

From the reaction above, we can see that the acid is monoprotic acid i.e it has only 1 ionisable hydrogen atom.

Now, from the balanced equation, we can see that the acid produced equal concentration of H3O+ and A-.

This account for the reason why the bars for H3O+ and A- have the same height as the bar for HA.

Nuclear power plants have the greatest environmental impact during __________. A) operation B) mining C) waste disposal D) const
lyudmila [28]
The correct option is C.
The issue of disposal of waste of nuclear power plants has been a controversial issue for long because of the hazardous effects which these wastes have on human health and the environment. Most of the waste are usually long lived radioactive wastes which can remain active for a very long time and which have detrimental effect on both the environment and the human health.<span />
