Answer:

Both particles A and B

Explanation:

A nucleus contains both protons and neutrons .

But protons are positively charged whereas neutrons have no charge.

[tex].[/tex]

Both particles A and B are most likely present inside the nucleus of the atom. Therefore, option (c) is correct.

The nucleus of an atom contains the particles protons and neutrons. Both the solid particles in an atom are responsible for 99.9% of the mass in the nucleus.

The protons are the positively charged particles that lie inside the nucleus. Therefore, the nucleus of an atom has a positive charge on it while the negatively charged electrons rotate around the nucleus.

The neutrons do not carry any charge. So we can say that the neutrons are neutral. Therefore, the charge on the nucleus is only due to protons.

The atomic powers which are holding the protons and the neutrons inside the nucleus are also vast. The protons are prsent very close to each other inside the tiny nucleus, so the electrostatic forces of repulsion act in the nucleus.

Therefore, particles with no charge and positive charge are most present in the nucleus of the atom.

Answer:

Relative dating is based on the positions of fossils in rock layers. Lower layers were laid down earlier, so they are assumed to contain older fossils. This gives the fossil an approximate age in years. Absolute dating is often based on the amount of carbon-14 or other radioactive element that remains in a fossil up until extinction.

Relative dating is a method of dating where the geologic events are arranged and the rocks are left behind in a sequence. They function on the basis of the stratigraphy and don't provide us with actual numeric data.

Answer:

A bottle that is sealed would have the highest concentration.

Explanation:

When you put a gas into a container, the concentration or the amount of mol inside the bottle would be highly concentrated. If you open the bottle, the CO2 would spread outwards and leave the bottle giving more room between each molecule. The longer you open the bottle, the less concentrated the gas will be.

We know that the sunscreen preparation contains a 2.7% by mass of Benzyl Salicylate. From this, we will find that they need 1.559 kg of Benzyl Salicylate to make 340 tubes of sunscreen.

The initial data means that if the total mass of sunscreen is M, then the mass of Benzyl Salicylate will be 2.7% of M, or:

(2.7%/100%)*M = 0.027*M

Now, we know that a tube contains 6.0 oz of sunscreen.

Then M = 6.0oz

A tube contains:

0.027*6.0oz = 0.162 oz.

Then in 340 tubes, we will need 340 times 0.162 oz of Benzyl Salicylate, this is:

340* 0.162 oz = 55.08oz

And we want this quantity in kg.

Knowing that:

1oz = 0.028kg

Then 55.08oz is 55.08 times 0.028kg:

55.08*0.028kg = 1.559 kg

So they will need  1.559 kg of Benzyl Salicylate to make 340 tubes of sunscreen.

Answer:

m=104000

Explanation:

by 1km=1000m

104km=?

Now

104km=104×1000m

=104000m

Therefore,m=104000 ans

104 kilometers is equal to 104,000 meters.

A conversion factor is a ratio that shows how two different units of measurement relate to each other. You can convert a value from one unit to another by multiplying or dividing the original value by a conversion factor.

For example,

Since there are 1000 meters in a kilometer, we need to multiply the distance in kilometers by 1000 to convert it into meters.

So, to convert 104 kilometers to meters:

104 Km * 1000 = 104,000 meters

Therefore, 104 kilometers is equal to 104,000 meters.

1/5 is the dilution of reagent A in water.

Explanation:

       [tex]D.F.=\frac{V_f}{V_i}[/tex]

       Where:

                 D.F = Dilution factor

                 [tex]V_f[/tex] = Final volume of the diluted solution

                 [tex]V_i[/tex]= Initial volume of the undiluted solution

Given:

4 parts of the reagent and 16 parts of water are mixed together to form a diluted solution.

To find:

The dilution of reagent A in water

Solution:

Parts of reagent A =[tex]V_i = 4[/tex]

Parts of water = 16

Final volume of solution = [tex]V _f = 4 + 16 = 20[/tex]

The dilution factor of reagent A:

[tex]D.F=\frac{20}{4}=5[/tex]

The dilution of the reagent A = [tex]1:5=\frac{1}{5}[/tex]

Explanation:

i guessed cause im just that cool

It is due to low volume of electron that causes large distance between two electrons.

When the added electron goes to smaller quantum level, the repulsive force between two electrons is less because the electron which is added occupies small space due to less volume so there is a large distance between two electrons that leads to less force of repulsion.

If the electron has more volume so it occupies more space and there will more repulsive force between two electrons so that's why we can say that the smaller volume of electron is the reason of less repulsive force.
