Assertion : When the added electron goes to smaller n=3 quantum level, the electron-
electron repulsion is much less.
Reason: The added electron occupies a smaller region of space .
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.

A procedure calls for 4 parts reagent A to 16 parts water.What is the dilution of reagent A in water?
a) 4/16
b) 1/5
c) 1/4
d) 4/12
my guess answer iss 1/4 if incorrect sorr
1/5 is the dilution of reagent A in water.
Explanation:
The dilution factor of the diluted solution is determined by dividing the final volume of the diluted solution by the volume of the undiluted solution.[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
And the dilution is represented as 1 : D.F.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]
1/5 is the dilution of reagent A in water

How to convert 104 Km to M
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.

How does an atom change if all of its electrons are removed?
How does an atom change if all of its electrons are removed?
The atom’s volume increases.
The atom’s mass increases.
The atom becomes positively charged.
The atom becomes negatively charged.
Answer:
c
Explanation:
it becomes positively charged
Answer:
The atom becomes positively charged.
Explanation:
If ALL OF THE ELECTRONS are removed, then there are, no matter what, less electrons than protons in an atom. And, since the atom has less electrons than protons, it becomes positively charged.
Which variable do you change during an experiment? This is often associated with the IF part of the hypothesis.

Answer:
Independant variable
Explanation:
Say you were doing a lab, you wanted to know if fertilizer actually helped a plant grow. The growth of a plant, in this situation, depends on whether you use fertilizer or not. You are changing if you use it or not, so it is the independent variable.
A sunscreen preparation contains 2.70 % by mass benzyl salicylate. If a tube contains 6.0 oz of sunscreen, how many kilograms of benzyl salicylate are needed to manufacture 340 tubes of sunscreen?
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.

Which particle is most likely present in the nucleus of the atom?
O Only particle A
O Only particle C
O Both particles A and B
Both particles B and C
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.
What is the nucleus of an atom?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.

what evidence have you discovered to explain how the fossil record provides relative ages? use the words: mass extinction, superposition, fossils, and relative age
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.
It provides us with the relative ages such as mass extinction the fossils are superimposed. It is based on the position of fossils in the layers of the rocks.Learn more about the discoveries to explain how the fossil record.

Answer:
Friction always slows a moving object down. ... Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding.
