what are electron configurations?
Answer:
In atomic physics and quantum chemistry , the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6, using the notation explained below.
Explanation:
i found it on google
Answer:
To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.
Explanation:
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶, using the notation explained below.

(WILL GIVE BRAINLIEST TO BEST ANSWER) What might a weak acid do to a rock?
When water combines with carbon dioxide in the atmosphere, it will form carbonic acid, which is a weak acid. If this weak acid comes in contact with a rock, it will cause some of the rock to be dissolved. This process can also be referred to as weathering.

Explanation:

What happens immediatesly after you dissolve acid in water? Positively charged hydrogen atoms are released. Positively charged hydrogen atoms are released. Negatively charged hydrogen atoms are released. Negatively charged hydrogen atoms are released. Hydronium ions are released. Hydronium ions are released. Neutrally charged hydrogen atoms are released. Neutrally charged hydrogen atoms are released.
Answer:
The correct answer is A.
Explanation:
The acids with hydrogen atoms in them are the ones that dissolve best in water and when they do, they get diluted, raising their pH level by releasing hydrogen ions (H+) into the solutions.
So when acids get dissolved in water, positively charged hydrogen atoms are released.
The answer is A.

Which of the following does not affect the gravitational force
between the earth and the sun
A
The mass of the earth
B
The mass of the sun
с
The distance between the earth and the sun
D
The net electrical charge of the earth
Answer:
D. The net electrical charge of the Earth.
Explanation:
I remember from middle school. The other three options affect the gravitational force.
The gravitational force between the earth and the sun is dependent on the mass of these two objects as well as the distance between the earth and the sun. Thus, option D is the correct answer.
Why is gravitational pull important?Gravitational pull is referred as a force of attraction beared by the planetary objects. Gravity is responsible for the revolution of planets around the sun in their fixed orbits.
Gravitational pull is important as it keeps the earth revolving around the sun from a safe distance. It holds the earth in position and thus supports the life on earth. Gravity is responsible for optimum atmosphere on earth.
The formation of celestial bodies is also under the influence of gravitational pull. Gravitational force thus is consired as a fundamental force that govers all the celestial bodies.
Gravitational pull is therefore important for the life on earth.

To make a saturated solution, 30 g of sodium chloride is dissolved in 100 g of
water at 293 K. Find its concentration at this temperature.
Answer:
30%
Explanation:
As the formula for finding concentration
= (mass of solute/mass of solution)×100
= (30/100)×100
= 0.3×100
= 30%
The concentration is 30%.

Explanation:
A 30cm3 volume of water was placed in a cylinder, and a stone was dropped in. The water level rose by 35cm3. Is it true that the stone was 5cm3?
Answer:
The volume of stone is 5cm³.
Explanation:
Given data:
Volume of water = 30 cm³
Volume of water and stone = 35 cm³
Volume of stone was 5 cm³ = true or false
Solution:
To check weather the given volume of stone is true or not we have to calculate the volume of stone from given data.
Volume of stone = (volume of water + stone ) - volume of water
Now we will put the values.
Volume of stone = 35 cm³ - 30 cm³
Volume of stone = 5 cm³
Thus the given value is true. The volume of stone is 5cm³.
based on your observation, you can infer that thermal energy transfers to/from objects with higher temperatures to/from objects with lower temperatures

What is the difference between an atom and an element? a An atom cannot be cut into smaller, but an element is a group of atoms that are the same b An atom makes up matter but an element does not c An atom can be combined but an element cannot be combined d An atom can be cut apart but an element cannot
Answer:
c.
Explanation:
One of the main differences between an atom and an element is that an atom can be combined but an element cannot be combined. There are many combinations of atoms that make up different gases, liquids, and solids each with a unique makup. For example, water is made up of two hydrogen atoms and one oxygen atom (H20). Elements are made up of only the same type of atom. For example, the element Hydrogen can only contain hydrogen atoms, while the element Carbon can only contain carbon atoms.

Which of the following can be inferred from the diagram above that shows the dependence of potential Energy on the Internuclear distance between two atoms?
A - The atoms form a bond with a bond length of 25 pm
B - The atoms form a bond with a bond length of 75 pm
с - The net force between the atoms is attractive at 25 pm
D - The net force between the atoms is attractive at 75 pm
Answer:
B - The atoms form a bond with a bond length of 75 pm
From the potential energy diagram of shown, we can infer that the atoms form a bond with a bond length of 75 pm.
When atoms are far away from each other, there exists no interaction whatsoever between the atoms.
However, as the atoms draw closer to each other, the potential energy diagram begins to shift towards an energy minima as we can see from the potential energy diagram.
As the system continues to tend towards this minima, the distance between the atoms decreases. The distance at which the two atoms have the lowest energy is called the bond length.
For this system, such a bond length occurs at 75pm as we can see from the diagram.

The density of a liquid substance is 0.95 g/mL. Three students calculated the density as 0.56 g/mL. Calculate the percent error.
0 41.05 %
41.0 %
O 41.053%
O 41%
Answer:
The answer is 41.05 %Explanation:
The percentage error of a certain measurement can be found by using the formula
[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]
From the question
actual density = 0.95 g/mL
error = 0.95 - 0.56 = 0.39
So we have
[tex]p(\%) = \frac{0.39}{0.95} \times 100 \\ = 41.0526315...[/tex]
We have the final answer as
