Similarities and Differences in the order in which electrons are filled in s and d subshells.
Answers
Answer: Each orbital is found on different areas of the periodic table. The s sublevels are found on the first(left) and last(right) columns of the period table which hold a maximum of two electrons since it only has one orbital. First, each orbital can hold a maximum of two electrons. The other three sublevels: p, d, and f respectively have more orbitals, which is why they can hold more electrons. These sublevels of orbitals stand for sharp(s), principle(p), diffuse(d), and fundamental(f) (these are simply the categories of orbitals).
p has 3 orbitals so it can hold 6 electrons max. d has 5 orbitals so it can hold 10 electrons max. f has 7 orbitals so It can hold 14 electrons max.
Here is a picture of these orbital groups so you can understand a little better:

Explanation:
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other, the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:
a ⇒ b
c ⇒ x
So,
The direct rule of three is the rule applied in this case as follows: If the change in water level is 0.05 inches per hour, what is the change in water level after 24 hours?

A meteorologist uses a weather map to explain an upcoming change in weather. The map shows a blue line with triangles approaching a red line with semicircles. Based on the map, which weather prediction is most valid? (1 point) A a significant drop in temperature will occur across the area. B There is no chance of precipitation in the forecast. C Warm temperatures will replace cold temperatures. D Humidity levels will rise.
Answers
Answer:
Option C: Warm temperatures will replace cold temperatures.
Explanation:
In a weather map, a warm front is depicted with a red line and red semi circles while a cold front is depicted with a blue line and blue triangles.
Now, we are told that the map shows a blue line with triangles approaching a red line with semi-circles. This means that the cold front is approaching the warm front.
Now a warm front is simply defined as the transition zone where warm air mass gradually replaces a cold air.
Thus, it means the weather map depicts the fact that warm temperature is replacing cold temperature.
Thus; Option C is correct.
Answer: 1: A cold front moved into the area. 2: It would actually be A. A significant drop in temperature will occur across the area. 3: Movement of large air masses. 4: “A Strong Cold Front Threatens the Region”. 5: a meeting of two air masses with major differences in temperature and moisture.

Calculate the maximum mass of potassium sulfate, K2SO4, that could be formed when 4.9 g of sulfuric acid reacts with excess potassium hydroxide.
H2SO4 + 2KOH → K2SO4 + 2H2O
Answers
Answer:
From 4.9 g of sulfuric acid 8.175 g of potassium sulfate is formed.
Explanation:
Given data:
Mass of H₂SO₄ = 4.9 g
Mass of K₂SO₄ formed = ?
Solution:
Chemical reaction:
H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O
Number of moles of H₂SO₄:
Number of moles = mass/ molar mass
Number of moles = 4.9 g/ 98.1 g/mol
Number of moles = 0.05 mol
Now we will compare the moles of H₂SO₄ with K₂SO₄ .
H₂SO₄ : K₂SO₄
1 : 1
0.05 : 0.05
Mass of K₂SO₄:
Mass = number of moles × molar mass
Mass = 0.05 mol × 174.3 g/mol
Mass = 8.715 g
Thus, from 4.9 g of sulfuric acid 8.175 g of potassium sulfate is formed.

Explanation:
when water changes state from a liquid to a solid is energy absorbed or lost?
Answers
Answer:
Loses
Explanation:
liquid changes into solid, heat is released. The energy released upon freezing, known as the enthalpy of fusion, is a latent heat, and is exactly the same as the energy required to melt the same amount of the solid.
Answer:
Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings.

What is true about warm, saturated air?
It contains less water vapor than cold air.
It contains the same amount of water vapor as cold air.
It does not contain any water vapor.
It contains more water vapor than cold air.
Answers
Answer:
It contains more water vapor than cold air
According to the process of conduction which take place from hot to cold end warm saturated air has more water vapor than cold air.
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .
As per the concept of conduction, warm hair has more water vapor than cold air, thus the correct option is that warm, saturated air has more water vapor than cold air.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 8.12×10²³ molecules are in 1.35 mole of CS[tex]_2[/tex].
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample. There are so many formula for calculating mole.
we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number
number of atoms/molecules=number of moles × 6.022×10²³(Avogadro number)
number of moles of CS[tex]_2[/tex] = 1.35 mol
Substituting all the given values in the above equation, we get
number of atoms/molecules= 1.35 × 6.022×10²³
number of atoms/molecules=8.12×10²³ molecules
Therefore, 8.12×10²³ molecules are in 1.35 mole of CS[tex]_2[/tex].
