Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, the element arranged in order of increasing ionization energy are Gallium, Phosphorus, Chlorine, Fluorine.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same. Two or more than two atoms with different physical or chemical properties can not combine together to form an element.
For neutral atoms, ionization energy is positive, indicating that ionization is indeed an endothermic process. The higher the ionization energy of an atom, roughly speaking, the nearer the outer electrons are to nucleus. The element arranged in order of increasing ionization energy are Gallium, Phosphorus, Chlorine, Fluorine.
Therefore, the element arranged in order of increasing ionization energy are Gallium, Phosphorus, Chlorine, Fluorine.

What is the mass of HF produced by three reaction of 3.0 10 to the 23 molecules of H2 with excess F2
Answer:
It is 20. g HF
Explanation:
H2 + F2 ==> 2HF ... balanced equation
Since the question is asking us to find the mass of product formed, we will want to first convert the molecules of H2 into moles of H2 (we could do this at the end of the calculations, but it's just as easy to do it now).
moles of H2 present (using Avogadro's number):
3.0x1023 molecules H2 x 1 mole H2/6.02x1023 molecules = 0.498 moles H2
From the balanced equation, we see that 1 mole H2 produces 2 moles HF. Therefore, we can now find the theoretical mass of HF produced from 0.498 moles H2:
0.498 moles H2 x 2 moles HF/1 mol H2 = 0.996 moles HF formed.
The molar mass of HF = 20.01 g/mole, thus...
0.996 moles HF x 20.01 g/mole = 19.93 g HF = 20. g HF formed (to 2 significant figures)

Mrs. Moran and Mr. Moran decided to move the cabinet in their dining room. Mrs.
Moran stood on one side, and Mr. Moran stood on the other. They each pushed
with 30 N of force. What was the net force on the cabinet?
Answer:
60N
Explanation:
The net force on the cabinet is 60N.
Net force is that single force that will act like all other forces on a body. The direction of the force and magnitude is very important when resolving forces.
Force applied by Mrs. Moran = 30N
Force applied by Mr. Moran = 30N
Since they each stood on both sides and pushed, the net force will be 30N + 30N = 60N
Answer: 0
Explanation: If they both pushed a force of 30N then it doesn’t add up but instead you subtract. so it’s 0. ur yw ;)

What is the relishing hip between the chemical energy provided by the battery and the electrical energy produced according to the law of conservation of energy
Answer:
Equal
Explanation:
Energy is always conserved in the nature and it is an universal law. According to the law conservation of energy, it is said that energy can never be created out of something and we can never destroy and vanish any energy in any form. Energy in any form can only be transformed to some other forms of energy. This is known as conversion of energy.
In the context, the chemical energy that is produced by the battery and the electrical energy produced should be equal.

El plomo y el yodo forman dos compuestos. En uno, el porcentaje de en masa de plomo es del 44,94% y en el otro es de 62,02%. Calcula los gramos de plomo por gramos de yodo en cada compuesto
Answer:
0.8162 gramos de plomo por gramo de yodo
1.633 gramos de plomo por gramo de yodo
Explanation:
Asumiendo una base de 100 gramos para cada compuesto:
Primer compuesto:
Gramos plomo: 44.94g
Gramos de yodo: 100-44.94g = 55.06g
Así, la masa de plomo por gramos de yodo para el primer compuesto es:
44.94g plomo / 55.06g Yodo =
0.8162 gramos de plomo por gramo de yodo
Segundo compuesto:
Gramos plomo: 62.02g
Gramos de yodo: 100-62.02g = 37.98g
La masa de plomo por gramos de yodo para el segundo compuesto es:
62.02g plomo / 37.98g Yodo =
1.633 gramos de plomo por gramo de yodo

Sucrose is an organic compound made by plants for quick energy. What type of organic compound is sucrose?
1-protein
2-carbohydrate
3-lipid
4-nucleic acid
Answer:
2-carbohydrate
Explanation:
Sucrose belongs to the carbohydrate family. It is a disaccharide which is derived from the condensation of glucose and fructose.
In the body, they are sources of energy for living processes. Upon hydrolysis such disaccharide produces tow monosaccharide units. Food substances that are energy rich will contain some of these organic molecules.Sucrose is a specific type of organic compound classified as a carbohydrate and the correct option is option 2.
Carbohydrates are essential biomolecules made up of carbon, hydrogen, and oxygen atoms. Sucrose, also known as table sugar, is a disaccharide formed by the chemical bonding of one glucose molecule and one fructose molecule.
Plants produce sucrose through photosynthesis and use it as a readily available source of energy. When consumed by animals, including humans, sucrose is broken down into its constituent monosaccharides to provide fuel for various cellular processes.
Thus, the ideal selection is option 2.

In the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is:
Answer:
This question appears incomplete
Explanation:
This question appears incomplete because of the absence of options. However, hydrogen is placed in group 1 because it has just one electron in it's outermost shell (which happens to be the only shell it has) just like every other group 1A/group 1 element. While helium is placed in group 8A/group 18 because it has a completely filled outermost shell (which is also the only shell it has) just like every other element in group 8A/group 18.
In the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is configuration, energy level and properties.
Hydrogen is located in group 1 of the periodic table, although its electronic configuration is 1s¹ and its properties do not correspond to those of the alkali metals of that group. But in its electronic configuration you can see that it has only one electron in its outermost shell (which turns out to be the only shell it has), just like any other element of group 1A /group 1, so it is located in that group.
On the other hand, although the electronic configuration of helium is 1s², this element does not appear in group 2 of the periodic table of elements, but is placed in group 18. This is because it has the energy level complete, so it has the properties of a noble gas, that is, it is inert (it does not react), and it is a colorless and odorless monatomic gas.
In summary, in the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is configuration, energy level and properties.

Global winds can cause a longer summer.
Prevailing winds can cause heavy rains or a dry climate.
Global winds can cause a longer winter.
Answer:
a
Explanation:
Prevailing winds can cause a milder climate with heavy rain is the change that affects the short-term climate in a region, hence option A is correct.
What is wind currents?Concentrated areas of winds are known as air currents. They primarily result from variations in the temperature or atmospheric pressure.
The horizontal and vertical currents are present at the mesoscale, whereas horizontal currents predominate at the synoptic scale.
A region's short-term climate can be dramatically impacted by changes in wind currents. As they move moisture from one place to another, prevailing winds can result in a milder climate with heavy rain.
As a result, the impacted area may see higher precipitation and a more temperate environment.
Therefore, prevailing winds can cause a milder climate with heavy rain can impact the short-term climate in a region.

Compounds are combinations of elements. The combination of those elements is specific to the compound. Some compounds have the exact same elements but in different amounts. Look at C6H12O6, which you hopefully recognize as glucose (think cellular respiration and photosynthesis. But ribose is a 5 carbon sugar and its formula is C5H10O5, which you hopefully recognize (think RNA). They both have the same elements, but have different numbers of each element (sugars all have the 1:2:1 ratio). When you're looking at a formula, it's wise to look for the capital letters. That indicates when a different element is present. For glucose, there's a capital C - carbon, a capital H - hydrogen, and a capital O - oxygen. Behind elements, the subscripts help indicate the number of each element that's present. In glucose, there are 6 carbons, 12 hydrogens, and 6 oxygens. How many carbons, hydrogens, and oxygens does ribose have in its formula?
