Would you expect the shielding effect to be greater in bromine than in chlorine?
A. Yes, because there are more filled orbitals in bromine.
B. Yes, because bromine has a higher atomic number.
C. No, because they are both in the same family.
D. No, because chlorine has a higher electronegativity than bromine.
The shielding effect of bromine is greater than chlorine because there are more filled orbitals than in chlorine.
Shielding EffectThis is the process where by electrons are protected by the pull attraction of the nucleus with the use of electron shells. The shielding effect increases down the group of the periodic table and increases across the period. This is because when you move down the group, there's an increase in the number of shell by 1 and it helps to reduce the effect of nuclear attraction on the electrons. However when you move across the period, there's an increase in the numbers of electron with the same shielding electrons from group 1(a) across the period to group 7(a).
Factor that affect the shielding effect of an electronThe numbers of electrons on the inner shells.Type of orbital which the electron is located.Shielding effect is primarily dependent on the numbers of electrons in the inner shells as well as the type orbitals.

Why does a solid fill only part of a closed jar while the same mass of a gas fills the whole jar?
Answer:
because of atom don't put that as an answer
Explanation:
i need point to do finals
The different behavior of particles in solids and gases, including the intermolecular forces and kinetic energy, leads to solids filling only part of a closed jar while the same mass of a gas fills the whole jar. A solid fills only part of a closed jar, while the same mass of a gas fills the whole jar due to the differences in the behavior of particles in each state of matter.
1. Solid: In a solid, the particles are tightly packed and held in a fixed position. They have a definite shape and volume. The intermolecular forces between the particles are strong, preventing them from moving freely. As a result, solids occupy a specific amount of space within a container.
2. Gas: In a gas, the particles are spread out and move freely. They have no definite shape or volume. The intermolecular forces between the particles are weak, allowing them to move and fill the available space. As a result, gases can expand to fill the entire volume of a container.
When the same mass of a gas and a solid are placed in a closed jar, the gas particles have higher kinetic energy and are more mobile. They collide with each other and the walls of the container, exerting pressure and spreading out to occupy the entire space. Since the intermolecular forces are weak, the gas particles are not constrained by a fixed arrangement.

If 48.3g of iron is completely rusted in oxygen to produce 62.5g of iron (III) oxide, how many grams of oxygen are involved in the reaction?
The amount of oxygen involved in the reaction would be 20.7 g
The equation of rusting of iron is as follows:
[tex]4Fe + 3O_2 ---> 2Fe_2O_3[/tex]
The mole ratio of Fe to O2 is 4:3.
Mole of 48.3 g Fe = mass/molar mass
= 48.3/56
= 0.8625 moles
Equivalent mole of O2 = 0.8625 x 3/4
= 0.6469 moles
Mass of 0.6469 moles O2 = mole x molar mass
= 0.6469 x 32
= 20.7 g

magnesium carbonate and sulphuric acid react to form
Answer:
magnesium sulfate + water + carbon dioxide
Explanation:
how does the value of g on the earth is related to the mass of the earth and its radius drive it
The relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].
What is weight of an object?
The weight of an object is determined as the product of the object's mass and acceleration due to gravity.
F = mg
The gravitational force on objects in the universeThe gravitational force between two objects in the universe is directly proportional to the product of mass of the objects and inversely proportional to the square of the distance between the objects.
[tex]F = \frac{GmM}{R^2} [/tex]
[tex]mg = \frac{GmM}{R^2} \\\\ g = \frac{GM}{R^2} [/tex]
where;
M is the mass of the earth
R is the radius of the earth
Thus, the relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].

substance? (1 point)
O. No, it is not possible because they have different extensive properties.
O Yes, it is possible because they have similar intensive properties.
O Yes, it is possible because they have similar extensive properties.
O No, it is not possible because they have different intensive properties.
They may be the same substance even though they have different volumes and masses.
Intensive properties are the properties are characteristic a substance. Intensive properties are those properties of a substance that can be used to describe the substance.
We can see that the substances have similar reactivity and similar density. This means that they may be the same substance even though they have different volumes and masses.

Please Help giving high points. Perform the following mathematical operation, and eport the answer to the correct number of significant figures. 4568/1.3 = [?]
Answer:
1.3 is the value with the lowest sig figs in your question. So we have 2 sig figs.
4568/1.3 = 3513.84615
Now let's change the answer in sig figs.
We know that trailing zeros don't actually count as part of sig figs.
So we can round the answer to 3500, having the 2 sig figs (3 and 5) while the trailing zeros don't count.
