Answer: See attachment.
Explanation:
Exceptions to the octet rule fall into three categories:
- An incomplete octet.
- An odd number of electrons.
- More than eight valence electrons around the central atom.
In addition to the 3s and 3p orbitals, xenon also has 3d orbitals that can be used in bonding. These orbitals enable xenon to form an expanded octet.

All the elements beyond uranium, the transuranium elements, have been prepared by bombardment and are not naturally occurring elements. The first transuranium element neptunium, NpNp, was prepared by bombarding U−238U−238 with neutrons to form a neptunium atom and a beta particle.

Answers
Answer and Explanation :
Paramagnetic are those which has unpaired electrons and diamagnetic are those in which all electrons are paired.
(a) V³⁺
The electronic configuration is -
The electrons in 3d orbital = 1 (Unpaired)
Thus, the ion is paramagnetic as the electrons are unpaired.
(b) Cd²⁺
The electronic configuration is -
The electrons in 4d orbital = 10 (paired)
Thus, the ion is diamagnetic as the electrons are paired.
(c) Co³⁺
The electronic configuration is -
The electrons in 3d orbital = 6 (Unpaired)
Thus, the ion is paramagnetic as the electrons are unpaired.
(d) Ag⁺
The electronic configuration is -
The electrons in 4d orbital = 10 (paired)
Thus, the ion is diamagnetic as the electrons are paired.

Intensive properties are physical properties that do not depend on the amount or size of the material being measured. In other words, they remain constant regardless of the quantity of the substance.
The correct answer is b. magnetism.
Out of the options provided:
a. mass is an extensive property because it depends on the amount of the substance. If you have more of a substance, you will have a greater mass.
b. magnetism is an intensive property because it remains the same regardless of the size or amount of the material with the magnetic property.
c. shape is not a standard property used to classify intensive or extensive properties. It is more of a description of the object's form.
d. volume is an extensive property because it depends on the size and amount of the substance. If you have more of a substance, you will have a larger volume.

Answer:
b. Magnetism (sorry im very late)
Explanation:
Intensive properties do not depend on size, no matter what it doesn't. For example, magnetism, density, melting and boiling points, and color. All of those support intensive property.

b.) a material which a wave travels through
c.) an area where coils spread out
d.) the maximum distance a medium moves from its rest position
Answers
Answer:
A.
Explanation:
A wave is a disturbance that moves energy from one place to another. Only energy — not matter — is transferred as a wave moves. The substance that a wave moves through is called the medium. That medium moves back and forth repeatedly, returning to its original position. But the wave travels along the medium

Answer:
1. Al is consumed first and CuSO₄ remains left.
2. The grams of ferric chloride that forms is 14.5 g.
3. The percent yield is 63.1%
4. Trace of impurities present in the reagents, bad manipulations when preparing solutions, etc.
Explanation:
1. The reaction is:
2Al + 3CuSO₄ = Al₂(SO₄)₃ + 3Cu
The number of moles of Al is less than the number of moles of CuSO₄. Therefore, Al is the limiting reagent and CuSO₄ is the excess reagent. This means that Al is consumed first and CuSO₄ remains left.
2. The reaction is:
2Fe + 3Cl₂ = 2FeCl₃
The number of moles of Fe is:
The number of moles of Cl₂ is:
We know that 2 moles of Fe react with 3 moles of Cl₂, thus:
2 moles Fe---------------3 moles Cl₂
0.0895 moles Fe-------X moles Cl₂
Clearing X:
It needs 0.134 moles of Cl₂ but it only has 0.211 moles, thus, Cl₂ is the excess reagent. Fe is the limiting reagent.
2 moles Fe-----------2 moles FeCl₃
0.0895 moles Fe------X moles FeCl₃
Clearing X:
3. The actual yield of FeCl₃ is 9.15 g, the theoritical yield is 14.5 g, thus, ther percent yield is:
%
4. Trace of impurities present in the reagents, bad manipulations when preparing solutions, etc.
