Plum-pudding model is different from the model that came after it as the Plum pudding model did not encounter the concept of nucleus it simply says compares atom with a pudding in which electrons are spread around as rasins in a pudding while the model that came after that is Rutherford's model explain that the atom that having nucleus that serves as a center of the atom.
Answer:
Hypercalcemia can cause stomach upset, nausea, vomiting and constipation. Bones and muscles. In most cases, the excess calcium in your blood was leached from your bones, which weakens them. This can cause bone pain and muscle weakness.
Some symptoms are:
Fatigue, bone pain, headaches.
Nausea, vomiting, constipation, decrease in appetite.
Forgetfulness.
Lethargy, depression, memory loss or irritability.
Muscle aches, weakness, cramping and/or twitches.
Answer:
Option d = terpenes
Explanation:
Terpenes:
It is unsaturated hydrocarbons extracted from the plants specially from pine and citrus. These are cyclic compound with the formula C₁₀H₁₆.
1. It is used as a solvent for natural products.
2. It is used in food , cosmetics and pharmaceutical industries.
3. It is very effective ingredients for agricultural pesticides.
4. It is used as a fragrance in perfumes.
5. As a flavoring agent it is also added into the beverages products.
6. It is highly concentrated and used in very small amount to create fragrances.
7. Its high concentration can led to the bad flavor and fragrances.

Answer:
Multivalent Ionic
Explanation:
The type of bond formed between the atoms of two elements can easily be deduced from the magnitude of electronegativity difference between the two bonding atoms.
A summary of electronegativity differences and corresponding types of bonds are shown below as adapted from chemlibretexts, where Δχ is the difference in electronegativity ;
ionic if Δχ ≥ 2.0
polar if 2.0 > Δχ > 0.5
nonpolar if 0.5 > Δχ
To determine the type of bond between Hg and F. Hg has an electronegativity of 2 while F has an electronegativity of 4. the difference in electronegativity (Δχ) is 4 - 2 = 2
This corresponds to a multivalent ionic bond because mercurous ion is the
Hg2^2+ ion and this leads to the formation of Hg2X2 (mercury I fluoride).
