Choose the molecule with the strongest internal bond, (intra-, not intermolecular bond)
Answers
Answer:
A
Explanation:
The molecule with the strongest intramolecular bond is HF. Hydrogen fluoride is the answer due to the strong and highly electronegative nature of Fluorine.
Fluorine is the most electronegative element in nature. When it combines with other substances, due to its electronegative property, it draws most of the electrons closest to itself in the bond. This tendency and ability makes the shared electrons closer the fluorine in the bond. The strong polarization that ensues confers a very strong covalent bond pair on the bond formed.The molecule with the strongest internal bond is HF and the correct option is option A.
An intramolecular bond, also known as a chemical bond, refers to the attractive forces that hold atoms together within a molecule. It involves the sharing, transferring, or rearrangement of electrons between atoms to achieve a more stable configuration.
There are three primary types of intramolecular bonds:
Covalent Bond: In a covalent bond, atoms share electrons to achieve a more stable electron configuration. This bond is formed between nonmetal atoms.Ionic Bond: An ionic bond is formed when there is a complete transfer of electrons from one atom to another. It involves the attraction between positively and negatively charged ions. Ionic bonds typically occur between a metal and a nonmetal.Metallic Bond: Metallic bonding occurs in metals and is characterized by a "sea of electrons" in which the valence electrons are delocalized and free to move within the metal lattice. This allows metals to conduct electricity and exhibit other unique properties.Thus, the ideal selection is option A.

How many cells could form from one frog egg cell and three hours
Answers
Answer:
Some cells, such as the frog egg cells shown here, divide every 30 minutes, and others take as long as a year! The table below compares the length of different cell cycles. 2. With each cell cycle, two cells form from one cell.
After 3 hours, the number of cells formed from one frog egg cell has been 64.
The division of the frog cell occurs every 30 minutes. Thus in 3 hours, the number of divisions occurs:
30 minutes = 1 division
3 [tex]\times[/tex] 60 minutes = [tex]\rm \dfrac{1}{30}\;\times\;180[/tex]
= 6 divisions.
The number of cells formed after n divisions can be given by = [tex]\rm 2^n[/tex]
where n is the number of division cycles.
The number of cells after 6 division cycles = [tex]\rm 2^6[/tex]
The number of cells = 64.
After 3 hours, the number of cells formed from one frog egg cell has been 64.

(4) binding together of two light nuclei
Answers
Answer:
(1) conversion of mass to energy
Explanation:
Nuclear fission: In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.
The primary result of a nuclear fission reaction is the conversion of energy to mass.
What is nuclear fission reaction?Nuclear fission reaction is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The nuclear fission reaction produces gamma photons and releases a very large amount of energy even by the energetic standards of radioactive decay.Hence, option 2 is the answer.

Energy takes on discreet values, we notice that only certain values of energy are allowed hence the line spectrum of the hydrogen atom.
According to the Bohr model of the atom, energy levels within the atom is quantized. Energy quantization implies that energy occurs in discreet packets and do not take on intermediate values.
Because energy takes on discreet values, we notice that only certain values of energy are allowed hence the line spectrum of the hydrogen atom.

What is an electron?An electron is defined as a subatomic particle which is charged negatively either bound to an atom or not it means they are freely found. The nucleus of an atom is made up of electron, proton and neutron. The electron is a basic particle and electron is not made of anything.
The nature of electron is free it means they are present freely in nature and an atom consist of electron.The main function of electron is that function of negatively- charged component of an atom.
The electrons are primary function of current conducting and electrons number as well as atomic number of an element is always same or equal. There is no size of electron but the mass of electron is 9×10^-31.
Therefore, Fluorine has 9 protons and 9 electrons and Iodine has 53 protons and 53 electrons.
