The intermolecular forces that exist between molecules of NH3, H2O, and HF are hydrogen bonding, dipole-dipole interactions, and London dispersion forces.
The intermolecular forces that exist between molecules of NH3, H2O, and HF are called hydrogen bonding, dipole-dipole interactions, and London dispersion forces. Hydrogen bonding occurs between a hydrogen atom bonded to a highly electronegative atom (such as O, N, or F) and a lone pair of electrons on a nearby molecule. Dipole-dipole interactions occur between molecules with permanent dipole moments, while London dispersion forces occur due to the temporary formation of induced dipoles in adjacent molecules.
Telophase because it is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.
Hope this helps! Please correct me if I'm wrong :)
Metal oxides M2O, peroxide M2O2, and superoxide MO are produced by alkali metals. Metal oxide is also referred to as basic oxide since basic hydroxide is the end result of interactions between metal oxide and water. As a result, their combination with acid produces salt and water in a manner similar to a regular acid-base reaction.
One of the most significant and well-characterized solid catalysts is metal oxide. Metal oxides are used in acid-base and redox processes and are regarded as heterogeneous catalysts.
Several metals are separated from their naturally occurring compounds like oxide and chloride using a breakdown reaction.
Metal oxides are crucial in various additional applications, such as energy production, conversion, and storage, as well as in environmental remediation and pollution monitoring.
Because they react with weak acids to produce salt and water, metallic oxides are basic in nature. They further react with water to create metal hydroxides, which are naturally alkaline due to the production of OH- ions in solution.
Thus, Metal oxides M2O, peroxide M2O2, and superoxide MO are produced by alkali metals.

The symbol of an isotope that atom of its element contains 50 electrons and 70 neutrons is Tin (Sn).
The Isotope may be characterized as one of two or more types of atoms of a chemical element that significantly have the same number of protons but with different numbers of neutrons and therefore different atomic masses.
In a more simple sense, an isotope may be defined as an atom that has the same atomic number but different atomic mass and physical properties.
According to the question,
The number of electrons an atom possesses = 50.
The number of neutrons = 70.
Since, the number of electrons = the number of protons = the atomic mass of an atom = 50.
∴ According to the periodic table, an element having an atomic number of 50 is known as Tin (Sn).
Its atomic mass = the number of protons + the number of neutrons.
= 50 + 70 = 120 amu.
Therefore, the symbol of an isotope that the atom of its element contains 50 electrons and 70 neutrons is Tin (Sn).

≈ 0.31 m/s
v = d/t
= 2m/6.5s
= 0.3079 m/s
≈ 0.31 m/s
Answer:
0.305556 m / s
Explanation:
Speed = distance / time
2 metres = 0.002 km
6.5 sec = 0.00180556 hrs
Therefore,
Speed = 0.002 / 0.00180556
= 1.1 km / hr
= 0.305556 m / s
