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.

A person would weigh more on Neptune than on planet earth because the gravitational field strength is stronger on Neptune.
A person would weight more on Neptune than on planet earth because the gravitational force in neptune is more.
What is gravitational force?Gravitational forces is a kind of attraction force which is present between two objects of masses.
Gravitational force on the neptune planet is more as compared to the gravitational force on the earth. So the mass of any object present in the neptune is more than the earth.
Hence a person would weight more on Neptune than on planet earth because gravitatinal force in neptune is more.

Which choices are layers of the atmosphere?

Croposphere
Stratosphere
Mesosphere
Danosphere
Exosphere
Troposphere
Answers
Answer:
Mesosphere
Stratosphere
Thermosphere
Troposphere
Exosphere
Explanation:
The exosphere refers to the farthest region of the atmosphere that gradually fades into space.
The troposphere is the lowest layer of atmosphere. It is the layer where weather changes occur.
The thermosphere is right above the mesosphere but just below the exosphere. It is the layer where photoionization/photodissociation of molecules occurs thereby creating ions. This largely owes to interaction of molecules in this layer with ultraviolet radiation.
The stratosphere is composed of gases. Prominent among them is ozone which serves as a blanket against the sun's ionizing radiation.
The mesosphere lies above the stratosphere but just below the thermosphere. Temperature decreases steadily with height in the mesosphere.

Answers
Answer:
The atom with the smallest mass is the hydrogen atom; its mass is about 10-27 kg. The masses of other atoms go up to about 200 times this. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom.

The identity of the element shown in the model above is determined by the number of -
Answers
Answer:
The number of protons or electrons in its atomic structure
Explanation:
Elements are substances which constitute the building block of matter. The smallest particles of elements that can ever exist are known as atoms. Atoms of different elements are different in their structure properties. This difference is due to to the number of sub-atomic particles present in the atom of each element.
The three sub-atomicparticles are protons, neutrons and electrons. Protons and neutrons are present in the nucleus of an atom, while the electrons revolve around the nucleus in orbits. The identity of each element is determined by the number of protons present in the atomic nucleus of that element. This is known as the atomic number of that element. For neutral atoms, the proton number is equal to electron number.
For the given element, the electron and proton number are respectively 4, therefore, the atomic number of the element is 4. The element with atomic number 4 is Beryllium.

Find the percent of water in Zn3(PO4)2 x 7H2O
Answers
Answer:
24.66%
Explanation:
To find the percent of water (H2O) in the following compound: Zn3(PO4)2. 7H2O
The atomic mass of the elements are as follows:
Zn = 65g/mol
P = 31g/mol
O = 16g/mol
H = 1g/mol
Hence, molar mass of the compound is as follows:
65(3) + {31 + 16(4)} 2 + 7{1(2) + 16}
195 + 95(2) + 7(18)
195 + 190 + 126
511g/mol
Molar mass of 7H2O
= 7(18)
= 126g/mol
Hence, the percent of H2O in the compound is:
Molar Mass of 7H2O/molar mass of compound × 100
= 126/511 × 100
= 0.2466 × 100
= 24.66%
