Which of the following bonds can form between atoms of equal electronegativity? A) Covalent bond B) Ionic bond C) Hydrogen bond D) Metallic bond

Answers

Answer 1

Answer:

Final answer:

A covalent bond can form between atoms of equal electronegativity, where electrons are shared between the atoms.

Explanation:

The bond that can form between atoms of equal electronegativity is a covalent bond.

In a covalent bond, atoms share electrons to achieve a full outer electron shell. This type of bond occurs between nonmetallic elements or between identical atoms.

For example, in a σ (sigma) bond between two hydrogen (H) atoms, each hydrogen atom contributes one electron to the bond, resulting in a shared pair of electrons. Since hydrogen atoms have the same electronegativity, the bond is covalent.

Which is a product of a condensation reaction? 1. O2 2. CO2 3. H2 4. H2O

Answers

The correct answer is H2O, it is a product of a condensation reaction. It is a type of chemical reaction where two molecules combine to form a larger molecule together with a loss of a small molecule. Usually, this small molecule is water.

Answer:

$H_(2)O$ is a product of a condensation reaction.

Explanation:

In a condensation reaction, two molecules are combined to produced a large molecules along with removal of a water molecule.

For an example, let's consider aldol condensation reaction.

In aldol condensation reaction, an enolate anion reacts and combines with an aldehyde or ketone molecule follwed by dehydration. In that dehydration step , $H_(2)O$ gets removed and an unsaturated carbonyl product is formed.

Usually, $O_(2),CO_(2) and H_(2)$ are produced as a by product of a decomposition reaction.

Metallic bonding is possible because the electrons

Answers

It is possible because the electrons in the energy level furthest from the nucleus delocalise, this leaves behind positively charged metal ions which are attracted to the negatively charged electrons that now move around the lattice freely

Alpha, beta, and gamma radiation are all examples of

Answers

Answer:

These all are example of ionizing radiations.

Explanation:

Alpha beta and gamma radiations are the examples of ionizing radiations. When an atom is an excited state and having high energy, the atom is in unstable state. The excess of energy is released by the atom to get the stability. The released energy is in the form of radiations which may include alpha, beta, gamma, X-ray etc.

Alpha radiations:

Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number 4 less than and atomic

number 2 less than the starting atom.

Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.

Beta radiations:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.

The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiations.

Gamma radiations:

Gamma radiations are high energy radiations having no mass.

These radiations are travel at the speed of light.
Gamma radiations can penetrate into the many materials.
These radiations are also used to treat the cancer.
Lead is used for the protection against gamma radiations because of its high molecular density.
The lead apron are used by the person when treated with gamma radiations.
Lead shields are also used in the wall, windows and doors of the room where gamma radiations are treated, in-order to protect the surroundings.
