Difference b\w bonding nd Antibonding molecular orbitals​
rewona [7]

Answer: Electrons in bonding orbitals stabilize the molecule because they are between the nuclei. They also have lower energies because they are closer to the nuclei. Antibonding orbitals place less electron density between the nuclei. The nuclear repulsions are greater, so the energy of the molecule increases.

1) Compounds:

a) Chemically combined.

b) Components change properties.

c) Fixed proportions.

2) Mixtures:

a) Physically combined.

b) Components retain properties.

c) Variable proportions.

3) Both:

a) Made of elements.

b) 2 or more components.

A compound is a pure substance because its molecule cannot be broken down into simpler particles by physical means. For example water (H₂O) is a chemical compound made of two elements (hydrogen and oxygen).

In chemical change new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.  

There are no chemical bonds between substances in the mixture.,For example, mixture is solution of water and alcohol.

A substance that, when dissolved in water, produces a solution that conducts electric current very efficiently is called:
GREYUIT [131]

Answer:

a strong electrolyte

Explanation:

Let's look at the meaning of the following terms so we can obtain the right answer by means of elimination.

- Strong Electrolyte : A strong electrolyte is a solution/solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution.

- Weak Electrolyte : A weak electrolyte is an electrolyte that does not completely dissociate in aqueous solution. The solution will contain both ions and molecules of the electrolyte. Weak electrolytes only partially ionize in water (usually 1% to 10%)

- Strong ion : Strong ions are cations and anions that exist as charged particles dissociated from their partner ions at physiologic pH. Thus, these ions are “strong” because their ionization state is independent of pH.

Strong Electrolye fits the condition and hence is the correct option.
