Answer:

The single covalent bond is represented by a single ' - ' and it has 2 shared electrons from the the bonding atoms.

Double covalent bond is denoted with '=' and it has 4 shared electrons

Triple covalent bond is denoted by ' _=' and it has 6 shared electrons

Explanation:

In single covalent bond each participating atom contributes one electron each to be equally shared between them in order to form a single covalent bond. Thus a single covalent bond is formed when atoms share 2 electrons together

The double covalent bond is formed when each participating atom contributes two electrons each to be equally shared between them in order to form a double covalent bond. Thus a double covalent bond results from the sharing of 4 electrons together by two atoms. For example the formation of oxygen gas molecule

In triple covalent bonds, 6 electrons are shared and each pair of electrons forms a bond which results in triple covalent bonds. Each atom contributes 3 electrons for equal sharing.

Answer

A *single covalent bond* is formed by sharing one pair of valence electrons.They are less reactive comparatviely and have a high bond length

A *double covalent bond* is formed by sharing two pairs of valence electrons.They are moderately reactive and have moderate bond length.

A *triple covalent bond* is formed by sharing three pairs of valence electrons.They are highly reactive and have a low bond length.

An endergonic reaction with a Δh and Δs can be changed into an exergonic reaction.
zheka24 [161]

Full question:

This question is incomplete, here it is completed:

An endergonic reaction with a ______ ∆H and a ______ ∆S can be changed into an exergonic reaction by decreasing the temperature.

Option A: negative, positive

Option B: negative, negative

Option C: positive, positive

Option D: positive, negative

Answer:

Option B: negative, negative

Explanation:

The change in free energy (ΔG) of a system for a constant-temperature process is

ΔG = ΔH - TΔS

free energy is the energy available to do work. Thus, if a particular reaction is accompanied by a release of usable energy (that is, <u>ΔG is negative</u><u>), it is said to be</u><u> exergonic</u>. On the other hand, if a reaction consumes energy (that is, <u>ΔG is positive</u><u>), it is said to be </u><u>endergonic</u>.

Looking at the equation, we can see that if ΔH is negative and ΔS is negative, then ΔG will be negative only when TΔS  is smaller in magnitude than ΔH. This condition is met when T is small.

ΔG = ΔH - TΔS

           -        -

This means that the reaction proceeds spontaneously at low temperatures. At high temperatures, the reverse reaction becomes spontaneous. An example of that would be the following reaction:

NH₃(g) + HCl(g) → NH₄Cl(s)
