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.

Two gases have the same temperature but different pressures. The kinetic-molecular theory does not predict that a. molecules in

olganol [36]

Answer: Option (c) is the correct answer.

Explanation:

Kinetic molecular theory states that particles of a matter are continuously in motion and these molecules represent perfect elastic collision.

So, at the same temperature but different pressures the two gases will have all collisions of the molecules as elastic in nature. It is also possible that molecules in both gases have the same average kinetic energies under given conditions as their molecules might be moving with the same speed.

But we cannot determine the densities of these gases.

Thus, we can conclude that the kinetic-molecular theory does not predict that both gases have the same densities.

1.00 L of a gas at STP is compressed to 473mL. What is the new pressure of gas?

Ratling [72]

Hello!

1.00 L of a gas at STP is compressed to 473 mL. What is the new pressure of gas?

We have the following data:

Vo (initial volume) = 1.00 L

V (final volume) = 473 mL → 0.473 L

Po (initial pressure) = 1 atm (pressure exerted by the atmosphere - in STP)

P (final pressure) = ? (in atm)

We have an isothermal transformation, that is, its temperature remains constant, if the volume of the gas in the container decreases, so its pressure increases. Applying the data to the equation Boyle-Mariotte, we have:

$P_0*V_0 = P*V$
