Correct answer is: A double bond between carbon atoms is longer than a triple bond between carbon atoms.

Reason:
In a carbon-carbon double bonded system, each carbon has undergoes sp2 hybridization. Thus, it bond order of system is 2. While in case of carbon-carbon bonded system via triple bond, each carbon atom undergoes sp hybridization. The bond order in this case is 3. Further, extent of overlap in sp hybridized orbitals is more as compared to sp2 hybridized orbitals. Hence, a double bond between carbon atoms is longer than a triple bond between carbon atoms.

Physical property of water at room temp

Galina-37 [17]

In nature, water exists in the liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at 0 degrees Celsius and 1 atm of pressure. At room temperature (approximately 25 degrees Celsius), it is a tasteless, odorless, and colorless liquid.

How does the kinetic-molecular theory explain the following properties of liquids:

Tcecarenko [31]

Answer:

"Kinetic energy of the gas is more as compared to that of the liquids. But when compare it to the solid, kinetic energy of liquid is more."

Explanation:

a) Relatively high density : This happens as a result of the tight or packed or can be say close arrangement of the particles.

b) Ability to diffuse : As we know that in gases the constant and the random motion of the particles of the liquid leads to diffusion. But it is very slow as compared to the gases and also porque liquid particles are close together.

c) Ability to evaporate:This happens as a result of the molecules of the liquid having different kinetic energies with particles having higher than that of the average energies that move faster.

You need a 20% alcohol solution. on hand, you have a 240 ml of a 15% alcohol mixture. you also have 40% alcohol mixture. how muc

juin [17]

0.15*240=36 ml of alcohol in 240 ml of a 15% alcohol mixture
0.4x = ml of alcohol in x ml of a 40% alcohol mixture
0.2(x+240)= ml of alcohol in (x+240) ml of a 20% alcohol mixture

0.15*240 + 0.4x = 0.2(x+240)
36+0.4x=0.2x+48
0.2x = 12
x=12/0.2=120/6=20 ml of a 40% alcohol mixture

Chromium has four naturally occurring isotopes. cr-50 (mass of 49.946 amu and 4.35% abundance); cr-52 (mass of 51.941 amu and 83

satela [25.4K]

The average atomic mass of chromium to 3 decimal points is 52. 055 g. mol.

<h3>What is the average atomic mass?</h3>

"The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass, also known as atomic weight."

Given the different isotopes of chromium.

The four isotopes of chromium are cr-50, cr-52, cr-53 cr-54.

The average atomic mass will be

Let us take the weighted average of your isotopes:

50 × 0.0434 + 52 × 0.8379 + 53 × 0.095 + 54 × 0.0237 = 52. 055 g.

Thus, the average atomic mass of chromium is 52. 055 g.
