Answer:

cycloocta-1,4-diene- isolated double bond

cycloocta-1,3-diene- conjugated double bond

cyclodeca-1,2-diene- cumulated double bond

cycloocta-1,3,5,7-tetraene- conjugated double bond

cyclohexa-1,3,5-triene (benzene) - conjugated double bond

penta-1,2,4-triene- cumulated and conjugated double bond

Explanation:

A conjugated double bond is a system that contains alternate double and single bonds. It is renowned for its unusual stability.

A cumulated double bond is a double bond system involving about three atoms e.g C=C=C.

An isolated double bond is a system of double bonds separated by more than one single bond.

Which of the following IS a part of the Kinetic Molecular Theory (KMT)?

Arisa [49]

The statement that is a part of Kinetic Molecular Theory (KMT) is Molecules in a gas move rapidly. That is option B.

<h3>What is Kinetic Molecular Theory (KMT)?</h3>

Kinetic Molecular Theory (KMT) is defined as the theory that describes the physical behaviour of gases.

The Kinetic Molecular Theory (KMT) include the following:

Ideal gas molecules are constantly moving;

They have negligible volume;

They have negligible intermolecular forces;

They undergo perfectly elastic collisions; and

They have an average kinetic energy proportional to the ideal gas's absolute temperature.

Therefore, the statement that is a part of Kinetic Molecular Theory (KMT) is Molecules in a gas move rapidly.

What is the temperature of 0.55 mol of gas at a pressure of 1.5 atm and a volume of 12.6 L ?

Taya2010 [7]

Answer:

The temperature is 419,1 K

Explanation:

We use the formula PV=nRT T=PV/nR

T=1,5 atm x 12,6 L/0,55 mol x 0,082 l atm/K mol

T= 419,0687361 K

When the fish-tank water has a pH of 8.0, the hydronium ion concentration is 1.0 × 10-8 mole per liter. What is the hydronium io

Oduvanchick [21]

You must know and use the formula for pH.

pH = - log [H3O+], where [H3O+] is the molar concentration of hydronium ion.

So, when pH is 8.0 => 8.0 = - log [H3O+] and you can use antilogarithm (the inverse function of logarithm) to find [H3O+], in this way:

[H3O+] = 10^-8 = 1 * 10 ^-8 M

When, pH = 7.0 =>

7.0 = - log [H3O+] => [H3O+] = 1 * 10^ -7 M

Answer: 1*10^-7 mole / liter
