Answer: The correct answer is Option 1.

Explanation:

For the given options:

Option 1: During a phase change

Whenever phase change occurs, the temperature remains constant because the heat is used to overcome the intermolecular forces between the particles.

Option 2: During a pressure change

As we know pressure is directly related to the temperature. So, if the pressure is increased, the temperature will also increase and vice-versa.

Option 3: During a change in kinetic energy

Kinetic energy is directly related to the temperature of a substance. So, if the kinetic energy is increased, the temperature will also increase and vice-versa.

Option 4: During a change in molecular velocity

Molecular velocity is directly related to the temperature of a substance. So, if the molecular velocity is increased, the temperature will also increase and vice-versa.

Hence, the correct answer is Option 1.

Of all the elements, fluorine is the most electronegative and reactive. Fluorine is a diatomic, pale yellow, extremely corrosive, combustible gas with a strong smell. The lightest halogen is it. It produces oxygen and the incredibly corrosive hydrofluoric acid when it combines strongly with water.

<h3>The properties of the oxide and the fluoride?</h3>

1. A mixture of oxygen fluorides with an atomic ratio OF in the range of 1.1-2.04 is generated when fluorine and oxygen mixes are easily circulated through a silent electric discharge.
Depending on where you reside in the UK, fluoride is a naturally occurring mineral that is present in water in variable concentrations. It is added to many types of toothpaste and, in some locations, the water supply through a procedure known as fluoridation because it can aid in the prevention of tooth decay.
Fluoride stops tooth decay by strengthening the enamel's resistance to acid attack. They also quicken the process of good minerals accumulating in the enamel, further delaying the onset of deterioration. Studies also suggest that fluoride may occasionally be able to stop tooth decay that has already begun.

What is the mole fraction of HCl in a solution that contains 0.99 mole HCl and 3.6 mole H2O

marysya [2.9K]

Answer:

0.216

Explanation:

The mole fraction of HCl is the number of moles of HCl (0.99) divided by the total number of moles in the solution.

mole fraction = (0.99)/(0.99 +3.6) = 0.2157

The mole fraction of HCl is about 0.216.
