Which factor is generally responsible for high melting points?

Chemistry

nikdorinn [45]3 years ago

Answer: Option (A) is the correct answer.

Explanation:

Melting point is defined as the point where a solid substance starts to convert into a liquid state.

For example, ice starts to melt at a temperature above 0 degree celsius.

More strong is the intermolecular forces of attraction present in a substance more will be the heat required by it to break the bonds between its particles. So, that its state can be changed.

For example, a solid substance required more heating as compared to a liquid substance to change its state.

Thus, we can conclude that high intermolecular forces of attraction is generally responsible for high melting points.

A. High intermolecular forces of attraction. If there are high intermolecular forces, the molecules will need large energies to escape into the liquid. The substance will nave a high melting point.

The other options are <em>incorrect </em>because they are <em>weak force</em>s. They would cause <em>low melting points</em>.

How is calculating a weighted average
kirza4 [7]

Answer:

The Key difference between average vs weighted average is that simple average is nothing but simply adding up all the observation values and dividing the same by the total number of observations to calculate the average whereas weighted average is an average where each observation value will have a frequency assigned.

How does the volume of water change the solubility of sodium chloride in simple words?
kupik [55]

Answer:

When sodium chloride dissolves in water to make a saturated solution there is a 2.5 per cent reduction in volume. ... The solubility of salt does not change much with temperature, so there is little profit in using hot water.

The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction. This can be gleane
GenaCL600 [577]

Answer : The total mass of oxygen gas released in the reaction will be, 12.8 grams

Explanation :

Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The balanced chemical reaction will be,

2MgO\rightarrow 2Mg+O_2

According to the law of conservation of mass,

Total mass of reactant side = Total mass of product side

Total mass of 2MgO = Total mass of 2Mg+O_2

or,

Total mass of 2MgO = Mass of 2Mg  + Mass of O_2

As we are given :

Total mass of MgO = 16.12 grams

The mass of Mg = 9.72 grams

So,

Total mass of 2MgO = Mass of 2Mg  + Mass of O_2

2\times 16.12g=2\times 9.72g+\text{Mass of }O_2

\text{Mass of }O_2=32.24g-19.44g=12.8g

Therefore, the total mass of oxygen gas released in the reaction will be, 12.8 grams

Under which conditions (in terms of kinetic energy) does boiling occur? How is the kinetic energy in the liquid increased?
Simora [160]

Explanation:

Boiling is defined as a process in which vapor pressure of a liquid substance becomes equal to the atmospheric pressure.

During this change liquid and vapors remain in equilibrium and the equation for this change is as follows.

            X(l) \rightleftharpoons X(g)

Therefore, when boiling takes place then average kinetic energy of particles in liquid phase equals to the average kinetic energy of particles in vapor phase.

Hence, we can increase the kinetic energy of particles in liquid phase by increasing the temperature because kinetic energy is directly proportional to temperature as follows.

                       K.E = \frac{3}{2}kT
