The order of increasing strength of intermolecular forces can be determined by considering the molecular structure, molecular weight, and polarity of the compounds. The compounds are:

What do mean by intermolecular forces?

Intermolecular forces are the attractive or repulsive forces that exist between molecules in a substance. These forces arise due to the interaction of the electric charges present on the molecules. Intermolecular forces are responsible for many of the physical properties of a substance, such as boiling point, melting point, viscosity, and surface tension.

The ranking of the compounds based on the strength of their intermolecular forces, from weakest to strongest, is as follows:

Methane is a nonpolar molecule, and its only intermolecular force is London dispersion forces, which are relatively weak compared to the other intermolecular forces.

Ethanol is a polar molecule that has hydrogen bonding, dipole-dipole interactions, and London dispersion forces. However, its intermolecular forces are weaker than those of propanone and ethanoic acid due to its smaller size.

Propanone is a polar molecule that has dipole-dipole interactions and London dispersion forces. It is larger than ethanol, so its intermolecular forces are stronger than ethanol's.

Ethanoic acid is a polar molecule that has hydrogen bonding, dipole-dipole interactions, and London dispersion forces. The presence of hydrogen bonding in ethanoic acid gives it the strongest intermolecular forces out of the four compounds.

The change in free energy of a chemical reaction represents the amount of energy that is available to do useful work. It is a thermodynamic quantity that indicates the direction and extent of a chemical reaction.

If the free energy change (ΔG) is negative, the reaction is exergonic, meaning that energy is released and the reaction is spontaneous. This indicates that the products are more stable than the reactants, and the reaction will proceed in the forward direction. Conversely, if the free energy change (ΔG) is positive, the reaction is endergonic, meaning that energy is required for the reaction to occur and it is non-spontaneous. This indicates that the reactants are more stable than the products, and the reaction will proceed in the reverse direction. If the free energy change (ΔG) is zero, the reaction is at equilibrium, meaning that the forward and reverse reactions are occurring at equal rates and the concentrations of reactants and products do not change over time.

Two molecules of CH₃CH₂SH can interact with each other through dipole-dipole interactions because of the polar C-S bond and polar C-H bonds in the molecule. In addition, the molecule can have temporary induced dipoles due to the movement of electrons, leading to London dispersion forces.

Therefore, the main intermolecular forces present between two molecules of CH₃CH₂SH are dipole-dipole interactions and London dispersion forces.

What is Energy?

Energy is a property of objects or systems that can be transferred to other objects or systems, or converted into different forms. It is a scalar physical quantity that can be defined as the ability to do work or produce heat. Energy exists in many forms, such as mechanical, thermal, electrical, chemical, nuclear, and electromagnetic, and can be transformed from one form to another. The SI unit of energy is the joule (J), but other units such as the calorie (cal) or the electronvolt (eV) are also commonly used in different contexts.

To convert energy from joules to calories, we need to use the conversion factor 1 cal = 4.184 J. Therefore, we can calculate the energy of the snack in calories per gram as:

Energy in cal/g = (Energy in J/g) / (4.184 J/cal)

Plugging in the given value, we get:

Energy in cal/g = 14928 J/g / 4.184 J/cal

Explanation:

The Earth's interior and surface play important roles in the formation of all three types of rocks: igneous, sedimentary, and metamorphic.

Igneous rocks form from the cooling and solidification of magma or lava, which originate from the Earth's interior. Magma is formed from the melting of rocks in the Earth's mantle, and it can rise to the surface and erupt as lava. As the magma or lava cools, it solidifies and forms igneous rocks.

Sedimentary rocks form from the accumulation and cementation of sediment particles that have been transported from their original source by wind, water, or ice. The sediment particles are often derived from the erosion of existing rocks, which can be caused by weathering and tectonic forces.

Metamorphic rocks form from pre-existing rocks that have been subjected to high temperature, pressure, and/or chemical alteration, often due to tectonic forces or hydrothermal fluids. The pre-existing rocks can be any type of rock, including igneous, sedimentary, or metamorphic.

In this reaction, two molecules of nitric acid react with one molecule of magnesium hydroxide to produce two molecules of water and one molecule of magnesium nitrate. The coefficients in the balanced chemical equation indicate that two moles of HNO3 react with one mole of Mg(OH)2 to produce two moles of H2O and one mole of Mg(NO3)2.

Answer:

The given balanced equation is not relevant to the conversion of 6.94 mol Na2SO4 to the mass of NaOH. However, we can use stoichiometry to calculate the amount of NaOH required to react with 6.94 mol of Na2SO4.

From the balanced equation, we can see that 1 mole of Na2SO4 reacts with 2 moles of NaOH. Therefore, we can calculate the number of moles of NaOH required as follows:

Number of moles of NaOH = 6.94 mol Na2SO4 x (2 mol NaOH / 1 mol Na2SO4) = 13.88 mol NaOH

Now, we can use the molar mass of NaOH to calculate the mass of NaOH required:

Mass of NaOH = number of moles of NaOH x molar mass of NaOH

= 13.88 mol NaOH x 40.00 g/mol NaOH

= 555.20 g NaOH

Therefore, 6.94 mol of Na2SO4 requires 555.20 g of NaOH to react completely.
