Using your understanding about the patterns between vaporization and condensation, explain why the boiling point and the condens
eimsori [14]

Answer:

Vaporization and Condensation When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules move randomly about, they will occasionally collide with the surface of the condensed phase, and in some cases, these collisions will result in the molecules re-entering the condensed phase.

How are the molecular mass and molar mass of a compound similar and how are they different?
4vir4ik [10]

Answer:

Similarities: both state the mass of chemical species and they have the same numerical value

Differences: molecular mass refers to one single molecule and molar mass refers to one mole of a molecule

Explanation:

The molecular mass is the value of the mass of each molecule and it is measured in mass units (u). It is calculated adding the mass of each atom of the molecule.

The molar mass is the value of the mass of one mole of molecules, which means the mass of 6.022140857 × 10²³ molecules. The unit is g/mol.

For example, we can consider the methane molecule, which has the chemical formula of CH₄:

Molecular mass CH₄ = C mass + 4 x (H mass)

Molecular mass CH₄ = 12.01 + 4 x (1.01)

Molecular mass CH₄ = 16.05 u

Now to calculate the molar mass we multiply the value of the molecular mass by the Avogadro number and convert the units to g/mol:

Molar mass CH₄: 16.05 x \frac{1}{6.022140857 x 10x^{23} } g x 6.022140857 × 10²³ mol⁻¹

Molecular mass CH₄ = 16.05 g / mol

This is an example of Innovation.

<h3>What is an Innovation?</h3>

Innovation is the application of concepts in a way that results in the creation of new products or services or enhances the provision of existing ones. Innovation is defined as "a new or altered entity realizing or dispersing value" by ISO TC 279 in the standard ISO 56000:2020. Others have different definitions, but they all place an emphasis on the novelty, development, and dissemination of concepts or technologies.

The creation of more efficient goods, procedures, services, technology, works of art, or business models, which innovators then make available to consumers, governments, and society as a whole, is a common way that innovation occurs. Innovation and invention are not the same thing, but they are related.
