A small container of perfume is opened in a classroom. Soon every student in the room smells the perfume. Explain this in terms of molecules.

Answers

When perfume or cologne is sprayed into the air, it turns into a gas and its particles mix with other air particles that quickly move around the room. This is because gas is the least dense of the three states of matter. It moves quickly into any space or volume because it has the least density. This is called diffusion, when molecules or particles move from areas with high concentration to low concentration areas.

How many grams of ammonia are produced from 6 moles of nitrogen?

Answers

How many grams of ammonia are produced from 6 moles of nitrogen?
Answer: The equation is 3H2 + N2 → 2NH3

If 6 moles of H2 gas react with N2 (assuming all reactants react)

6 * 2/3 moles of ammonia must be produced.

Therefore 4 moles of ammonia can be produced.

Since it is a gaseous equation (all reactants/products are gases), we can just assume that the Mr of the gases do not affect the amounts of the reactants or the products.

Answers

Answer:

Mass and relative abundance of each isotope of that element

The atomic mass of element has been dependent on  mass of each isotopes and their abundance in nature.

The atomic mass has been the mass of neutrons and protons of the element. There has been the presence of the isotopes of the elements, with varying abundance, and varying atomic masses.

The atomic mass of the element has been the relative average atomic mass of the element with respect to the mass of the isotopes and their percent abundance.

The average atomic mass (amu) has been given by:

[tex]amu=M_1A_1\;+\;M_2A_2[/tex]

Where, [tex]M_1A_1[/tex] has been the atomic mass and abundance of isotope 1.

[tex]M_2A_2[/tex] has been the atomic mass and abundance of isotope 2.

Thus, the average atomic mass has been dependent on mass of each isotopes and their abundance in nature.

C. the potassium atom will gain an electron and become smaller as an anion, while the barium atom will lose an electron and become bigger as a cation.

D.

the potassium atom will lose an electron and become smaller as a cation, while the barium atom will gain an electron and become bigger as an anion.

Answers

Answer:

D (But as a heads up, you wrote barium instead of Bromine)

Explanation:

The Potassium atom will lose an electron since its valence shell only has one, while Bromine has 7 electrons in its valence shell. Potassium wants to get rid of its one electron, Bromine wants to gain that one electron to get a full shell.

Potassium will become a CATION with a positive charge (since it lost an electron), Bromine will become an ANION with a negative charge (since it gained an electron)
