How is the game pressure of a gas related to its concentration of particles

Found this on the web! "The particles of gases are negligibly small compared to the distance between them, ... This is because an increase in the number of particles in the same volume will increase the number of collisions to the walls of the container, which causes pressure to increase."

hope this helps

much love. :)

Explanation:

According to ideal gas equation, PV = nRT.

When more is the concentration of particles of a gas it means more number of molecules or more number of moles are present.

As pressure is directly proportional to number of moles of a gas. Therefore, when there are more number of moles of a gas then there will be more number of collisions.

As a result, there will be increase in pressure.

Thus, we can conclude that the game pressure of a gas is directly related to its concentration of particles.

When bonds between atoms are broken or formed, what is the outcome?

LuckyWell [14K]

Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. Chemical reactions occur when two or more atoms bond together to form molecules or when bonded atoms are broken apart.

Which type of bond exemplifies a weak chemical bond? covalent bonds in solution hydrogen bonds in solution ionic bonds in solids

vova2212 [387]

Covalent bonds in solution, hydrogen bonds in solution, ionic bonds in solids, nonpolar covalent bonds in solids- the weakest bond is hydrogen bond.

What is a chemical bond?

A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. In covalent bonds, the electrons are shared, whereas in ionic bonds, the electrostatic attraction of two ions with opposing charges forms the link. Strong bonds, also known as primary bonds, include covalent, ionic, and metallic ties. Weak bonds, also known as secondary bonds, include dipole-dipole interactions, the London dispersion force, and hydrogen bonds.

Since there is no necessity for an electron exchange during formation, the hydrogen bond is weak. As a result, it is simpler to break apart a hydrogen connection between two molecules.

To maximize the yield in a certain manufacturing process, a solution of a weak monoprotic acid that has a concentration between

stira [4]

Answer: C 115 ml

Explanation:

If you have a solution of a monoprotic acid, it means that it has the form HA (just one Hydrigen atom). Therefore, one molecule of acid is going to react with just one molecule of NaOH.

So, if you have a solution of 100 ml of 0,2 HA acid, it is going to react with a 100 ml of 0,2 M NaOH solution. Beacause we know that the acid can be a little more concentrated than 0,2 M (0,2-0,3), it probably needs a little more than 100 ml of NaOH to react. So, the answer is C.

in 100 ml of 0,2M acid you can find 0,002 mol of HA

in 100 ml of 0,3 M acid you can find 0,003 mol of HA

in 100 ml of 0,2 M NaOH you can find 0,002 mol of NaOH

the answer can not be 200 because in 200 ml of 0,2 M NaOH there are 0,004 mol of NaOH, which is more than 0,003 mol.
