Answer:

Postulate: Gas particles are extremely small and are far apart.

The activities can be used to demonstrate the postulate is :

Observing colored gas spreading into an inverted jar placed on top of a jar containing the gas

Explanation:

colored gas spreading into an inverted jar placed on top of a jar containing the gas:

This occur because of two reasons:

1. The Gaseous particles are largely spaced . There is large distance between the gases molecule

2. The gases are in continuous motion . Hence they posses very high kinetic energy . This is the reason they mixes quickly if placed in a jar.

This occur by the process of diffusion.

Diffusion of Gases: The intermixing of particles from the region of high concentration to low concentration.

The coloured gas goes into the space between the gaseous molecule present in the jar.(Gases are far apart)

As soon as the coloured gas is mixed in the jar , It spread quickly by diffusion because , The gaseous particles are extremely small and are far apart.

Calculate the pOH of a solution if the concentration of hydroxide ions (OH-) is 1.9 x 10-5M?

OLEGan [10]

Answer:

9.28

Explanation:

pOH refers to a measure of hydroxide ions concentration. pOH tells about the alkalinity of a solution. If pOH is less than 7 then aqueous solutions are alkaline, acidic if pOH is greater than 7 and neutral if pOH is equal to 7.

Concentration of the hydroxide ions = 1.9 x 10-5 M

pH = $-log(1.9\times 10^{-5})=4.72$

pOH = 14 - pH

=14 - 4.72 = 9.28

Read the scenario and then answer the question.

Dvinal [7]

Elias could be standing on the transform boundary.

Answer: Option 1.

Explanation:

Transform boundaries are places where plates slide sideways past one another. At change limits lithosphere is neither made nor devastated. Many change limits are found on the ocean bottom, where they associate fragments of veering mid-sea edges. California's San Andreas issue is a transform boundary.

Transform boundaries are regions where the Earth's plates move past one another, scouring along the edges. Every one of these three sorts of plate limit has its own specific kind of flaw (or break) along which movement happens. Transforms are strike-slip issues. There is no vertical movement—just horizontal.

What two types of matter are closest in density? How do you know? ings.

maks197457 [2]

Answer:

Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.

In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them
