PLEASE HELP! WILL GIVE BRAINLIEST!!!! match the terms on the left with the terms on the right.

In order for a substance to be an effective mobile phase in a chromatography experiment, it must be able to move different components of a mixture at different rates.

Chromatography involves the separation of substances using the application of the solubility differences in them. It has two phases known as the stationary and mobile phases.

The mobile phase involves motion which is why the ability of substances to move at different rates is a great factor in this type of phase. The Stationary phase on the other hand doesn't involve movement of substances.

Answer:22.37 mph

Explanation:

100 meters = 0.062137 miles

Assume constant speed over the distance.

0.062137 miles in 10 sec

0.372822 miles in 60 sec = 1 minute

22.36932 miles in 60 minutes

22.37 mph rounded to 2 decimals

Answer:

the speed of light (all photons, naturally including those from the CMB, travel at the speed of light relative to you, regardless of frame or your velocity).

But I suspect you’ve asked this question because of a totally understandable but not quite correct set of assumptions about the universe. If my hunch is correct, you understand the CMB a bit like the skin of a balloon, gradually expanding over time. The Earth is a point somewhere in this balloon, and you’re asking about the Earth’s velocity relative to perhaps the center of this balloon. But that’s not quite how the universe works. It’s far more strange.

Our best hypothesis thus far is that the Big Bang happened from a single point. The “space” around us IS that single point. There is no origin point, since everywhere is by definition the origin point. You can see this for yourself by noticing that basically every star and galaxy we can see is - in the long run - moving away from us. And this is true regardless of whether you are on Earth or another star, or any point in the universe. So from this, it doesn’t really make sense to ask what the velocity of the earth is relative to the CMB rest frame, because space itself is expanding. Hopefully haven’t caused too many headaches!

Like other alkali metals, rubidium metal reacts violently with water. As with potassium (which is slightly less reactive) and caesium (which is slightly more reactive), this reaction is usually vigorous enough to ignite the hydrogen gas it produces.

Answer:

To dissolve an ionic compound

Explanation:

the water molecules must be able to stabilize the ions that result from breaking the ionic bond. They do this by hydrating the ions. Water is a polar molecule. ... When you place an ionic substance in water, the water molecules attract the positive and negative ions from the crystal.

I think the lake because of how heat is transferred or something. Just check out the first law of thermodynamics.

Answer:

The basis of the separation by steam distillation is that while the water and organic condensed phases are immiscible, the vapors of both are miscible. Once condensed, the two separate again allowing for an easy separation. As noted above, both liquids and solids can be distilled by steam.

Answer:

Carbon oxides and carbonates are exceptions; they contain carbon but are considered inorganic because they do not contain hydrogen. The atoms of an organic molecule are typically organized around chains of carbon atoms. Inorganic compounds make up 1%–1.5% of a living cell's mass.

Answer:

They are made up of only one type of element, which is carbon, and therefore would fail to be categorized as an organic compound since they are not, in the first place,a compound, but a pure element.

Answer:

As light initially enters the water, it is refracted as in figure (b) and then reflected off the mirror (at the bottom of the glass). Upon exiting the water, the light is bent away from the normal as it passes from water (more dense) and into air (less dense).

This is a combustion reaction of an alkane with oxygen. It is exothermic (

), and can be balanced in normal methods for balancing chemical equations ie ensuring that the total number of atoms of each element is the same on both sides of the equation.
