Answer:
igneous,sedimentary,and metamorphic
Explanation:
Rocks are collections of minerals of various sizes and types. The three main rock types are igneous, sedimentary, and metamorphic. Crystallization, erosion and sedimentation, and metamorphism transform one rock type into another or change sediments into rock.

a boiling pot of soup with a lid on it to keep in the energy is what type of system?
Answer:
Closed system. :)
Explanation:
When the lid on the pot of soup is closed, it means matter can no longer escape, which in turn, makes it a closed system. I hope this helps, please let me know if you have any further questions

What happens when the light enters the water and then when it leaves the water?
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).

According to scientific thought, what is a theory? O a a confirmed hypothesis O an unsubstantiated idea an interpretation supported by facts O a controversial guess
Answer:
- an interpretation supported by facts.
Explanation:
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world.

Are two atoms of the same element identical?
Answer
Two atoms of the same chemical element are typically not identical. ... Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are differenter:
Explanation:
Explain why rubidium is less reactive than caesium.
Answer:
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.

What does a flat, horizontal line mean on a
DISTANCE-time graph?
Speeding up
Travelling at a constant speed
Not moving (motionless, stationary)
Answer:
Explanation:
A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!
The fastest man can run 100 meters in 10 seconds. What is his speed in miles per hour?
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
What type of elements are found in each group?
Group 1 of the periodic table consists of hydrogen and the alkali metals. ...
Group 2 consists of the alkaline Earth metals. ...
Groups 3–12 contain transition metals. ...
Groups 13–16 each contain at least one metalloid. ...
Group 17 contains halogens. ...
Group 18 consists of noble gases.
Answer:
Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.

What causes an earthquake?
Answer:The earths plates shifting
Explanation: The movement releases stored-up 'elastic strain' energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

Explain how CMB is observed on the Earth?
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!

why all carbon containing atoms are not organic?
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.
Combustion reactions take place between fuel and oxygen and produce carbon dioxide and water. Balance

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

in order for a substance to be an effective mobile phase in a chromatography experiment, it must be able to move
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.

what phenomenon is the basis behind the ability to separate miscible liquids by distillation?
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 for c plsssssss
Answer:
D has 18 electrons (since atomic number = protons = electrons)
[Ne]3s² 3p⁶ (spdf electron configuration)2, 8, 8 (basic electron configuration) ArgonE has 20 electrons
[Ar]4s² (spdf electron configuration)2, 8, 8, 2 (basic electron configuration)CalciumExplanation:
In spdf form, we are basically spreading out the total number of electrons over the different spdf orbitals. While doing this we have to remember that an s-orbital holds 2 electrons max, a p-orbital holds 6 electrons max, a d-orbital holds 10 electrons max, and an f-orbital holds 14 electrons max.
Based on energy levels, the orbitals are filled in the following order:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, and 7p
So for example Argon with 18 electrons would be filled in the following way:
1s², 2s², 2p⁶, 3s², 3p⁶.
This can be abbreviated using the configuration of the previous Noble gas for example [Ne] = 1s², 2s², 2p⁶
∴ we can express Argon as [Ne] 3s², 3p⁶.
