Which Salt is formed when Ammonia reacts with Nitric acid ?

The conversion of 2 - butanol to 2 - nitrobutane​ involves conversion of  2 butanol to 2 - bromobutane and subsequently to 2 - nitrobutane.

In order to convert 2 - butanol to 2 - nitrobutane​, an SN2 reaction is first carried out in which 2 - butanol  is converted to 2 - bromobutane. This reaction proceeds with inversion of configuration at the chiral carbon as expected.

This product is subsequently reacted with silver nitrite in ethanol to yield  2 - nitrobutane​ along side silver bromide. Some alkyl nitrite is also produced as a by product. The components of the mixture are separated by fractional distillation. The scheme of the reaction is shown in the image attached to this answer. This reaction is only applied to primary and secondary alkyl halides.

Answer: k = 5

Explanation:

k = the number of units that f(x) was moved up to get g(x).

We can see from the graph that f(x) was moved five units up.

So k = 5.

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!

8+3+1+12=24

Answer:

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. In redox reaction the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

In the reaction : CuO+H  

2

​

⟶Cu+H  2 O  

n the reaction H2

​

  is oxidized since it has lost electrons and Cu is reduced since it has gained electrons.

The statement "There is space between molecules in a mixture" is true.

A mixture is made up of mixing two or more substances. These mixtures are not mixed chemically, but physically. Both homogeneous and heterogeneous mixtures are possible.

A combination of two or more unrelated substances that is not the result of the chemical fusion is referred to as a mixture. They could be gases, liquids, or solids. The component of a mixture can be easily separated.

A mixture might consist of ingredients in the same phase as one another or in distinct phases. A mixture is homogeneous if the constituent parts are mixed at the same period. A mixture is heterogeneous if it is made up of components that are in different phases.

Thus, the statement is true.

Elements in the same group have similar properties because their electron configurations are similar. In particular they have the same number of valence electrons, which are the in the outermost (highest energy) s and p orbitals.

Chlorine reacts in a similar way to bromine as they belong to same group of periodic table.

Reactivity in chemistry is indeed a measurement of how easily a material reacts chemically. The chemical may react alone or in conjunction with neighboring atoms as well as compounds, and in either case, energy will typically be released. The most reactive substances and elements have the potential to spontaneously or explosively ignite.

Since bromine and chlorine electron configurations are similar, elements of the same group exhibit comparable characteristics. The amount of valence electrons, that are located inside this outermost (highest energy) p and s orbitals is particularly similar.

Therefore, chlorine reacts in a similar way to bromine as they belong to same group of periodic table.

Atoms that have the same number of valence electrons (belong to the same group of the periodic table) have similar properties. Hydrogen and Helium are exceptions.  The first shell is filled with 2 electrons which makes Helium a Noble Gas and Hydrogen is a gas thus not a Group 1 metal.

The given atom has 2 valence electrons (a group 2 element).

∴ the atoms with similar properties to that of the given atom would also have 2 valence electrons:

I - filled 1st shell thus noble gas ❌

II - 3 valence electrons ❌

III - 4 valence electrons ❌

IV - 2 valence electrons ✅

Checking my answer:

If we check the periodic table, the atom given is Be (Alkali Earth Metal)

I is He  (Noble Gas)

II is Bo (Group 13)

III is C (Group 14)

IV is Magnesium (Alkali Earth Metal)

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.

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: Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.

Explanation:

Answer:

D has 18 electrons (since atomic number = protons = electrons)  

E has 20 electrons    

Explanation:

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.
