Answers

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.

Explain how CMB is observed on the Earth?

Answers

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!

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

Answers

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 for c plsssssss

Answers

Answer:

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

[Ne]3s² 3p⁶   (spdf electron configuration)2, 8, 8             (basic electron configuration) Argon            

E has 20 electrons    

[Ar]4s²         (spdf electron configuration)2, 8, 8, 2      (basic electron configuration)Calcium

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.

True or false: There is space between molecules in a mixture

Answers

There is always space between molecules to the answer is True.

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

What is a mixture?

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.
