Which of the following is most likely to make scientific knowledge stronger?

Chemistry
1 answer:
Mariulka [41]3 years ago
8 0

Answer:

D) Evaluating it with experimentation and argument.

Explanation:

If you don't have enough observational evidence, then you can't really strengthen your scientific knowledge, because you haven't collected enough information to answer the questions you're asking.

If you only have a few scientists working on a question, it will take longer to find an answer. With more people working on a concept, it can be solved in more time.

It can be good to create new hypotheses, but only if you've already tested your original hypothesis (with experimentation and argument), and it turned out to be wrong. Once you've rejected your first hypothesis, only then should you make a new one.

A central atom that is sp3 hybridized could bind up to how many other atoms?
inna [77]

Answer: up to 4 other atoms.

Explanation:

  • <em>Hybridization sp</em>³ means that the atom has 4 equal orbitals formed by the combination of 1 s and 3 p orbitals.

  • Each of these sp³ orbitals is a place for a chemical bonding.

  • Hence, since each orbital is able to bind a different atom, you conclude that <em>a central atom that is sp³ hydridized could bind up to 4 other atoms.</em>

This is precisely the case for carbon (C) atoms.

Carbon has atomic number 6. So its electron configuration is 1s² 2s²p².

The four electrons in the level 2, those shown in 2s² 2p², are in two different orbitals: two are in the orbital 2s and two are in the orbitals 2p.

This diagram shows how those 4 electrons fill the orbitals

  • 2s⇅ 2px↑ 2py↑

The two 2s electrons have lower energy level than the 2px and 2 py electrons, but the difference is not too big.That is why one of the electrons in the 2s ortital can be promoted to the empty 2pz orbital, and you get 4 equal hydridized ortibals, so called sp³.

And that is why, carbon (C) ends up with 4 equal (hydridized) orbitals which can bind up to 4 different atoms, including other carbon atoms, and so, form long chains and, virtually, infinite compounds.

Which of the following scenarios best illustrates the opponent-process theory of color vision?
Kitty [74]

Answer:

Kayla sees afterimages of opposing colors when she stares at a poster for a long time.

Explanation:

The "opponent-process theory" is a theory developed by <em>Edward Hering. </em>It states that<u> three color pairs</u>, which are opposing in nature, are linked by the cone receptors. These pairs are:

  • blue/yellow
  • red/green
  • black/white

This can be done when you stare at an<em> afterimage patch</em> for<u> 30 seconds.</u> Such as what Kayla is doing. Once the color stimuli is removed and she fixates her attention to a dot at the center of her field,<em> she'll notice the colors being reversed</em>. This means that if she sees the original color as<em> "blue,"</em> she'll see it now as <em>"yellow"</em> and<em> vice-versa</em>.

Extended inspection of a color in a pair results to it being <u>fatigued</u>. This allows the<u> non-fatigued color pair to be noticed</u>.

So, this explains the answer.
