Answer:
The answer is below
Explanation:
1. With the aid of natural hues, the fox can change its color based on the environment it found itself in. For example, during summer and spring, fox color changes to dark to provide itself cover in the environment that is characterized by the brown dirt. Similarly, the fox color changes to white during winter and fall to blend with the snow.
2. In a bid to domesticate fox, it has been observed over many generations that the domesticated fox compared to wild fox has floppy ears and curly tails. The stress hormone level has reduced significantly and they possess a smaller adrenal gland.
Answer:
Yes
Explanation:
Answer: N (atomic number 7)
Explanation:
1) Due the electron distribution of each, taking into account Hund's rule to deal with pairing of electrons.
2) Hund's rule: each subshell orbital is occupied with single electrons of parallel spin before double occupation occurs.
That is, before any one orbital is doubly occupied, every orbital in a subshell is singly occupied with one electron, and all the electrons in singly occupied orbitals have the same spin, which means that they are unpaired.
3) Distributions:
a) C (atomic number 6) ⇒ 6 electrons:
⇒ 1s² 2s² 2p² ⇒ 1s² 2s² 2p ↑ ↑ : as per Hund's rule the two electrons on 2p are unpaired.
b) O (atomic number 8) ⇒ 8 electrons
⇒ 1s² 2s² 2p⁴ ⇒ 1s² 2s² 2p⇅ ↑ ↑: as per Hund's rule the two 2p electrons are unpaired
c) N (atomic number 7) ⇒ 7 electrons
1s² 2s² 2p³ ⇒ 1s² 2s² 2p↑ ↑ ↑: as per Hund's rule, the three 2p electrons are unpaired, so this is the answer to the question.
c) Be (atomic number 4) ⇒ 4 electrons
⇒ 1s² 2s² ⇒ none p electron.
Nitrogen has three unpaired electrons in its p orbital.
Among the given elements, nitrogen (atomic number 7) has three unpaired electrons in its p orbital.
In the electron configuration of nitrogen, it has a total of five electrons: 2 in the 1st energy level and 3 in the 2nd energy level. The p sublevel of the 2nd energy level contains three orbitals, each capable of holding 2 electrons. Therefore, the three unpaired electrons in nitrogen's p orbital are in three separate p orbitals in the 2nd energy level.
Carbon has two unpaired electrons in its p orbital, while oxygen has two unpaired electrons in its p orbital and two in its s orbital. Beryllium does not have any unpaired electrons in its p orbital.

(3) determine the freezing point of the mixture
(4) predict the electrical conductivity of the mixture
Answer:The correct answer is option (1).
Explanation:
Density is defined as mass of substance present in the unit volume of the substance.
Density can be used to separate two substance from their mixture. Substance with lower density will place itself on the top of the substance with higher density, And in order to distinguish those two substance from each other one can easily observe the boundary among those substance.
2) If the substance is a liquid, a change of some of the liquid to gaseous form would indicate a chemical change.
3) If the substance is a solid, a change of some of the solid to liquid form would indicate a chemical change.
4) If the substance is a liquid or solid, the production of an odor would indicate a chemical change.

b. chloride
c. sulfates
d. calcium
Answer:
Explanation:
a five step process that scientists use when they do their work.
1. ask a question
2. form a (testable) hypothesis or educated guess
3. conduct a controlled experiment (to test the hypothesis)
4. record & analyze results
5. develop a conclusion --> use the data from the experiment to see if it supports your hypothesis
