Answer:
The correct option is;
Is found near bodies of water
Explanation:
Fog forms as an aerosol which is visible to the eye that normally consists of tiny condensed water vapor droplets or crystals of ice that is formed when air that is warm comes in contact with cool air close to the Earth's surface. Fog can be taken as a stratus like cloud that lies close to the Earth's surface and it normally forms due to the presence of water bodies that are nearby, the topography of the area or the conditions of the wind.

A new scam on the Internet involves people selling samples of sodium that they collected from a secret river in the mountains. Write a short statement to explain why this is a scam.
Answer:
Explanation:
The reason this is a scam is because they are selling sodium and to sell this product you must have a licence to do so. And secondly, you cant tell the reader that it is from a secret river and sell them a product that reacts when it touches water.
Sodium is a very highly reactive metal that does not occur in free state in nature.
Sodium is a group 1 element. It has a very negative electrode potential which implies that it is highly reactive. Being a highly reactive element, sodium can not occur in free state in nature. It always occurs in combined form as compounds.
Hence, it is impossible to pick up sodium from any secret river in the mountains. Sodium metal is highly reactive hence it has to be stored under paraffin oil. The whole set up is indeed a scam.

(a) hypothesis
(b) controlled experiment
(c) theory
(d) research plan
Answer:
theory
Explanation:
In the scientific method, every scientific investigation begins with observation. After observing the phenomenon, the researcher puts out an intelligent guess that explains his/her observation. This intelligent guess is known as a hypothesis.
This hypothesis is now subjected to carefully designed experiments which may prove or disprove the hypothesis. If the results of the study is well received among the scientific community, the hypothesis becomes a theory.
Hence, a well-accepted body of knowledge about any subject of study in science is an example of a theory.

give at least five insights that you learn from this lesson, as your way of recognizing the uniqueness of earth as a planet life
Answer and Explanation:
The lesson about the uniqueness of the earth allowed me to realize that the earth is the only planet that has drinking water and oxygen, thus allowing the existence of life on the planet and showing that we would not fully survive on another planet.
The lesson also shows that the earth is the only planet where rotation is capable of causing seasonal differences in different parts of the globe. This is important for several things, including food production and plant growth.
Another factor that shows the uniqueness of the land is its favorable temperature for life, allowing us to have water and to be able to live outdoors, for example. This factor is worrying, since the holes in the ozone layer have caused changes in this temperature.
I was also able to learn about the gravity of the earth, which is the only thing that allows us to do all the activities we do and allows us not to be launched into space. In addition, gravity has a strong influence on seas and agriculture.
Finally, I was able to learn about the tectonic plates, which provide the movement of our crust and influence in several geological processes.

What if you broke off a piece of cement (or bread) so that it was only half the volume of the original piece? What would happen to
the mass?
Answer:
The mass is also half of the mass of the original piece
Explanation:
Recall that the volume of a substance is defined as mass/volume. The density of substances is a constant. Hence, if a break off a piece of cement or bread such that what remains is only half the volume of the original piece, the mass of the new piece must also reduce to half of the mass of the original piece so that the volume of the material will remain constant.
Hence the answer above.
A balloon has a volume of 6.25 L at 453 kPa. What would the volume of this balloon be at 325 kPa?
Answer:
4.48 L
Explanation:
P1/V1 = P2/V2
453/6.25 = 325/ x
453x = 6.25*325
x = (6.25*325)/453
x = 4.48 L
Describe the relationship between a boiling point and hydrogen bonds in a substance.
Hydrogen bonding between molecules(inter mlecular) is one such attractive force. ... In water because of the hydrogen bonding attraction between molecules greater energy is needed to separate them from against their inter molecular attraction, therefore higher boiling point.
The boiling points of molecules with hydrogen bonds will always be higher than those of molecules of similar size without an -O-H or -N-H group.
What is hydrogen bonding ?
When a hydrogen atom bonded to a strongly electronegative atom is in close proximity to another electronegative atom with a single pair of electrons, the hydrogen bond is an intermolecular force (IMF) that results in a unique type of dipole-dipole attraction. There are forces between molecules called IMFs. Dipole-dipole interactions and dispersion forces are two additional examples. While true covalent and ionic bonds are stronger than hydrogen bonds, dipole-dipole and dispersion forces are generally weaker.An organic molecule with an -OH group is called an alcohol. Hydrogen bonds can occur in any molecule that has a hydrogen atom directly attached to an oxygen or nitrogen. When hydrogen is bonded to fluorine, hydrogen bonds also occur, but other molecules lack the HF group. The molecules become as a result of the hydrogen bonding, requiring more heat (energy) to separate. The boiling point of various molecules, which is the temperature at which a phase change from liquid to gas takes place, can be examined using this phenomenon.The ethanol's hydrogen bonding has raised its boiling point by about 100°C. It is essential to comprehend that van der Waals attractions are not the only forms of hydrogen bonding. For instance, each of the molecules that follow has the same number of electrons, and the two that follow have chain lengths that are comparable. Because of the additional hydrogen bonds, the butan-1-ol has a higher boiling point.To know more about hydrogen bonding check this:

Write the products of these double-replacement reaction. Then balance each equation. a) NaOH(aq) + Fe(NO3)3 (aq)---> Iron (III) hydroxide is a precipitate
Answer:
3NaOH (aq) + Fe(NO₃)₃ (aq) → Fe(OH)₃ (s) + 3NaNO₃ (aq)
Explanation:
Step 1: RxN
NaOH (aq) + Fe(NO₃)₃ (aq) → Fe(OH)₃ (s) + NaNO₃ (aq)
Step 2: Balance RxN
We need 3 OH's on both sides.
We also need 3 NO₃'s on both side.
This will make it so we also need 3 Na's on both side3NaOH (aq) + Fe(NO₃)₃ (aq) → Fe(OH)₃ (s) + 3NaNO₃ (aq)

Is there a common pattern for valence electrons on the periodic table
Answer:
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
Explanation:
what element is found in group 6 and period 4? Based on its location, is the element more similar to tungsten or to iron?
the asnwer is berlinuim become a power geek like me plz itl help u
In a periodic table, there are seven periods and eighteen groups. The element found in group 6 and period 4 is similar to Tungsten.
