important nutrients needed by fish in the aquatic
environment to survive.
Which scenarios may be explained by the facts on
the left? Check all that apply.
ID There is more dissolved oxygen in colder
waters than in warm water.
IM
Fact 2: Unlike solids, whose solubility increases
with increasing temperature, the solubility of gases
generally decreases with increasing temperature.
IND
There is less dissolved oxygen in colder
waters than in warm water.
Fish life in the ocean is more abundant during
the seaons with warmer water than seasons
with cooler water
HII
If ocean temperatures rise, then the risk to
the fish population increases.
DONE W
Answer:
A. There is more dissolved oxygen in colder waters than in warm water.
D. If ocean temperature rise, then the risk to the fish population increases.
Explanation:
Conclusion that can be drawn from the two facts stated above:
*Dissolved oxygen is essential nutrient for fish survival in their aquatic habitat.
*Dissolved oxygen would decrease as the temperature of aquatic habit rises, and vice versa.
*Fishes, therefore, would thrive best in colder waters than warmer waters.
The following are scenarios that can be explained by the facts given and conclusions arrived:
A. There is more dissolved oxygen in colder waters than in warm water (solubility of gases decreases with increase in temperature)
D. If ocean temperature rise, then the risk to the fish population increases (fishes will thrive best in colder waters where dissolved oxygen is readily available).

Any type of metal may join with a non-metal, such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium, to create ionic compounds.
A chemical compound known as an ionic compound is one that contains ions bound together by the electrostatic forces known as ionic bonding. Despite having both positively and negatively charged ions, or cations and anions, the molecule is generally neutral.
In most cases, ionic compounds are created between metal and nonmetal components. For instance, the ionic compound calcium chloride is made up of the metal calcium (Ca) and the nonmetal chlorine (Cl) (CaCl2).
A nonmetal and a metal can create an ionic bond, which is the attraction between two ions with opposing charges.
Thus, metal are joined with a non-metal, such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium, to create ionic compounds.

Answer/Explanation:
Aluminum and oxygen
Fluorine and oxygen
Ionic compounds are formed when any type of metal is combined with a non-metal such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium.
(any)metal + nonmetal = ionic compound
Answer: Option (d) is the correct answer.
Explanation:
At high temperature, there will be more collision between the molecules as a result more energy will generate. Thus, a wave can move quickly.
In case of solids, the particles are held more closely with each other. Therefore, when temperature is high then solid particles being closer can pass on the energy more quickly as compared to gases.
Thus, we can conclude that waves move fastest in high-temperature solids.
In Physics, waves move fastest in high-temperature solids due to the close proximity of particles which facilitates faster wave transmission and the increased kinetic energy at high temperatures.
In the study of Physics, the speed of sound waves varies depending on the properties of the medium through which they are traveling. Solids have tightly packed particles which facilitate faster wave transmission. Conversely, gases have loosely packed particles which slow down wave travel. Temperature, while affecting speed at some level, doesn't have as significant an influence as the state of matter itself.
Therefore, among the options you provided: low-temperature gases, low-temperature solids, high-temperature gases, and high-temperature solids, waves move fastest in high-temperature solids.
This is due to the increased kinetic energy of the particles in a high-temperature solid as compared to a low-temperature solid; and the closer proximity of particles in a solid as compared to a gas.
