Some transition metals form more than one type of ion. How are these ions distinguished from one another in writing formulas for compounds?
using Roman numerals
using Latin prefixes
using numerical superscripts
using Arabic numerals
HELP!!!!!!!!!!!!!
Answer:
Using Roman numerals
Explanation:
Distinguishing between the ions of a transition metal in writing involves the use of roman numerals.
A popular case to look at is the element iron.
There are two popular ions of iron. These are the iron 2 and the iron 3 ions
While they differ physically, they can also be differentiation writing.
Iron 3 is written as Fe3+ While Iron 2 is written as Fe2+
Thus, we can write their tetraoxosulphates vi salt name as follows;
For iron ii, we have iron (ii) textraoxosulphate vi while for iron iii, we have iron (iii) tetraoxosulphate vi.
Thus, the use of the roman numerals has helped us in distinguishing between the two types of ions of the same iron

Proper nutrition is needed to be a healthy person. Track how many calories you eat and how many calories you burn in a day. Select the Calorie Tracker to get started. Use the rubric to guide you.
(ion know how to keep track of calories and i hate try to do it so just make up some paragraph for me for this assignment please.)
Here, I hated PE too. Write down calories, and make up lame exercises to "burn them off" like running or swimming or dancing. Do it appropriately, sometimes you can't allways burn it off, like if you gained 100 calories and only burned 80. It's fine.
A rule of thumb is that about 100 calories per mile are burned for a 180-pound person and 65 calories per mile are burned for a 120-pound person. A 150-pound person will burn roughly 400 calories during an hour-long swim at a moderate pace and 700 at a vigorous one. The average person will burn 300-800 calories per hour dancing.

Which of the following forces has not changed Earth's surface?
folding
erosion
weathering
gravity
Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

“That's right,” said the Queen, patting her on the head, which Alice didn't like at all, “though, when you say ‘garden,’—I'VE seen gardens, compared with which this would be a wilderness.”
Alice didn't dare to argue the point, but went on: “—and I thought I'd try and find my way to the top of that hill—”
“When you say ‘hill,’” the Queen interrupted, “I could show you hills, in comparison with which you'd call that a valley.”
“No, I shouldn't,” said Alice, surprised into contradicting her at last: “a hill CAN'T be a valley, you know. That would be nonsense—”
The Red Queen shook her head, “You may call it ‘nonsense’ if you like,” she said, “but I'VE heard nonsense, compared with which that would be as sensible as a dictionary!”

Where would you expect a hot main-sequence star with high luminosity to be located on the following HR diagram?
Hertzsprung-Russell Diagram
The Hertzsprung-Russell diagram (HR diagram) is one of the most important tools in the study of stellar evolution. Developed independently in the early 1900s by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the colour of stars (or spectral type) against their absolute magnitude (the observational HR diagram, also known as a colour-magnitude diagram).
Depending on its initial mass, every star goes through specific evolutionary stages dictated by its internal structure and how it produces energy. Each of these stages corresponds to a change in the temperature and luminosity of the star, which can be seen to move to different regions on the HR diagram as it evolves. This reveals the true power of the HR diagram – astronomers can know a star’s internal structure and evolutionary stage simply by determining its position in the diagram.

What information is used to determine earthquake risk?
Answer:
There are several pieces of information that are used to determine earthquake risk:
Seismic data: This includes information about the frequency, size, and location of earthquakes that have occurred in a particular area. This can help scientists understand the likelihood of future earthquakes and how strong they are likely to be.
Geological data: This includes information about the geology of an area, including the types of rocks and soil present, the structure of the Earth's crust, and the presence of fault lines or other features that may affect the likelihood of earthquakes.
Population data: The number of people living in an area can also be a factor in determining earthquake risk, as a larger population is more likely to be affected by an earthquake than a smaller one.
Building data: Information about the types and condition of buildings in an area can also be used to determine earthquake risk, as buildings that are poorly constructed or not designed to withstand earthquakes are more likely to be damaged or collapse.
Insurance data: Insurance companies may also use data about past earthquakes and their effects to help assess the risk of future earthquakes in an area.
Overall, the risk of earthquakes is determined by a combination of these and other factors, and it can vary significantly from one location to another.
Answer:
In order to determine earthquake risk, information on the density of buildings and people (exposure), the vulnerability of the built environment, and robust earthquake hazard assessments, including the impact of local soil conditions, are needed.
Students are investigating the rocks with fossil markings that are found in an area that was once covered by a lake. The rocks they are observing are MOST likely —
igneous
metamorphic
sedimentary
thermic
Answer:
sedimentary rock
Explanation:
The rocks they are observing are MOST likely sedimentary. The correct option is C.
What is sedimentary rock?Sedimentary rock is one of the three main types of rock formed on Earth (the others being igneous and metamorphic rocks). It is formed by the accumulation and solidification of sediment, which is any material that is transported by wind, water, or ice, and eventually deposited on the Earth's surface. This can include particles of minerals, rocks, and organic matter.
Over time, these sediments are buried and subjected to pressure and compaction, which causes them to become more tightly packed and solidified. The weight of the overlying layers can also cause the sediment to undergo cementation, where minerals dissolved in water between the particles precipitate and bind them together. As the sediment becomes more compacted and cemented, it eventually becomes a solid rock.
Sedimentary rocks are often characterized by their visible layers or strata, which can contain fossils and provide a record of past environmental conditions. They are also important sources of natural resources, such as coal, oil, and natural gas, as well as many of the minerals and building materials used in construction. Some common examples of sedimentary rocks include sandstone, shale, and limestone.
Here in the question,
Sedimentary rocks are formed from the accumulation and consolidation of sediment, often containing fossils. The fact that the area was once covered by a lake supports the idea that the rocks would have been formed from sediment deposited in the lake. Therefore, option C is the most likely and correct choice.
Igneous rocks are formed from molten magma and do not typically contain fossils. Therefore, option A is not correct.
Metamorphic rocks are formed from preexisting rocks that are altered by heat and pressure. They also typically do not contain fossils. Therefore, option B is not correct.
Thermic is not a commonly used term in geology, so option D is not a valid choice.
Therefore, The correct option is C. sedimentary.
