1.Some earthquakes are associated with volcanoes. A lot of earthquakes are alongside the rims of tectonic plates. This is in which some volcanoes are too.
2. Earth changes in its personal ways. Some changes are because of gradual processes, consisting of erosion and weathering, and a few changes are because of fast processes, consisting of landslides, volcanic eruptions, Tsunamis and earthquakes. Waves, wind, water, and ice form and reshape the Earth's land surface through eroding rock in a few regions and depositing them in different regions, now and again in seasonal layers. Tectonic plates drift, the crust quakes, and volcanoes erupt. All of these effective forces form our air, land, water, and climate and are constantly reworking our planet.
Answer:
Answer
The limitations are-
1. Privacy of the individuals involved in the research process.
2. Physical and psychological risks should be minimized
3. The subjects should be chosen equitably
4. Only reasonable exposure to risks is admissible.
Explanation
The privacy of the individuals involved in the research must be taken into consideration. This will ensure safety of patient data and information. The risk of physical and physiological well being of the person must be taken into consideration in such a research. In addition to that, the subject must be made to understand every procedure and the risks involved before testing. Moreover, only minimal exposure to risks is allowed and must have been previously tested in animals to avoid deaths.
Each atom/element has an electron configuration
The electron configuration shows the energy level of the electron
Each electron configuration has 4 quantum numbers, namely n, l, ml, and ms
- n = the principal
- l = the angular momentum / azimuthal
- ml = the magnetic
- ms = the electron-spin
We make an example of the element Mg which is in group 2 with the atomic number 12
Electron configuration of Mg: [Ne] 3s² or 1s² 2s² 2p⁶ 3s²
if Mg removes 2 electrons then Mg will form a positive ion (cation) Mg²⁺
This cation is included in the monatomic ion because it is formed from one element (in contrast to the polyatomic ion, which is formed from two or more elements such as SO₄²⁻, ClO₃⁻)
Electron configuration of Mg²⁺ : 1s² 2s² 2p⁶
So atoms can be positively or negatively charged depending on removing or attracting electrons
FeO is Iron II Oxide. You identify that it's an ionic bond so it won't have any prefixes. By reverse criss-crossing the charges, Iron gets a 1+ charge, and Oxygen gets a 1- charge. Since you know that Oxygen has to have a 2- charge, you multiply the 1+ and 1- by 2 to fix their charges, thus giving Iron a 2+ charge and Oxygen a 2- charge.
Since Iron has a 2+ charge, it's roman numeral is II. So the answer is Iron II Oxide.
The other one is Iron III Oxide. By reverse criss-crossing the charges, Fe geta 3+ charge, and Oxygen gets a 2- charge. Since it's correct, the 3+ charge is the roman numeral. So, the answer is Iron III Oxide.
