Calcium has the least attraction for electrons in a chemical bond
Answer:
The greenhouse effect is a phenomenon that occurs when the incoming Solar radiation, which is partially absorbed and partially reflected from the Earth's surface, is then absorbed and re-emitted by the molecules of gas in the atmosphere, causing an increase in the Earth's temperature.
More specifically, the phenomenon occurs as follows:
- The Sun emits electromagnetic radiation in the entire spectrum - therefore, all wavelengths. However, the peak of its radiation is in the visible part of the spectrum, specifically around the yellow color (around 500-600 nm)
- The radiation from the Sun reaches the Earth and passes through the atmosphere, reaching the Earth's surface
- Part of this radiation is absorbed by the surface, while part is re-emitted. However, the radiation is re-emitted at a longer wavelength, in the infrared part of the spectrum (700 - 1000 nm)
- As a result, when this infrared radiation reaches the atmosphere, it is absorbed by the molecules of some gases, which therefore absorbs this radiation and re-emit is in every direction (also towards the surface)
As a result of this radiation emitted by these gases, the Earth's temperature increases.
The dehydration of the CoCl₂ hydrate is as follows:
CoCl₂l•6H₂O(s) + heat --> CoCl₂(s) + 6H₂O(g)
Foxes are warm blooded, so their bodies will cool themselves when they are overheating, Ectothermic animals, in other words cold blooded animals, have to find ways to cool themselves with water or shade, ect.
Answer:
A. Hund's rule has been violated
Explanation:
There must be one electron with the same spin in each orbital of the same energy before you can put two in the same orbital. In the photo, the 2s sublevel is completely filled before the 1s sublevel (if anything the 1s should have an up spin and down spin, with the 2s having one up spin).
