The correct answer is A. Urban areas have higher temperatures.
Explanation
Urban Area is a term to refer to cities. Urban areas are characterized by having a developed infrastructure (wide roads, vehicular bridges, wide platforms, tall buildings, residential areas, industrial areas, among others).
Recent studies affirm that urban areas are warmer than surrounding areas; This phenomenon is because the materials with are built buildings, roads, houses, and others, concentrate the sun's rays, increasing the temperature of cities. In addition, the lack of trees deepens this phenomenon, because the trees contribute to cooling by physicochemical processes such as evapotranspiration.
According to the above, it is possible to affirm that urban areas are hotter than their surrounding area because they lack vegetation, and the materials with which it is built contribute to the increase in temperature.
On the other hand, urban areas are characterized by habitat fragmentation, more problems with soil erosion, and less rain infiltration into the soil.

Okay Elements can combine to created element compounds a few examples can be lets say Gold(Au) Is an example of an Iconic Compound (usually a common compound). An Element Mixture is literal a mixture Ex. Brass. Brass is usually 10% copper and 45% zinc. So in order to get Brass you must physically m<span />ix copper with zinc and the other metal (sorry i don't remember the name) Also mixtures tend to not be chemically constant, this is because it was physically mixed rather than all of the atoms be the same if they were chemically combined.
Answer:
When there are too many protons, some of the outer protons are loosely bound and more free to react with the electron. But most atoms do not have too many protons, so there is nothing for the electron to interact with. As a result, each electron in a stable atom remains in its spread-out wavefunction shape.
In an atom, there is a nucleus made up of neutral charged, neutrons, and positively charged protons. The reason why electrons which are negatively charged, don't fly off is due to its stronger attraction to the protons. ... This, however, still allows the electrons to move around the nucleus of an atom.
Answer: sorry can't help ya
Explanation:
Sorry it's just I don't really know how to answer this question myself wish you the best of luck ;3
Answer:
A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.
Explanation:
- In nuclear reactions there arises a shift in the nucleus of the atom. This results in the production of a different element altogether. While in chemical reactions the electrons are rearrangement and there is no change in the nucleus.
- Factors like temperature, pressure, and catalysts do not affect the rate of nuclear reactions while they influence the chemical reactions.
- The change in the energy is higher in nuclear reactions. It arises out of the destruction of mass.
