Answer:
For the process of gold mining , Na₂CO₃ is better than Fe₂O₃
Explanation:
<u>The task of a gold miner , is to extract gold .</u>
For the process of Gold mining , carbon filters are preferred , because by using carbon filters gold can be easily extracted .
In general , silver and gold get adsorbed on the surface of carbon , hence can be very conveniently extracted from the solution .
Answer:
It will increase because warm air rises up and cold air drops

Answer:
Explanation:
Scattering of solar radiation within the atmosphere also accounts for a reduction of energy reaching Earth. Atmospheric gas molecules and aerosols deflect solar radiation from its original path, scattering (reflecting) some radiation back into deep space and some toward Earth's surface.
Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.
A Quick Overview of Light Absorption
In absorption, the frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state.
