Answer:
Most metals have <u>luster</u> which means they <u>reflect</u> light
Explanation:
When light, which is made up of energetic photons, comes in contact with the surface of a metal, it is absorbed due to the corresponding energy gaps present between the metal orbital. The absorbed photons results in the raising of the energy levels of electrons within an atom of the metal which later drop back to a lower energy level and re-emit the photons which can now be observed as the metallic luster.
Answer:
0.34
Explanation:
Cu>>>Cu2+(oxidation number increases)[Oxidation occurs]
Ag+>>>Ag(Oxidation number decreases) [Reduction occurs]
E°=0.80-0.46
=0.34V
Answer: The three end products of the oxidation-reduction reactions involved in metabolism are WATER, CARBON DIOXIDE and ATP.
Metabolism refers to the sum of all chemical reactions occurring in the body. It includes both catabolism and anabolism. Every metabolic reaction is characterized by oxidation-reduction reactions. The metabolic pathways include respiration, photosynthesis, etc. In all these reactions water is produced. In respiration CO2 is also a product. In general. in every metabolic reaction either an organic molecule is broken or synthesized producing CO2, water and energy.
