Explanation:
Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration. In addition, the majority of transition metals are capable of adopting ions with different charges.
Photosynthesis is very important for our biosphere. Photosynthetic plants convert solar energy into the chemical energy and that stored chemical energy flows into herbivores, predators, parasites, decomposers, and all other forms of life . In the photosynthetic process, light energy is absorbed by the chlorophyll molecules of plants to convert carbon dioxide and water into carbohydrates and oxygen gas. Proteins, fats, nucleic acids, and other compounds also are synthesized during the process.And photosynthesis play important role for maintaining the atmospheric carbon dioxide and oxygen ratio.During the photosynthesis plants absorbs carbon dioxide and release oxygen to atmosphere.All living organisms need oxygen,They cant survive without oxygen.
Answer:
The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. Reaction rates can vary dramatically.
