Group.... because elements in a group have same chemical properties
Answer:
The solar energy is converted to chemical energy by the process of photosynthesis - This is the true statement of the given question.
Explanation:
An ecosystem usually refers to the biological community comprising all the types of living species that are continuously interacting with the surrounding environment. Most of these ecosystems are solar-powered, and by this phrase, it means that there occurs the transformation of energy from solar to chemical energy which is taking place due to the process of photosynthesis. Both the terrestrial and the aquatic, are able to carry out this process in the presence of sunlight, water, and CO₂, and in return, it liberates food and oxygen into the ecosystem.
Thus, this statement satisfies the given phrase.
All other options are false as it does not justify the phrase.
There are TWO atoms in one molecule of hydrogen.
Answer: It means that the energy is being stored or preserved to be used at a later time.
Your question was a little vague, so if this isn't the answer you were looking for, just let me know and I'll fix it.
Hope this helps! Good luck! :D
Answer:
ΔG=ΔG0+RTlnQ where Q is the ratio of concentrations (or activities) of the products divided by the reactants. Under standard conditions Q=1 and ΔG=ΔG0 . Under equilibrium conditions, Q=K and ΔG=0 so ΔG0=−RTlnK . Then calculate the ΔH and ΔS for the reaction and the rest of the procedure is unchanged.
