Halogens (atoms with 7 valence electrons) and Hydrogen
or generally, atoms with their shells almost full
TRUE its glucose if they have sunlight
Answer: Option (d) is the correct answer.
Explanation:
In water cycle, water from clouds fall in the form of rain, snow etc. This water travels through the surface of mountains and passes through rivers, oceans etc and gets evaporated due to heat from Sun.
When water evaporates then it absorbs energy in the form of heat from Sun and when water condenses then heat is released.
Therefore, water gains energy during evaporation and releases it during condensation.
Answer:
The ΔG° is 29 kJ and the reaction is favored towards reactant.
Explanation:
Based on the given information, the ΔH°rxn or enthalpy change is 41.2 kJ, the ΔS°rxn or change in entropy is 42.1 J/K or 42.1 * 10⁻³ kJ/K. The temperature given is 289 K. Now the Gibbs Free energy change can be calculated by using the formula,
ΔG° = ΔH°rxn - TΔS°rxn
= 41.2 kJ - 289 K × 42.1 × 10⁻³ kJ/K
= 41.2 kJ - 12.2 kJ
= 29 kJ
As ΔG° of the reaction is positive, therefore, the reaction is favored towards reactant.
