Answer:
exothermic entropy is increased
Explanation:
An exothermic process is one whose rate increases when the temperature is decreased. Hence if a decrease in temperature favours the dissolution of more solute at equilibrium, then the process is exothermic.
Similarly, the dissolution of a solute in a solvent increases the disorderliness (entropy) of the system because of the increase in the number of particles present. Hence once a solute in dissolved, the entropy of the system increases.
Answer:
B.)dissolve more solute than you should be able to.
I hope this helps sorry if it doesn't
Answer: The correct answer is option D.
Explanation:
Mercury is occurs in earth crust but its mining ,combustion of fossil fuel and extraction had led to spreading of mercury pollution not only on lands but in air and water bodies also.
Mercury settled on land get washed way into water bodies which further gets introduced in life process of living beings in the water and eventually effecting the whole food chain or web.
Hence, from the the given options the correct option is (D).
The answer is it tends to be more negative down a group. This is because as you go down the periodic table, the elements have more electron shells in their atoms. This makes the outermost shells less attracted to the nucleus due to their greater distances from the nucleus. Therefore, these shells are less likely to attract electrons (hence lower electron affinity) and are even more likely to lose electrons from their outer electron orbits.
