The right answer is C. I think, a. and d. are obviously not serious. B is not true, because Ag and Au are in the same group in the periodic table and therefore have the same number of electrons in the last level. So, they form ions with the same charge. C is true beacause Ag and Au have different numbers in the periodic table and different amount of protons and neutrons in their nucleuses.

What impacts might you expect on your lifestyle once our society arrives at peak oil? What steps do you think we should take to

irga5000 [103]

Peak oil affects the lifestyle of organisms to a major extent. It is directly to the overproduction of higher levels of toxic compounds when ingested by organisms through air leads to problems like respiratory damage, cancer risk, liver damage, reproductive threat, etc.

Peak oil may be defined as the speculative point in time when the global production of oil acquires its maximum rate.

The steps that should be taken to avoid energy shortages in a post-peak -oil future are as follows:

Increase the dependency on solar energy.
Limit the use of non-renewable sources of energy.
Save major aspects of energy for the future.
Conserve and plant more trees.
Individuals need to make good habits of the utilization of energy-saving components and appliances that consume very less energy.

Therefore, it is well described above.
