First look at the H (that is hydrogen) in the formula. There are 3. This would be right, but notice the 3 at the beginning of the formula. This coefficient tells you to multiply all values by 3. So you multiply the 3 hydrogen atoms by 3, which is 9.

Answer is C: 9

The answer is C.

While the Hydrogen atom symbol itself is labeled with 3, it is being multiplied by the coefficient of 3, giving us a total of 9 atoms.

What cultural differences does Herodotus notice between Greek ways of living and those of Persia and Egypt
Sindrei [870]
<span>The Persian Wars mark an important turning point not only in Greek history but, indeed, in the course of all European civilization. First and foremost, because of its victory Greece was saved from the threat of external rule and could develop on its own. Handed this independence, the Greeks chose to follow a path which forever changed the course of modern life. Without their success in this conflict, they would, no doubt, never have had the liberty, means or conviction to invent, discover or create all they did: not just history but philosophy, science, drama, art, architecture, indeed most of the cornerstones of modern civilization. Another consequence of this victory, less immediate but equally important, was that it prevented the Persians from dominating the lands to the west of Greece—as noted above, it's likely the fertile fields of Italy and Sicily, not the rough dust of Greece, were the real target of Xerxes' imperial designs—and there a tiny settlement called Rome had just begun to sprout, at that moment hardly a dot on the map, but it would later develop into a crucial player in the history of the West. Rome won freedom, too, in the Persian Wars, without ever fielding a single fighter. It's impossible to imagine how vastly different our world would be if Persia had conquered or exterminated the Romans before they'd ever had a chance to grow. Thus, the Greeks laid the groundwork for later Western culture, and Herodotus the foundation for understanding it. If so many of his facts look suspect or even prove incorrect, if he sometimes seems to set speculation and scandal over sober criticism and science, before condemning him we should recall that he founded this entire enterprise called history, a discipline which still bears the name he gave it. His critics should also bear in mind it's only because Herodotus set us on this path that we can even scorn his methods in the first place. To this most uncommon "common man," we owe an enormous collective debt.</span>

trasher [3.6K]

What's wrong with this setup is the substrate on which you have positioned the drop is "dirty and unclean" meaning it is not being dampened by the solution. This action can be corrected by comprehensively cleaning the substrate where the drop will be positioned.
