It is an Alkene because it has a double bond, so it’ll have “ene” at the end. The simplest Alkene has 2 carbons.
2 carbons = “eth”
Look at that! Two carbons! It must be “ethene”
Answer:
1.717 J/g °C ( third option)
Explanation:
A piece of the unknown metal dropped into water this means that Q of metal is equal to Q of the water. We write this equality as follows:
<u>Step 1: writing the formulas:</u>
Q = mc∆T
⇒ -Q(metal) = Q(water) Because :Metal dropped into water this means that Q of metal is equal to Q of the water.
<em>We can write the formula different :</em>
Mass of metal * (cmetal)(ΔT) = Mass of water *(cwater) (ΔT)
⇒ Here c is the specific heat and depends on material and phase
<em>For this case :</em>
mass of the metal = 68.6g
mass of the water = 42g
Specific heat of the metal = TO BE DETERMINED
Specific heat of the water = 4.184J/g °C
Initial temperature of the metal = 100 °C ⇒ Change of temperature: 52.1 - 100
Initial temperature of the water = 20°C ⇒ Change of temperature: 52.1 - 20
<u />
<u>Step 2: Calculating specific heat of the metal</u>
-(Mass of metal) * (cmetal)*(ΔT)) = (Mass of water) *(cwater)*(ΔT)
-68.6g (cmetal)(52.1 - 100) = 42g (4.184j/g °C) (52.1 - 20)
-68.6g *cmetal * (-47.9) = 42g (4.184j/g °C) *(32.1)
3285.94 * cmetal = 5640.87
cmetal = 5640.87 / 3285.94 = 1,71667 J/g °C
cMetal = 1.717 J/g °C
<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>
1. its temperature will rise continuously until it melts
I don't believe that any of the other answers are correct because it can not stay at a certain temperature if it is melting
