Molecular formula of Isoflurane is <span><span>C</span></span>₃H₂ClF₅O.
Now calculate
the percent composition by mass, which means percent of each element in the
compound.
Mass of Isoflurane
= 184.49 g/mol
Mass of carbon in the compound = 3 x
12.011 = 36.033g
Mass of hydrogen in the compound = 2 x
1.008 = 2.016g
Mass of chlorine in the compound = 1 x 35.453
= 35.453 g
Mass of fluorine in the compound = 5 x 18.998
= 94.99g
Mass of Oxygen in the compound = 1 x 16
= 16 g
Carbon’s percentage = Mass of carbon in
the compound /mass of isoflurane x 100 =36.033/184.49 x 100 =19.53%
Hydrogen’s Percentage = Mass of hydrogen
in the compound/mass of isoflurane x 100 = 2.016/184.49 = 1.09%
Chlorine’s percentage = Mass of chlorine
in the compound/mass of isoflurane x 100 = 35.453/184.49 =19.22%
Flourine’s percentage = Mass of fluorine
in the compound/mass of isoflurane x 100 = 94.99/184.49 x 100 = 51.49%
Oxygen’s percentage = Mass of Oxygen in
the compound/mass of isoflurane x 100 =16/184.49 x 100 = 8.67%

Answer: Most of the stars in the universe are main sequence stars — those converting hydrogen into helium via nuclear fusion. A main sequence star may have a mass between a third to eight times that of the sun and eventually burn through the hydrogen in its core. Over its life, the outward pressure of fusion has balanced against the inward pressure of gravity. Once the fusion stops, gravity takes the lead and compresses the star smaller and tighter.
Temperatures increase with the contraction, eventually reaching levels where helium is able to fuse into carbon. Depending on the mass of the star, the helium burning might be gradual or might begin with an explosive flash.
Answer:
Outside air
Nose
Lungs
Bloodstream
Cell
Explanation:
We breathe in oxygen from the outside air in through our nose and it travels to our lungs. Inside our lungs, we have Avioli's that diffuse oxygen into our bloodstream and the bloodstream helps the oxygen travel into our cells.
Hope this helps :)
Answer:
In the explanation
Explanation:
Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.
Convergent: When two plates are moving towards each other.
If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.
If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.
Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.
Hope this helps!
