Answer:
A)provide a basis for virtually all modern anaesthetic techniques
restore tissue oxygen tension by improving oxygen availability in a wide range of conditions such as COPD, cyanosis, shock, severe hemorrhage, carbon monoxide poisoning, major trauma, cardiac/respiratory arrest
aid resuscitation
provide life support for artificially ventilated patients
aid cardiovascular stability
B)Pure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material (e.g. steel) in a room environment. ... Welding metal results when two pieces are heated to a temperature that produces a shared pool of molten metal.
D. They're the main site of photosynthesis in autotrophs.
The equation for percent yield is
As such, the theoretical yield or expected yield is, in this case, 122.7g of Pb, the actual in this case is 107.9g so we have
Therefore, the percent yield of her reaction is 89.94%
