The partial pressure of O2 in your lungs varies from 25 mm
Hg to 40 mm Hg. What mass of O2 can dissolve in 1.0L OF water at 25.0oC when
the O2 partial pressure is 40. mm Hg? Since the normal Water solubility of
oxygen at 25oC and pressure = 1 bar is at 40 mg/L water, the partial pressure
is only40 mmg Hg
Mass of 02 dissolve = (40 mmHg/760 mmHg)*( 40 mg/L) (1 L)
=2.10 mg O2 dissolved
<span>another limitation is the span of the human life. assuming that you want to go outside of the solar system, it is much too far to travel for a human.
in addition there is the speed limitation. of course, Einstein predicts that in order to travel at the speed of light, the substance must have no mass. therefore, it is impossible for a human - let alone a spaceship - to travel at that speed, crushing our dreams of interstellar travel (in a human lifespan).

Answer:
yes
Explanation:
because chemical wheathering could wheather it away into a ditch
A chemical symbol designates an element that belongs to the periodic table.
A chemical formula combines two or more symbols and it represents a chemical compound. We notice that the chemical symbols are followed oftenly by a subscript that represents the mole proprtions of next element.
