The _HIGHER__ vapor pressure at high altitudes causes a liquid to boil at a _LOWER___ temperature.
Explanation:
Vapor pressure is the pressure applied by the molecule of a liquid at the surface of the liquid as it transitions into a gaseous phase. When the vapor pressure exceeds the atmospheric pressure, this is when the liquid begins to boil. Therefore when the atmospheric pressure is low, then the liquid will boil at lower temperatures, because the vapor pressure of the liquid will overcome the atmospheric pressure at lower temperatures.
Answer:Charge on X = (+ 2)
Explanation:
Charge on one Cl = -1
So Charge on two Cl = -2
The molecule = Neutral = 0 charge
So, to make total charge = 0 , the X should have +2 charge
XCl2 = +2 -2 = 0
X = +2
Alkaline earth metals(Be , Mg , Ca , Sr) form such type of compounds
Explanation:
<span>From Graham's law of diffusion.
Rate of diffusion of Neon/Rate of diffusion of Bromine =âš(Molar mass of bromine gas/Molar mass of Neon) Molar mass of bromine gas =79.904 and Molar mass of Neon = 20.17. So we have. âš(79.904/20.17) from the right hand side of the equation. Hence it follows that.
Rate of diffusion of Neon/Rate of diffusion of Bromine = âš3.96 = 1.98. Hence it follows that Rate of Diffusion of Neon is 1.98 or (2 times, to1d.p) the rate of diffusion of Bromine.</span>
Answer:
solid, liquid and then gas where it melts and then evaporates or directly by sublimation
If I understand you correctly, then this is the equation for the breakdown of monosaccharide.
monosaccharide --> Carbon dioxide + water
