No. you were right, the bond angle makes it polar.
That’s it.
Go with it.
104.5 degrees is the angle for the hydrogens coming off from the central atom of oxygen in the water molecule. Not the hydrogen bonding going on between molecules
Water is considered a polar molecule
Correct. that was what i was referring to...
Yep, water is an interesting molecule.
yes, i believe that is correct, i mistyped earlier. like i said, my memory of my chem days is fading.
PV=nRT ?

Correct. I like [P = ρRT]. Fun with the equation of state:
So, we have the 1st law of thermodynamics,
[dQ = Cp(dT) - dP/ρ],
and, the equation of state, [P = ρRT].
Now, ρ = P/RT, substitute into 1st law of thermodynamics.
dQ = Cp(dT) - RTdP/P.
Set dQ = 0, no change in internal heat from condensation.
Now, Cp(dT) - RT(dP/P) = 0.
Or, Cp(dT/T) = R(dP/P). Integrate both sides,
Cp∫(dT/T) = R∫(dP/P). After integration,
(Cp/R) ln(T) limit: |To-θ = ln(P) limit: |Po-P(1013).
Now, ρ = P/RT, and dP/dz = -ρg (hydrostatic equation).
dP/dz = -Pg/RT, hold temperature T constant.
dP/P = -g(dz)/RT, integrate,
ln(P0/P1) = -gz/RT, exponentiate both sides,
P0 = P1•exp(-gz/RT).
Water consists of polar molecules.
Oceans absorb CO2 when the climate cools and releases CO2 when the climate warms. The fall/rise in atmospheric CO2 always lags the fall/rise in global temperatures.
Shocker! Coca cola, set out in the sun, foams in your mouth!
Does nobody work in the heat anymore?
Duh..sy-ense!
Are we really as dumb as 2nd graders?
Apparently so.
I Wonder, How much did we spend on this Government Study?
