Yup

Hhhhhhhh

Thermodynamics and physical chemistry are both same subjects but the work done signs are just opposite.

An answer to your question is that W is already considered negative due to the Work of expansion equation, W = -PexΔV

the answer for delta U was -3263kj/mol . what i got using this, delta U= -3267kj/mol - (6-7.5)(8.314)(298.15) = 451kj/mol

q is not zero But change in q is zero

is the the delta-H-not supposed to be multiplied by 1 mole, since the product is 1 mole of waters, so the units for the answer is in 'kJ'?

+Andrew Nguyenba hey Andrew! Thanks for pointing this out, I think I missed emphasizing a point in my discussion. In thermochemical equations, the delta-H-not is in kJ per mole of balanced reaction as written or (kJ / mol reaction). When we check out the units for the PV work term (delta-n)RT, delta-n is actually change of moles of gas per mole reaction or (change mol gas / mol reaction). What cancels out when multiplying delta-n with R is (mol gas), so the (mol reaction) unit remains. The units for the PV term should be (kJ / mol reaction), same as delta-H-not. I hope this clarifies things!

@@SarahMaySibugTorres There is also a 4th law of thermodynamics as entropy is dual! From a converging, convex or syntropic perspective everything looks divergent, concave or entropic -- the 2nd law of thermodynamics. All observers have a localized, focused or syntropic perspective. Mind (the internal soul, syntropy) is dual to matter (the external soul, entropy) -- Descartes or Plato's divided line. My syntropy is your entropy and your syntropy is my entropy -- duality. Syntropy (prediction) is dual to increasing entropy -- the 4th law of thermodynamics. Teleological physics (syntropy) is dual to non-teleological physics (entropy). Ellipsoids are dual to hyperboloids -- linear algebra & matrices, Gilbert Strang. Positive curvature is dual to negative curvature -- Gauss, Riemann geometry. Curvature or gravitation is dual -- gravitational energy is dual. There are patterns of duality hardwired into physics, mathematics & philosophy. Homology is dual to co-homology. Integration is dual to differentiation. Homology and integration reduce the number of dimensions or states -- a syntropic process. Co-homology and differentiation increase the number of dimensions or states -- an entropic process. Syntropy (convergent) is dual to increasing entropy (divergent) -- the 4th law of thermodynamics. Gaussian negative curvature is defined by at least two points -- non null homotopic. The big bang is a negative curvature singularity or a white hole -- Janus hole/point. Janus holes/points have two faces (duality) -- Julian Barbour, physicist. Points are dual to lines -- the principle of duality in geometry. Null homotopic is dual to non null homotopic. Topological holes cannot be shrunk down to zero -- non null homotopic. The "bridge" between elliptic curves & modular forms is duality! Injective is dual to surjective synthesizes bijective or isomorphism. Thesis is dual to anti-thesis leads to the converging thesis or synthesis -- the time independent Hegelian dialectic. Isomorphism is duality: two differing descriptions or aspects of the same thing. Gravitation is equivalent or dual (isomorphic) to acceleration -- Einstein's happiest thought, the principle of equivalence (duality). "Always two there are" -- Yoda. Duality is hardwired into the laws of physics & mathematics!

thats pretty much all I herd!

i just started the video and I'm genuinely pissed
