Answer:
Both contain a hydroxyl group on the second carbon.
Neither contain a hydroxyl group on an end chain carbon.
Explanation:
2,2-butanediol Formula: C4H10O2
2,3,4-pentanetriol Formula: C5H12O3
Both contain a hydroxyl group on the second carbon.
Neither contain a hydroxyl group on an end chain carbon.
Exact same conditions as the previous tests. Use the word "variable" instead of conditions though.
Answer: As static charge builds up in a storm cloud, the electric field surrounding the cloud becomes ... plasma and the cloud discharges itself to the Earth through a lightning strike. ... These two mechanisms are believed to be the primary causes of the ... The contact point between ground charge and cloud charge rapidly ascends ...
Explanation:The updraft carries the super-cooled cloud droplets and very small ice crystals ... The differences in the movement of the precipitation cause collisions to occur. ... positively charged and the graupel becomes negatively charged (Figure 2). ... but important positive charge buildup near the bottom of the thunderstorm cloud due ...
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn't.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.
The Clausius-Clapeyron equation:
ln(P₁/P₂) = ΔH/R * (1/T₂ - 1/T₁)
-25 °C = 248 K and pressure is 344 torr
-6.4 °C = 266.6 K and pressure is 760 torr (atmospheric)
Using the equation:
ln(760/344) = ΔH/62.364 * (1/248 - 1/266.6)
ΔH = 175.7 kJ/mol
