Answer:
<u><em>Pangaea</em></u>
<u><em>Alfred Wegner</em></u>
<u><em>plate tectonics</em></u>
Explanation:
What did Earth look like 250 million years ago? The continents of Earth were clustered together in formation that a scientist named<em> </em><u>Pangaea</u><u><em>.</em></u>The scientist that named "Pangaea" was a German scientist by the name of <u>Alfred Wegner.</u> He theorized that "Pangaea" split apart and the different landmasses, or continents, drifted to their current locations on the globe. Wegener's theories of plate movement became the basis for the development of the theory of <u>plate tectonics.</u>
Use this equation:
q = mc∆T
q is the heat energy your trying to find out
m is the mass of water (150g)
c is the specific heat capacity of water (4.18)
∆T is the temperature change (96.3-38.8)
so just multiply m c and ∆T to find q in joules
Answer:
Explanation:
Hrxn = -245.6-296.8+396+50.0 = -96.4 (kJ/mol)
Since Grxn = Hrxn - T*Srxn, where T = 298.15K, we have:
Srxn = (Hrxn - Grxn)/T = (-96.4+75.2)× 1000÷298.15 = -71.1 (j/K mol)
Since: Srxn = Sf (SO2) + Sf (SOCl2)- Sf (SO3) - Sf (SCl2),
or: -71.1 = 248.1 + Sf (SOCl2) - 256.7-184,
Sf (SOCl2) = 256.7+184-71.1-248.1 = 121.5 (J/mol*k)
In order to find T such that Grxn = Hrxn - T*Srxn >= 0. since Hrxn is negative and Srxn is positive, Grxn will always be less than zero. Therefore there won't be a temperature point at which the reaction is going to be non-spontaenous
