In the reaction,
Cr3+(aq) + 6H2O -------> [Cr(H2O)6]3+(aq)
Cr3+ IS THE LEWIS ACID H2O is the Lewis base.
A Lewis acid is a compound or chemical that accepts a lone pair of electrons. In the above equation, Cr3+ is accepting the lone pair of electrons.
88 Grams because the principal of conservation of mass states total mass in equals total out so 200 in 122+88=200 out
E. The nuclear fuel in the stars will eventually burn out, making the universe a cold and dark place
Answer:
The second law of thermodynamics.
Explanation:
The global transfer of energy from fuels to electricity is about 35% efficient is most likely a consequence of the second law of thermodynamics. This second law states that as energy is transformed more it is wasted, also that the entropy of a system remains constant or increase, but never decrease over time. That is why is impossible to convert heat energy to mechanical with 100 % efficiency.
Therefore, in the production of electricity, a minor part of chemical energy (from fuels) will be transformed into energy and the rest will be lost to the environment, mostly as heat, to satisfy the second law of thermodynamics.
