How does geothermal energy differ from solar energy?

Chemistry

Answer:

Whereas solar energy makes use of the sun to generate energy, geothermal energy makes use of the heat that is trapped deep in the center of the earth. The magma buried deep down of our soil is as hot as the sun’s surface, and some of that heat manages to escape outward. When that happens, we can harness that said heat for energy.

Solar panels capture the sun's rays and convert it into heat and electricity, which is used to heat and cool your home, while geothermal solutions use the constant core temperature of the Earth to warm and cool a property.

Use standard reduction potentials to calculate the equilibrium constant for the reaction: 2Cr3+(aq) + Pb(s)2Cr2+(aq) + Pb2+(aq)
inn [45]

Answer:

3.47 ×10^-10

Explanation:

The equation of the reaction is 2Cr3+(aq) + Pb(s)------->2Cr2+(aq) + Pb2+(aq)

A total of two moles of electrons were transferred in the process. The chromium was reduced while the lead was oxidized. Hence the lead species will constitute the oxidation half equation and the chromium will constitute the reduction half equation.

E°cell = E°cathode - E°anode

E°cathode = -0.41 V

E°anode = -0.13 V

E°cell = -0.41 -(-0.13) = -0.28 V

From

E°cell = 0.0592/n log K

n= 2, K= the unknown

-0.28 = 0.0592/2 log K

log K = -0.28/0.0296

log K = -9.4595

K = Antilog ( -9.4595)

K= 3.47 ×10^-10

What is the [H+] of a solution with a pH of 3? Use a scientific calculator.
Mariulka [41]

Answer:

1 x 10⁻³.

Explanation:

∵ pH = - log[H⁺]

3 = - log[H⁺].

log[H⁺] = -3.

∴ [H⁺] = 1 x 10⁻³.
