Answer: C. Miller and Urey showed that inorganic compounds could combine to form the building blocks of living cells.

Explanation:

The Miller and Urey were the two scientists who created the atmospheric conditions that were expected to be present on primitive earth. They demonstrated that several organic compounds have been formed spontaneously from the inorganic compounds like water, ammonia, methane and others.

The exposure of mixture of inorganic compounds by the lightening lead to the formation of organic molecules like amino acids which are the building blocks of life. This was similar to the penetration of earth atmosphere by UV radiation producing the organic compounds from inorganic molecules.

Why do superheating and supercooling occur?

pantera1 [17]

Supercooling and Superheating. "superheating". Generally speaking, a substance undergoes a "phase change" from liquid state to gaseous state when it is heated to its boiling point.
"Supercooling" is the process of chilling a liquid below its freezing point, without it becoming solid.

Type the half-cell reaction that takes place at the anode for the cobalt-silver voltaic cell. Indicate the physical states of at

VashaNatasha [74]

Answer:

Co(s)→Co3+(aq)+3e−

Explanation:

The half-cell reaction may be defied as the reaction taking place at an individual anode or cathode. The oxidation and reduction reactions occur at the electrodes.

Oxidation reaction occur at anode and reduction reaction at cathode. The half-cell reaction for cobalt silver voltaic cell, the oxidation of cobalt occurs at anode. The cobalt loses its 3 electrons and converted to aqueous state from the solid state.

Thus, the reaction at anode is Co(s)→Co3+(aq)+3e− .
