The epicenter is determined to be located on a circle that is centered around Recording station X, with a radius extending 250 km.
Answer: The Answer is A.
Explanation:
The energy of a photon is directly related to its electromagnetic frequency, meaning it is inversely related to the wavelength. A higher frequency results in greater energy for the photon. Conversely, a longer wavelength corresponds to lower energy levels.

The accompanying illustration depicts the structure of dimethyl terephthalate. Explanation: Dimethyl terephthalate, whose chemical formula is C6H4 (COOCH3) 2, is a diester derived from terephthalic acid and methanol. It appears as a white solid. Another method of syntheses involves p-xylene and methanol, characterized by an oxidation process followed by esterification.
Answer:
C a B r 2 ( a q ) + N a 2 S O 4 ( a q ) ⟶ 2 N a B r ( a q ) + C a S O 4 ( s )
Explanation:
A precipitation reaction involves a displacement process where a solid precipitate forms. This precipitate, being solid, is distinct from the other products and can be separated.
C a 2 + ( a q ) + S O 4 2 − ( a q ) ⟶ C a S O 4 ( s )
This equation is incorrect as it results in only C a S O 4.
C a B r 2 ( a q ) + N a 2 S O 4 ( a q ) ⟶ 2 N a B r ( a q ) + C a S O 4 ( s )
This is the proper reaction where C a S O 4 precipitate is produced.
C a 2 + ( a q ) + 2 B r − ( a q ) + 2 N a + ( a q ) + S O 4 2 − ( a q ) ⟶ 2 N a + ( a q ) + 2 B r − ( a q ) + C a S O 4 ( s )
This equation illustrates the ionic details of the precipitation reaction.
