Is it possible for a city to be located at 120 degrees south and 30 degrees west? explain

Not possible

Explanation:

It is not possible for a city to be located at 120° S and 30° W. It is because the earth is equally divided into into two hemispheres, where the latitudes starts from 0° at equator to 90° at poles, and the longitudes starts from 0° to 180° measuring from east to west direction or west to east direction.

Thus, no place can exist beyond 90° in both the hemisphere.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
