Answer:
The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups.
Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels.

<u>Answer:</u>
Hg gets reduced
(Look at the equation; notice how Hg loses O while Zn gains it)
Answer:
ya thats right
Explanation:
here is one explanation i found on the web:
Answer: The true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".
Explanation:
The electric force is due to the forces acting between the charges. The magnetic force is the force exerted between the magnets or moving charged particles.
The electromagnetic force is created by the magnetic field and the electric field.
The magnetic force is related to the electric force. These forces are different aspects of single electromagnetic force. The moving charge produce the magnetic force. The moving magnet produce the electric forces. The interplay of electric field and the magnetic force is the basis for motor.
Motor converts the electrical energy into mechanical energy. The operation of a motor depends on the relationship between electric and magnetic forces.
Therefore, the true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".

Answer:
Excretion is the process of removing wastes from the body. Organs of the excretory system include the kidneys, large intestine, skin, and lungs.
The excretory system removes metabolic wastes from the body. The major organs of excretion are the kidneys, a pair of bean-shaped organs located below the liver. The kidneys filter blood and regulate water balance in the body
