- Boron
- Silicon
- Germanium
- Arsenic
- Antimony
- Tellurium, and possibly
- Bismuth

are found near the center of the P-block or main block of the periodic table.
Explanation:
The answer is; 2.
To balance a chemical equation, the moles on one side of the equation has to be the same as that on the other side. This ensures that the law of conservation is observed because matter or energy can't be created or destroyed but can only be transformed from one form to another.
In this equation, putting 2 in front of NaCl ensures that there are 2 moles of Na and CL just as there are 2 moles of Na and CL in the reactants side.
Answer:
Simple harmonic motion is the movement of a body or an object to and from an equilibrium position. In a simple harmonic motion, the maximum displacement (also called the amplitude) on one side of the equilibrium position is equal to the maximum displacement.
The force acting on an object must satisfy Hooke's law for the object to undergo simple harmonic motion. The law states that the force must be directed always towards the equilibrium position and also directly proportional to the distance from this position.
Answer: Technician A
Explanation: The major cause of solenoid clicking in cars is a dead or low battery. That should be the first point of check when a car clicks or starts to develop a hard start suddenly. The battery which plays an integral role in the ignition process of vehicles can sometimes run low and maybe unable to create enough charge to power the engine.
In the case of a solenoid clicking the battery should be carefully checked either to be recharged or changed if faulty.
