Explanation

 XeF2 has two fluorine atoms bonded to a central xenon atom, with the lone pairs on the xenon arranged in an equatorial plane.

This results in a linear structure where the fluorine atoms are directly opposite each other along a straight line. 

Explanation

Acetic acid (CH3COOH) has the highest boiling point among the given options due to its strong capacity for hydrogen bonding.

Explanation

The diameter of an atom is in the order of 0.2 nanometers (nm), or 200 picometers (pm), which is equivalent to 2 x 10^-10 meters.

Explanation

A light year is the distance light travels in one year.  

   - Since it's a measure of length, its dimension is [L].  

Explanation

A pendulum's swing speed is inversely proportional to the strength of gravity.

Since Earth's gravity is weakest at the equator due to its centrifugal force caused by rotation, the pendulum will swing most slowly there. 

Explanation

The angular momentum of the body remains constant in a uniform circular motion.

Angular momentum is defined as:

The property of any rotating object given by moment of inertia times angular velocity.

Explanation

Cubic meter (Cubic meter is a unit of volume, not distance.)

Explanation

Hemoglobin is the respiratory protein of many arthropods

Explanation

The relative atomic mass of a neutron is approximately 1.0087 amu (atomic mass units), slightly more than that of a proton (about 1.0073 amu)
