Polyethylene is made from the polymerization of ethylene monomers.

The monomer of polystyrene is styrene, which polymerizes to form polystyrene.

The Paris Agreement was adopted in 2015 to address climate change and its impacts.

The conversion of benzene to phenol is known as hydroxylation, typically involving the addition of a hydroxyl group (-OH) to the aromatic ring.

A concave lens always produces a virtual and upright image regardless of the object's position.

A concave lens always forms a virtual and upright image.

When the object is placed between the focal point and the mirror, the image formed is virtual and erect.

When the object is beyond the center of curvature, the image formed is real and inverted.

When the object is at 2f, the image is formed at 2f on the opposite side, making it real and inverted.

When the object is placed beyond 2f, the image formed by a convex lens is real and inverted.

When the object is beyond the focal point, the image formed by a convex lens is real and inverted.

When the object is at infinity, the rays converge at the focal point, forming a real and inverted image.

When an object is placed beyond the focal length of a convex lens, the image formed is real and inverted.

A convex mirror always forms a virtual image that is upright and smaller than the object.

A plane mirror always forms a virtual and erect image, as the image appears behind the mirror at the same distance as the object.

Using the Nernst equation: E = E° - (0.0591/n) log([Zn²⁺]), where n=2.

The Nernst equation is E = E° - (RT/nF)lnQ, where E is the cell potential, E° is the standard potential, R is the gas constant, T is the temperature, n is the number of moles of electrons, and F is Faraday's constant.

The Nernst equation is used to determine the cell potential under non-standard conditions.

The Nernst equation is used to determine the cell potential under non-standard conditions.

According to Newton's first law, if the object is moving with constant velocity, the net force is 0 N.

An object at rest has no net force acting on it, according to Newton's first law.

The net gain of ATP molecules from one molecule of glucose during aerobic respiration is approximately 30-32 ATP.

The series follows an alphabetical order, so the next figure is D.

The pattern is that each letter is two places ahead in the alphabet. G + 2 = I.

The series consists of every second letter in the alphabet: D, F, H, J, L.

The series is the Fibonacci sequence where each number is the sum of the two preceding ones. The next number is 3 + 5 = 8.

The differences are 1, 2, 3, 4, which increase by 1 each time. 11 + 3 = 14.

The series consists of perfect squares: 1^2, 2^2, 3^2, 4^2. The next number is 5^2 = 25.

The series increases by 10 each time: 10, 20, 30, 40, next is 50.

The series adds 10, 10, and then 20. The next addition is 30, so 50 + 30 = 80.
