Sodium bicarbonate is used for cleaning, as a food preservative, and as an antacid.

Sodium bicarbonate is used in baking, medicine, and cleaning.

Teflon is primarily used for non-stick coatings in cookware due to its low friction properties.

The principal quantum number (n) corresponds to the shell number. For the 4th shell, n=4.

The principal quantum number n for the 5d subshell is 5.

The ground state of a hydrogen atom corresponds to n=1.

The principal quantum number (n) indicates the energy level of an electron. For a 3p orbital, n = 3.

The principal quantum number (n) indicates the energy level of an electron. For the 4s orbital, n = 4.

Chlorine has an atomic number of 17, and its outermost electrons are in the n=3 shell.

Potassium has the electronic configuration [Ar] 4s1, so the principal quantum number of the outermost electron is 4.

Chlorine has an atomic number of 17, and its valence electrons are in the n=3 shell.

cot^(-1)(0) = π/2

sec^(-1)(2) = π/3, since sec(π/3) = 2.

The principle behind a lever is mechanical advantage, which allows a smaller force to lift a larger load.

A potentiometer measures voltage by balancing it against a known voltage, allowing for accurate voltage measurements without drawing current from the circuit.

Thermometers work on the principle of expansion of liquid (like mercury) with temperature.

Archimedes' principle states that a body submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced.

Electromagnetic induction is based on the principle that a changing magnetic field can induce an electric field and vice versa.

Nuclear fission is the process where a heavy nucleus splits into two or more lighter nuclei, releasing energy.

Sonar technology is based on the reflection of sound waves to detect objects underwater.

The Doppler effect is the change in frequency (and wavelength) of a wave in relation to an observer moving relative to the wave source.

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Lasers operate on the principle of stimulated emission, where an incoming photon stimulates an excited electron to emit a photon of the same energy, phase, and direction.

A polarimeter measures the angle of rotation of polarized light as it passes through a sample, which can indicate the concentration of optically active substances.

Transformers operate on the principle of electromagnetic induction, where a changing magnetic field induces an electromotive force (EMF) in a coil.

Electric generators operate on the principle of electromagnetic induction, converting mechanical energy into electrical energy.

Electric motors operate on the principle of the Lorentz force, where a current-carrying conductor in a magnetic field experiences a force that causes it to rotate.

3D movie glasses use polarization to filter different images for each eye, creating a three-dimensional effect.

A hydraulic lift works on Pascal's law, which states that pressure applied to a confined fluid is transmitted undiminished in all directions.

Sonar works on the principle of reflection of sound waves to detect objects underwater.
