These cells are found in applications for the military, for example in Mark 37 torpedoes and on Alfa-class submarines. in the 1960s General Motors developed an electric car called Electrovair, which was powered by a zinc-silver battery produced by Eagle-Picher. [5] However, the battery was expensive and lasted only a hundred charge-discharge ...
The zinc–air cell is a primary cell (non-rechargeable); recycling is required to reclaim the zinc; much more energy is required to reclaim the zinc than is usable in a vehicle. An advantage of utilizing zinc–air batteries for vehicle propulsion is the mineral's relative abundance when compared to lithium.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

A cheat sheet that is used contrary to the rules of an exam may need to be small enough to conceal in the palm of the hand Cheat sheet in front of a juice box. A cheat sheet (also cheatsheet) or crib sheet is a concise set of notes used for quick reference.
Fuel cells are different from batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy comes from chemicals already present in the battery. [citation needed] Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied.
The flow of cytoplasmic components plays an important role in many cellular functions which are dependent on the permeability of the cytoplasm. [8] An example of such function is cell signalling , a process which is dependent on the manner in which signaling molecules are allowed to diffuse across the cell. [ 9 ]
In electrochemistry, cell notation or cell representation is a shorthand method of expressing a reaction in an electrochemical cell.. In cell notation, the two half-cells are described by writing the formula of each individual chemical species involved in the redox reaction across the cell, with all other common ions and inert substances being ignored.
