3) In hardware design, a prototype is a hand-built model that represents a manufactured (easily replicable) product sufficiently for designers to visualize and test the design. The word prototype comes from the Latin words proto, meaning original, and typus, meaning form or model.
In chemistry, a salt is an ionic compound which is made up of two groups of oppositely charged ions. The ion with a positive charge is called a cation, and the one with a negative charge is called an anion.
Introduction and Definitions: A salt is any compound which can be derived from the neutralization of an acid and a base. The word neutralization is used because the acid and base properties of H + and OH-are destroyed or neutralized. In the reaction, H + and OH-combine to form HOH or H 2 O or water molecules. A neutralization is a type of double replacement reaction. A salt is the product of an acid-base reaction and is a much broader term then common table salt as shown in the first reaction. The following are some examples of neutralization reactions to form salts. b.
