4.4: Oxidation-Reduction Reactions - Chemistry LibreTexts

Apr 14, 2021· Fractional oxidation states are allowed because oxidation states are a somewhat arbitrary way of keeping track of electrons. In fact, Fe 3 O 4 can be viewed as having two Fe 3 + ions and one Fe 2 + ion per formula unit, giving a net positive charge of +8 per formula unit. Fe 3 O 4 is a magnetic iron ore commonly called magnetite. In ancient times, magnetite was known as lodestone because it

Pyrotechnic composition - Wikipedia

A pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas/smoke or a coination of these, as a result of non-detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction. Basic types of pyrotechnic compositions are:

Produce a Rich Rust Patina on Iron and Steel, Safely and

why hybrids need a Nickel Metal Hydride (NiMH) battery

Mar 18, 2005· For example, you don’t need all your horsepower to go 65 mph down a flat street that you do need if you want to go 65 mph up a hill. But upon ascent, the motor-generator, powered by the NiMH battery, kicks in and provides the extra horsepower. The 2005 Lexus RX 400h internal coustion engine has a horsepower of 205.

How can I determine the formula of an acid? | Socratic

Oct 09, 2015· First you need to determine if the acid is binary (only H and one other element) or ternary (H and more than one other element). Binary acids will have names which begin with the prefix "hydro". The ending of the name for the acid will come from the second element found in the acid. HCl = hydrochloric HBr = hydrobromic Notice how chlorine changes to chloric and bromine changes to bromic.

Acid Etching : 7 Steps (with Pictures) - Instructables

The basic idea is you want to create a barrier so the acid can''t reach the steel. This will leave a pattern when the etch resist is removed. Where ever you have exposed metal will be darkened and marked by the acid. I''ve experimented with nail polish, sharpie marker, vinyl, stickers, electrical tape and different stenciling materials.

Etching - Wikipedia

Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. In modern manufacturing, other chemicals may be used on other types of material. As a method of printmaking, it is, along with engraving, the most important technique for old master prints, and remains in wide use today.
