What is the difference between white and red rusts?

"rusts" are actually metallic oxides. Ferrous oxide is reddish brown. Zinc oxide is white. Aluminum oxide is whitish gray.

C- longer wavelength.  Red is the long (low fequency) end of the spectrum, and violet is at the short end (high frequency).

The more surface area is open to the air, or oxygen, the faster it rusts.  That's why a sheet, which is pretty much totally exposed, will rust fast, but not thick parts like the engine, etc.  Rust, after all, is the product of Iron mixing with Oxygen.  Also, steel is a mixture, more specifically a metal alloy, of iron with carbon.  Alloys with higher carbon content than this are known as cast iron.  Therefore, cast iron rusts slower than sheet metal also because it contains a lot of carbon, rather than being all iron.  I don't know what is better for the garden, but "cast iron" is actually steel, with high amounts of carbon in it.

vinegar is a solution of acetic acid (9% in water). Acetic acid (CH3COOH) is a weak acid that disolve rust (FeOOH according ones or Fe3O4 according another ones)\n\nSo, a soluble salt is obtained: (CH3COO)3Fe

Chromium is added to the steel. This actually provides a hard oxidation layer. So basically, there is already a layer of oxide (kinda like rust), but it doesn't flake off like the redish type rust you might see on your car. This layer actually protects the rest of the material, by keeping other impurities from reacting with the interior (or exterior).

Fusiform Rust Fungus  is caused by pathogenic fungus Cronartium quericum f. sp. fusiforme.Another is canker. The first visible sign of fusiform infection is a small, elongated swelling on one side of or completely encircling a stem or branch. These swellings grow throughout the season but produce orange spores only in early spring. Some cankers will not produce spores for three or four years and may appear dead, but they will begin producing spores again the next year. A portion of the old canker occasionally will die. This causes a flat or depressed canker, which sometimes gives off large amounts of resin.Some people believe that fusiform may spread through the system of the tree, causing the formation of new cankers. This is not true. Each canker is the result of a separate infection and damages only that part of the tree. Branch cankers, however, often grow down into the trunk and develop into a damaging stem canker.

Almost all of them actually. The rusting of iron forms a red colour,  the burning of a match forms a black color and so forth. Think of any chemical reaction and it will most likely include a colour change.

Why not? Iron and oxgen form a number of compounds of both determinate and indeterminate composition. Someone want to give me the exact formula for rust?

Josh has the right idea, but there's one big flaw. It's not rust. Rust is hydrated iron (III) oxide (Fe2O3). The iron in oxygen-carring hemoglobin is at a +2 state, not a +3 state. The red is not caused by rust in the bloodstream.\n\nIf the iron in hemoglobin is oxidized to a +3 state, it turns the molecule into hemiglobin or methemoglobin, not hemoglobin. Neither of those two molecules with Fe+3 states can bind with oxygen.\n\nBasically, blood is red because of the oxygenated hemoglobin. Oxygenated hemoglobin is bright red, while blood without oxygen is a darker red. It's a myth that veins carry blue blood--it's an optical effect by the skin that makes it appear blue. If you get a blood test done, they'll pull out blood from a vein which is dark red, not blue.\n\nHope this helped.

Other than the colour, the red is used for First-Class & Test Matches, the white with coloured clothing for 1-Dayers.\n\nEffectively, the white is usually a little harder and the seam is more pronounced. That means that it tends to swing,seam & often bounce a bit more earlier on. It is why some bowlers, Brett Lee & Alan Donald for example, have preferred to use a slightlier older ball in 1-Day Cricket.\n\nOften with the white ball, it will lose its colour towards the end of an innings, which is why it is often changed around the 45 over mark. This is a major reason why it hasn't been experimented with in the longer form of the game.\n\nhope this helps.

it is a reddish color.  This is from the iron deposits on the surface that have oxidized(rusted).  Its like a rusty planet.

White Gold\nWhite gold is an alloy of gold and some white metals such as silver and palladium. White gold can be 18ct, 14ct, 9ct or any karat. For example, 18ct yellow gold is made by mixing 75% gold (750 parts per thousand) with 25% (250 parts per thousand) other metals such as copper and zinc. 18ct white gold is made by mixing 75%Traditionally nickel was used in white gold, however, nickel is no longer used in most white gold made today as nickel can cause reactions with some people. We do not use nickel in our white gold gold with 25% other metals such as silver and palladium. So the amount of gold is the same but the alloy is different.\nWhen white gold rings are new they are coated with another white metal called Rhodium. Rhodium is a metal very similar to platinum and Rhodium shares many of the properties of platinum including its white color.\n\nPlatinum\nPlatinum is a white metal, but unlike gold it is used in jewellery in almost its pure form (approximately 95% pure). Platinum is extremely long wearing and is very white, so it does not need to be Rhodium plated like white gold. \nPlatinum is very dense (heavy), so a platinum ring will feel heavier than an 18ct gold ring. \nPlatinum is, however, very expensive. A platinum ring will be approximately twice the price of an 18ct white gold ring (excluding gemstone costs).

White is 7 deg. f. cooler than black. White paint can be loaded with titanium oxide which has better heat transfer properties.

Blood does not contain enough iron to rust (rust is FeO2).  Rust is caused by the synthesis reaction:\n\n             Fe  +  O2 -------> FeO2\n\nWithout the right circumstances this will not happen, the right circumstances being that there be enough iron there for the reaction to occur.

I am not sure about rust, but I know that each 12 ounce can of Coke contains 10 teaspoons of sugar.  (That is what my chemistry college professor told me).
