Actually, a roux is not a sauce, but is the base for several different sauces and is used as a thickener in many dishes. A roux is made by combining equal parts of fat and starch (usually butter or lard and flour) and cooking it in a pan until the flour taste has been cooked out. The color of a roux depends upon the amount of time you cook it - and the darker the roux, the more flavor it imparts to the dish you are using it in. By adding milk to a roux you are making a bechamel sauce which is used in many lasagna recipes and other dishes. Bechamel sauce is also the base sauce for several other culinary sauces: Mornay sauce (cheese sauce), Mustard sauce, and Sauce Soubise (contains finely chopped onions that are sweated in butter before adding to the sauce) are a few of these.
Yes. Roux is used as a thickener for gravy, soups, stews and other sauces.

Roux is basically an emulsive agent -- butter adds the fat.
roux is a cooked mixture of flour and butter. the darker you cook it the more flavor it gives the final gravy. but be careful not to burn it!corn starch is an uncooked thickening agent that does not alter the flavor of the final gravy or sauce. It is important with corn starch that before adding it to a hot gravy or sauce that you first dissolve it completely in a small amount of cold water, or you will get lumpy gravy or sauce as small "micro dumplings" of cornstarch form.
no
Roux sauce helps thicken anything that it is added to. Watery mushroom soup isn't as appealing as it would be a thick, hearty soup.
Arrowroot or tarter sauce. Both are thickening agents.
there is no substitution. If you are using it fir its thickening properties, try a roux, cornstarch or arrowroot
Mornay sauce starts out as a bechamel sauce (a basic roux of flour, milk & butter). Then it is added with a cheese, such as gruyere.
Bechamel sauce is a variety of white sauce made from a roux of butter and flour, to which hot milk is added.
I believe you're referring to a roux.
Roux is usually used to make a sauce of some kind. Using brown stock with it will most likely give you a delicious brown gravy, as long as you don't mess it up in the process.
