Sort of. First off rubbing alcohol doesn't have to be all alcohol, it can be some water in it too, and water can promote rust. Next thing rubbing alcohol can remove a possibly protective layer of grease, which can make metal rust faster.

How does vinegar affect steel?
In the case of Low Carbon Steel, the acetic acid in the vinegar could react and create Iron Acetate. If the Steel is completely submerged and not exposed to air, a dark orange material can form on the bottom of the container that is insoluble in water. In the case of Stainless Steel, vinegar is often used to clean cookware.
What is the full form of SFRC?
steel fiber reinforced concrete
When will liquid alcohol change to vapor?
Any form of liquid alcohol will change to vapor when its temperature reaches the boiling point (different for each type of alcohol).Alcohol (ethyl alcohol) is a volatile liquid and changes in to vapours at every temperature although its boiling point is 78.5 Celsius.
What substance would be expect if a test tube containing yeast glucose and water after 24 hours?
You just might get some CO2. (That's a gas.) The yeast cells will ferment the glucose in to ethyl alcohol and Carbon dioxide. The CO2 being in the gaseous form will diffuse in the atmosphere and in the test tube, ethyl alcohol in diluted form with water will be found.
Why absence of air conditions are used in fermentation?
In alcoholic fermentation, oxygen will react with the alcohol to form acetic acid.
Does rubbing alcohol contain particles of matter?
All solids, liquids, and gasses are considered matter. Rubbing alcohol is usually in a form of matter known as isopropyl alcohol.
What does isopropyl alcohol burn down to?
Isopropyl is C3H7OH. Burning (adding O2) produces only CO2 and H2O (in the form of steam). The balanced chemical formula is: 6 C3H7OH + 25 O2 --> 18 CO2 + 22 H2O
How do you remove oxide layer from steel after vacuum heat treatment?
It is important to heat treat in vacuum as otherwise lots of oxides form; after heat treat in vacuum oxides are removed, if part small enough, by use of an abrasive grit pad, such as Scothbrite A, and cleaned with acetone followed by isopropyl alcohol. If not protected, however, oxides will continue to form in air
Why does a thin layer of water repel a drop of rubbing alcohol?
A thin layer of water might repel a drop of alcohol, however rubbing alcohol is miscible in water in larger quantities. Isopropyl alcohol, of the form C3H7OH, is what we know as rubbing alcohol. The repulsion could be because of the propyl group, however the hydroxyl group should form intermolecular hydrogen bonds with water.
Will charcoal dissolve in water?
charcoal is made from wood. It's a smoked and dehydrated form of black solid and will not dissolve in water.
What chemicals are in rubbing alcohol?
Usually water and Isopropyl Alcohol and sometimes some aromatic fragrances. Isopropyl alcohol is made up of carbon, hydrogen, and oxygen (C3H7OH), which makes it an organic compound. Isopropyl alcohol comes from wood grain. Rubbing alcohol is typically 70% isopropanol and 30% water. Isopropanol is propane (C3H8) with one of the middle hydrogens knocked off and replaced with a hydroxyl (OH). The formula for isopropanol is C3H8O, or writing the formula to show how the atoms are connected, it would be (CH3)2CH-OH Should be nothing more than isopropyl alcohol and perhaps some water. Some preparations also add some food coloring (green, usually), so it doesn't look like water.
What form does alcohol come in?
Characteristics of an alcohol molecule: -A straight chain of carbon and hydrogen -an OH group attached to the carbon-hydrogen skeleton -no other functional groups attached Ex: methanol CH2OH (wood alcohol) ethanol C2H5OH (grain alcohol) isopropyl alcohol C3H7OH (rubbing alcohol) There are various other forms these are the most familiar to most people.
What would I use a stainless steel cap screw for?
steel cap screws are used where there is danger of rust because steel cap screw are resistant to corrosion because they form a tough oxide layer when exposed to oxygen. the strength of stainless steel is very good
What is alcoholic acidity?
Alcohols can easily oxidise to form carboxylic acids when exposed to the air (this is why the dregs of a bottle can be sour). Alcohol acidity is a way of measuring how much of the alcohol content has been converted this way.
What is rubbing alcohol made out of?
Active Ingredients Ethyl Alcohol by Volume 70% Ingredients Denatonium Benzoate , Methyl Isobutyl Ketone , Water The ingredients will be listed on the bottle. There are two standard kinds of rubbing alcohol: (1) one made with isopropryl alcohol, which has a certain toxicity but is more pleasant or neutral smelling; and (2) one made with ethyl alcohol with an added denaturing agent to make it inedible. The ethyl alcohol (ethanol) variety has a bitter or sour or unpleasant smell, and is therefore much less popular than the isopropryl alcohol variety. This is why even though the pharmaceutical definition for "rubbing alcohol" is denatured ethyl alcohol, isopropryl alcohol is far more available commercially and is also labeled as "rubbing" alcohol. The uses of both varieties are the same, although isopropryl alcohol, because of its inherant toxicity, carries warnings about overuse and safe handling. According to Wikipedia.org1: Common, over the counter "Rubbing Alcohol" in pads or in fluid form is generally 60-70% solution of isopropanol in water. Although Isopropanol is sometimes sold as "Isopropyl Rubbing Alcohol, 70%" and "Isopropyl Rubbing Alcohol, 99%" (harder to find but generally more useful for experimenters & cleaning uses), there is no isopropyl alcohol in the United States Pharmacopeia formula for Rubbing alcohol, U.S.P.. It is used as a disinfectant, and is a common solvent.
Is exposed an adjective?
It can be (an exposed negative, exposed secrets). The word exposed is a form of the verb to expose (to reveal).
How is steel coated with black oxide like on gun barrels to protect them from rust?
It is a form of controlled rust. In hot bluing, the steel parts are placed in a hot chemical bath that changes the outer layer of steel to black iron oxide. This helps protect the steel beneath it from further rusting. In rust bluing, the steel is exposed to moist air, and allowed to rust under controlled conditions.
