Vinegar

it makes the bone rubbery and can make it bendy

Drinking vineger and using Frankicense at the same time cause dizzyness and rapid eye movement?

Yes. They eat dead Vinegar bacteria in unpasterized vinegar.

to what three classes in diagram does vinegar belong

Vinegar is the common name for acetic acid, an organic acid often used in red meat production. At concentrations of 5% and less, acetic acid is considered Generally Recognized as Safe (GRAS) by FDA and FSIS and is classified as a processing aid. At concentrations above 5%, acetic acid could be a chemical hazard.

add vinegar to baking soda and collect the carbon dioxide gas produced in a balloon. this is possible in theory, however to inflate a balloon with a gas coming out of a reaction is really more complicated than that.

Carbon, hydrogen and oxygen - so 3.

lactic acid -curd

acetic acid -vinegar

it dries quickly without streaking. . .

another tip. . .use old newspaper (not shiny pages) instead of paper towels to dry the windows. this gets double use out of the newspaper and it works as well as paper towels do

Yes. In fact, rubbing alcohol is already mixed half-and-half with water.

The addition of vinegar (and mild acid) to baking soda (a base or alkali) causes a somewhat violent chemical reaction producing carbon dioxide suddenly.

egg has more water molecules than vinegar so when egg is placed in vinegar water molecules move from the egg to the vinegar due to osmosis,which is defined as "the movement of water molecules from higher concentration to lower concentration thru a partially permeable membrane"

there fore the water molecules move inward. The proof is that the egg got larger and this was because water moved into the egg after the shell disintegrated from the 5% of acid in the vinegar. (the other 95% is water)

Vinegar is a homogeneous mixture.

In most cases both the limestone AND the fossil will be dissolved by the vinegar (eg a crinoid in Carboniferous limestone), so no. However, some fossils (eg echinoderms in the Chalk) are silicified and in these cases dissolving the limestone in vinegar will expose the fossil in spectacular detail and in other cases the fossil will dissolve more slowly than the matrix, so yes. .

In other words there is NO true or false answer, fossil preparation and conservation is a discipline in itself.

Vinegar is a polar solvent and salt is a polar solute. Therefore vinegar dissolves salt. Plus, salt's are very soluable and will almost always completely disassociate when added to water(you vinegar isn't 100% vinegar, there's also lots of plain water than salt can dissolve in.)

A solution of vinegar is obtained with a layer of oil on the top.

No, Talc (Mg3Si4O10(OH)2) does not dissolve in vinegar.

No, In the United States, in order for a vanilla extract to be called pure, the U.S. Food and Drug Administration requires that the solution contain a minimum of 35% alcohol and 13.35 ounces of vanilla bean per gallon.

I think that oil and water are equally dense because when they are put together they blend. If vinegar was denser than water it would sink to the bottom of the water ,but it doesn't just like water doesn't sink to the bottom of vinegar when poured in a same container without mixing.

it is a physical change because no reaction occurs and there is no new substance. :)

yes it does

Why would we be that sad to find that out?!

no

magnesium will react with vinegar ... It will bubble owly and will begin to warm

The only way to know is to weigh it. The mass of two apparently identical flasks is quite variable.
