An acid can not survive in a basic medium.
CH3-COOH + NaOH -------> CH3-COONa + H2O

Polymers are broken down into monomers through a process called?
Condensation. The opposite is known as dehydration synthesis.
What hydrogen ion is released by a carboxylic acid?
A carboxylic acid has the form:R-COOH or R-C(=O)OHWhere R is a hydrocarbon chain.A diagram from Wikipedia:The Hydrogen attached to the OH the one released by the acid.In reality, both bonds to the oxygen probably have some aspect of being 1 1/2 bonds rather than true double bonds (resonance), although, apparently in the acid form they are of different lengths. However, the bond lengths equalize when in the conjugate base form.
Why is butter becoming rancid a chemical change?
This is a purely chemical reaction. The reason why is simply because bacteria in the butter is turning the lactose and sugars found in butter into lactic acid.
How a strong acid and a weak acid behave differently when each is dissolved in water?
The strong acid could cause an exothermic reaction (produce a lot of heat) Weak acid do the same, but do not produce such a strong exothermic reaction. Acid in Water might be a thrill Water in Acid could be rather unpleasant. Regards.
Why do most materials produce oxides rather than nitrides?
Oxygen is much more reactive than nitrogen, somewhat more common than nitrogen, and tends to form much more stable compounds than nitrogen.
What was carboxylic acid used for?
Rather than there being a substance called carboxylic acid, scientists call the-COOH group that occours frequently in many different compounds the carboxylic acid functional group.
How are carboxylia acids produced?
Generally 3 types or reactions are used to produce carboxylic acids:(1) Hydrolysis (i.e. reacting with water) of carboxylic acid derivatives such as esters, amides, anhydrides, acid halides, or nitriles.(2) Oxidation of primary alcohols & aldehydes(3) Grignard reactionThese are found in any organic chemistry book. The explanations are rather lengthy to include here plus I'm not sure of your general knowledge of organic chemistry so you can understand it. But hopefully that helps. Post another question if you want more specific information.
Why acylation occur at phenol rather than carboxylic acid in salicylic acid?
This is actually quite simple: the pKa of the carboxylic acid group is only about 3, but the pKa of the phenolic group is 13.4.

What characteristics of a molecule make it an amino acid?
Being both an amine and an acid, of course.Generally the term is used mainly for a specific type of amino acids... alpha-amino carboxylic acids. However, taurine is also called an amino acid, despite the fact that it's a sulfonic acid rather than a carboxylic acid.(alpha-amino means the amine group is attached to the first carbon after the carboxylic acid carbon itself. In taurine, the amine group is attached to the second carbon after the sulfonic acid group.)
Which object in space produces rather than reflects light?
All stars produce light rather than reflecting light.
What are two everyday neutralisation reactions?
A) Washing up - When using anionic surfactants and soaps, these neutralise the fatty acids in the oil and produce esters (Known as esterification) B) Washing powder - The principle is the same as A), but the alkali is not soap, but rather NaOH produced by the temporary hydrolysis of Na2CO3: Na2CO3 + H2O <--> NaOH + H2CO3 Because NaOH is a stronger base than H2CO3 is acidic, the solution is overall alkali.
Why does the US import clothing rather than produce it?
The US imports, exports, and produces clothes.
What is the difference between amino acids and peptides?
amino acids contain an amine and a carboxylic acid
An organism that uses rather than produces is what?
An organism that uses rather than produces is called a comsumer

Can some autotrophs obtain their energy from chemicals rather than sunlight to produce carbohydrates?
Yes, hydrogen sulfide
