The chemical composition of para-aramid is poly para-phenyleneterephthalamide (PPTA). This polymer is composed of alternating benzene ring and amide groups, leading to a rigid, rod-like structure. Characteristics of aramid fibers Aramids fibers show resistance to many solvents and salt, but ...

for example, sodium chloride and add it slowly to a fixed quantity of water. The salt, which represents a low molecular weight compound, dissolves in water up to point ( called saturation point ) but, thereafter,
What is the chemical compound of hypobromite and how to produce it? Which of the following compounds is a salt? Explain your answer: a. C_6H_6 b. NH_4NO_3 c. CH_3CO_2H d. NH_3 Al(OH)_3 Write the formula for the phosphate compound formed with the ammonium ion. Write ...
Which chemical elements tend to make minerals dark? What is an example of a sulfate mineral? What makes a mineral a mineral? What is the charge on the polyatomic ion hydrogen carbonate? What type of compounds always contain carbon and hydrogen?
The elements hydrogen and oxygen combine to form a compound whose composition is expressed by the formula H2O. The molecule of water has the structure shown here. Chemical substances that cannot be broken down into simpler ones are known as elements. The actual physical particles of which elemen...
Similarly, hydrogen and oxygen, which are both gaseous elements can combine to form water, which is a liquid compound, not a gas, at room temperature. The process by which such combinations and transformations of elements into compounds take place is called achemical reaction. ...
Sodium chloride, also known as table salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. It is commonly used as a condiment and food preservative. Salt can be created by adding two very reactive elements together: sodium (Na(s)...
Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater. Sand Small loose grains of worn or...
