Answer:
Polymers are used in everything from nylon stockings to commercial aircraft to artificial heart valves, and they have a key role in addressing international competitiveness and other national issues.
Polymer Science and Engineering explores the universe of polymers, describing their properties and wide-ranging potential, and presents the state of the science, with a hard look at downward trends in research support. Leading experts offer findings, recommendations, and research directions. Lively vignettes provide snapshots of polymers in everyday applications.
The volume includes an overview of the use of polymers in such fields as medicine and biotechnology, information and communication, housing and construction, energy and transportation, national defense, and environmental protection. The committee looks at the various classes of polymers—plastics, fibers, composites, and other materials, as well as polymers used as membranes and coatings—and how their composition and specific methods of processing result in unparalleled usefulness.
Answer: 4.52x10²⁴ atoms Li
Explanation: For 1 mole of Li it is equal to the Avogadro's Number.
Solution:
7.5 moles Li x 6.022x10²³ atoms Li/ 1 mole Li
= 4.52x10²⁴ atoms Li
Answer and Explanation:
The substance that does the dissolving (or dissolves in the solution) is the <u>solute</u>.
- The solute is the substance that is being dissolved
The substance that makes the solute dissolve is called the <u>solvent.</u>

Answer:
C rusting iron
Explanation:
water evaporating and melting is an example of physical change it doesn't change the H2O composition of the atoms, rubbing water on paper doesn't change any atoms or molecules. so the only answer that leaves is rusting iron because when an iron nail comes into contact with water and is then exposed to the air, it rusts, forming a brown-red substance. This process changes the chemical composition of the original substance.
