Which phrase describes a polymer? A. a branching structure containing 10 carbon atoms and 22 hydrogen atoms B. a crystal contain
ing many sodium ions and many fluoride ions C. a long chain of carbon atoms with hydrogen atoms attached to them D. a molecule containing six carbon atoms arranged in a ring structure E. a single atom of calcium bonded to two atoms of chlorine
C. A long chain of carbon atoms with hydrogen atoms attached to them
Explanation:
For example, the main component of flour is starch and starch is a polymer.
Now, Starch is a polymeric carbohydrate that consists of a large number of glucose units which are bonded by chemical bonds known as glycosidic bond. It's also known that Starch is a white, tasteless and odorless powder that is not soluble in alcohol or even cold water.
Thus, we can say that polymer is a long chain of carbon atoms with hydrogen atoms attached to them.

Explanation: In an endothermic reaction, it takes more energy to break the bonds of the reactants than is released when the bonds in the products are formed. In an endothermic reaction, the temperature goes down.
