Answer:

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.

Option C is correct.

What happens when a chemical change occurs
Alona [7]
Chemical change happens when a substance combines with another substance to form a new substance. It produces chemical reactions and generally is not reversible except by further chemical reactions. Heat is sometimes produced in some reactions. When chemical reactions occur, the atoms are rearranged and an energy change happens along with it as new products are generations. At a molecular level, chemical changes involves the making or breaking of bonds between atoms. Some examples of chemical change are iron rusting (iron oxide forms) and bread rising (yeast converts carbohydrates into carbon dioxide gas).

According to the Octet Rule, an element is most stable with ______________ valence electrons
Len [333]
Eight because an octet has 8 electrons and when it’s full it’s stable. If it’s not full, it’s constantly sharing or borrowing electrons.

For the following reaction, identify the element that was oxidized, the element that was reduced, and the reducing agent. Give a
Volgvan

<span>For this reaction, oxidation number of Carbon in CO would be +2 while oxidation number of carbon in CO2 would be +4 and so this means that carbon has oxidized. Oxidation number of nitrogen in NO is +2. While oxidation number of nitrogen in N2 is 0 so this means that nitrogen had reduced. The reducing agent is the one which provides electrons by oxidizing itself so in this case; CO is the reducing agent while the C in CO oxidized to produce electrons. </span><span>I am hoping that this answer has satisfied your query about and it will be able to help you, and if you’d like, feel free to ask another question.</span>

What is 0.00034 in exponential form
Verizon [17]

Answer:

3.4  ×  10 ^− 4

Explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
