Three carbon atoms are linked by single covalent bonds such that they form the shape of a v. all of the unshared electrons form covalent bonds with hydrogen. how many hydrogen atoms does this molecule contain?
a) 2
b) 6
c) 8
d) 4
e) 10

C) 8

Explanation:

Total number of carbon atoms = 3

Number of single bonds = 3

So, each carbon is bonded to the next carbon with the single bond, Number of unshared electrons left with the terminate carbons are 3 and with the intermediate carbon is 2.

Thus, the two terminate carbon have 3 hydrogen each and the intermediate will have 2.

Total - 8

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the answer is na (sodium)
