It could tell you how much mass contains inside
Answer:
Explanation:
14:
a) Shared pairs = 6
per shared pair between each C-H bond.
and two shared pair between C=C thus total shared pairs are 6
a) Lone pairs = 0
b) Single bonds = 4
Double bonds = 1
Triple bonds = 0
c) Formula = C₂H₄
Name = Ethene
d) Lewis structure = given structure is also Lewis structure.
13:

Name = Dinitrogen
d) Lewis structure = given structure is also Lewis structure.
Answer: A) 0.20 L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of stock 
solution = 10.0 M
= volume of stock solution = ?
= molarity of dilute solution = 0.50 M
= volume of dilute solution = 4.0 L
Therefore, the volume of 10.0 M solution needed to prepare 4.0 L of 0.50 M is 0.20 L
If you are trying to observe a cell wall, you should look at a plant cell. There are only two different types of cells, which are plant and animal cells. The plant cell is the only one which contains a cell wall. Animal cells actually only have a <em>cell membrane. </em>
