Answer:- 10 L of ethane.
Solution:- The given balanced equation is:
![2C_2H_6(g)+7O_2(g)\rightarrow 4CO_2(g)+6H_2O(g)](https://tex.z-dn.net/?f=2C_2H_6%28g%29%2B7O_2%28g%29%5Crightarrow%204CO_2%28g%29%2B6H_2O%28g%29)
From this equation, ethane and oxygen react in 2:7 mol ratio, the ratio of volumes would also be same if they are at same temperature and pressure.
Since 14 L of each gas are taken, the oxygen will be the limiting reactant and ethane will be the excess reactant. Let's calculate the volume of ethane used:
![14LO_2(\frac{2LC_2H_6}{7LO_2})](https://tex.z-dn.net/?f=14LO_2%28%5Cfrac%7B2LC_2H_6%7D%7B7LO_2%7D%29)
= ![4LC_2H_6](https://tex.z-dn.net/?f=4LC_2H_6)
From above calculations, 4 L of ethane are used. So, excess volume of ethane left after the completion of reaction = 14 L - 4 L = 10 L
Hence, 10 L of ethane will be remaining.
Answer
During the process of polymerization,
<h2><em>
monomers</em></h2>
combine by sharing electrons. This process forms a

Answer:
C. Among the metals
Explanation:
The best place to look for this element that has this property is among the metals.
The ability of a metal to be malleable and possibly drawn to a sheet is a manifestation of their metallic bonding. Metallic bonds are very predominant among metals and their alloys.
This bond type determines the bulk of the physical properties of metals.
One of such is their ability to drawn into thin sheet, it is called malleability.
