Bao + .....Co2... --> BaCO3 + ......
Answer:
magnesium
Explanation:
magnesium has fewer valence shells meaning that the protons have a stronger hold on the electrons and it would take more energy to remove an electron to create an ion.
We have to answer based on basic concept on electron.
The correct answer is: Since electrons repel each other, electrons pairs will be as far apart as possible.
We know, electrons are negatively charged particles and negatively charged particles repel to each other.
When electrons which are of similar charge repel each other, they go far apart from each other..

Answer:- 10 L of ethane.
Solution:- The given balanced equation is:

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:

= 
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.
