.
Volume of
, 
To Find :
Volume needed(
).
Solution :
We know,

Hence, this is the required solution.
Answer:
1 and 2
Explanation:
When Concentrated H2SO4 reacted with the alcohols, they produce cycloalkenes. This is a mechanism known as dehydration of alcohols with an acid catalyst. This is because concentrated H2SO4 acts as a great oxidizing agent. In the process, the alcohols are heated to a high temperature with an excess of pure sulfuric acid. By passing the gases through a sodium hydroxide solution, the carbon dioxide and sulfur dioxide produced by reactive species are eliminated. The reaction mechanism shown in the image below indicates that only compounds 1 and 2 produce only one product.
Answer:
electric balance, goggles, beaker
Explanation:
I did it and got it right
Answer:
D) a salt bridge
Explanation:
A salt bridge completes an electrochemical cell. A salt bridge maintains charge balance in the two half cells. If the salt bridge is not present, the anode compartment becomes positively charged while the cathode compartment becomes negatively charged hence the reaction reaches equilibrium and comes to a halt quickly.
Rocks. Because the air water and soil are part of carbon.
