Whats the question? I need to know to help....
Answer:
Concentration of ethanol required = 48.476 M
Explanation:
Given that:
the absorption intensity = 1.00
Molarity of ethanol = 1M
NMR instrument used = 160 MHz
Temperature used = 300 K
The required concentration of ethanol can be determined as follows:
= 48.476 M
Answer:
Decomposition or cracking
Explanation:
Decomposition reaction is a chemical change in which a single compound is broken down into two or more simpler products.
For example;
A → B + C
The driving force of such reaction is the high positive heat of formation of the compound which indicates that they are highly unstable.
Some stable compounds also decompose when subjected to high temperature and pressure.
