The answer is 40.0 atomic number .
Answer:
Reaction follows frieldel-craft alkylation mechanism
Explanation:
- Reaction between benzene and chloroform in the presence of
follows friedel-craft alkylation of benzene - Firstly, one equivalent of benzene adds onto chloroform by replacing one equivalent of Cl from chloroform.
- Remaining two equivalent of Cl in chloroform are similarly replaced by two equivalent of benzene to produce triphenylmethane
- Reaction mechanism has been shown below
The answer is the last one .... The ability to do work and cause change
The process that is physical changes is:
- mixing frozen orange juice concentrate with water
<h3>What is a physical change?</h3>
A physical change can be described as a type of change that take place in physical without chemical reaction as opposed to chemical change.
They are changes that are usually reversible it should be noted that physical change do not involve the alterations as regards the chemical make up of a particular substance and as a result of this , in physical change, there is no formation of new product.
Therefore, The process that is physical changes is mixing frozen orange juice concentrate with water
