Two glasses of water have the same thermal energy. Must they have the same temperature? Explain
ira [324]
Even if two samples of matter have the same temperature, it does not necessarily mean they have the same total energy. The more particles a substance has at a given temperature, the more thermal energy it has.

Write the mechanism of the reaction of methyl benzoate to form methyl 2-nitrobenzoate.
Igoryamba
The question is incorrect, nitration of methylbenzoate occurs at 3 position to get, methyl 3-nitrobenzoate. 

This is because, in present reaction the reactant i.e. methylbenzoate, has low electron density at m-position.

Due to this, NO2+ prefentially attaches m-position to form  methyl 3-nitro benzoate as the product. 

A detailed reaction mechanism for formation of product is provided below.

What is the ph of with a 4.6 x 10-6 M hydroxide ion concentration?
Lunna [17]
<h3>Answer:</h3>

pH = 8.66

<h3>Explanation:</h3>
  • The pH refers to the acidity or alkalinity of a solution.
  • It is calculated by getting the negative logarithm of Hydrogen ions concentration.
  • pH=-log[H⁺]

In this case;

we are given [OH⁻] as 4.6 x 10^-6 M

We are required to calculate the pH

We need to know that;

pH + pOH = 14

pOH = -log[OH⁻]

To get the pH we can calculate the pOH first,

pOH = -log[4.6 x 10^-6 M]

        = 5.34

but, pH + pOH = 14

Therefore, pH = 14 - pOH

                        = 14 - 5.34

                        = 8.66

Therefore, the pH of the solution is 8.66
