The physical properties because when it is physically changed you can identify the change. In chemical changes it sometimes deals with chemicals and stuff that include the breaking of bonds with another element.
Answer:
Step 1) hydrolysis using NaOH/H2O to form benzylalcohol
Step2) oxidation to Carboxylic acid using KMnO4 followed by decarboxylation to form benzene
3) friedel craft acylation using CH3COCl/AlCl3
Explanation:
The above 3 steps will yield acetophenone from methylbenzoate
A : falling back to a it’s original lower state after being excited by fire.
Bomb calorimeters have to withstand the large pressure within the calorimeter as the reaction is being measured. Electrical energy is used to ignite the fuel; as the fuel is burning, it will heat up the surrounding air, which expands and escapes through a tube that leads the air out of the calorimeter.
Answer : The specify the l and ml values for n = 4 are:
At l = 0,
At l = 1,
At l = 2,
At l = 3,
Explanation:
There are 4 quantum numbers :
Principle Quantum Numbers : It describes the size of the orbital. It is represented by n. n = 1,2,3,4....
Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...
Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from . When l = 2, the value of will be -2, -1, 0, +1, +2.
Spin Quantum number : It describes the direction of electron spin. This is represented as The value of this is for upward spin and for downward spin.
As we are given, n = 4 then the value of l and ml are,
l = 0, 1, 2, 3
At l = 0,
At l = 1,
At l = 2,
At l = 3,
