This reaction is known as
Acidic Cleavage of Ether.
Ether when treated with strong acid like
HI, the oxygen atom of ether picks the proton making a positive charge on oxygen. The
Iodide conjugate base formed acts as a
nucleophile and attacks on the carbon next to positive oxygen and forms
Alkyl Halide. This is a type of
SN² reaction. The complete reaction with missing atoms, charges and arrows is shown below,
Answer:
Oxygen gas
Explanation:
Given expression:
CH₃CH₂OH + 3O₂ → 2CO₂ + 3H₂O
Number of moles of oxygen gas = 1 mole
Number of moles of ethanol = 1 mole
Unknown:
The limiting reactant = ?
Solution:
The limiting reactant is the reactant in short supply in a chemical reaction. To find this specie, we always us the number of moles.
From the equation of the reaction:
1 mole of ethanol would require 3 moles of oxygen gas
But we have been given just 1 mole of oxygen gas instead of 3moles.
Therefore, oxygen gas is the limiting reactant.
Answer:
The answer to your question is 12
Explanation:
Data
Number of electrons in Phosphorus 3+ ion
Process
1.- The sign of the number after the name indicates if the element has lost or gained electrons.
If the sign is positive the element has lost electrons
If the sign is negative the element has gained electrons.
2.- Phosphorus atomic number is 15, then the number of electrons in Phosphorus 3+ will be 12, in this example, Phosphorus lost 3 electrons.
