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:
The answer to your question is 49.08 u
Explanation:
Data
Average atomic mass = 45.737 u
Isotope 1 = 40.149 u abundance = 37.46%
Isotope 2 = ?
Process
1.- Calculate the abundance of isotope 2
abundance isotope 1 + abundance isotope 2 = 100%
37.46 + abundance isotope 2 = 100
abundance isotope 2 = 100 - 37.46
abundance isotope 2 = 62.54
2.- Calculate the mass of isotope 2
Average atomic mass = (abundance x mass isotope 1) + (abundance x
mass isotope 2)
45.737 = (0.3746 x 40.149) + (62.54 x mass isotope 2)
mass isotope 2 = [45.737 - (0.3746 x 40.149)]/ 62.54
mass isotope 2 = [45.737 - 15.0398]/ 62.54
mass isotope 2 = 30.6972/62.54
mass isotope 2 = 0.4908 x 100
mass isotope 2 = 49.08 u
The postulates of Dalton's theory were:
1) Elements are made of extremely small particles called atoms
2) <span>Atoms of a given element are identical in size, mass, and other properties
</span>3) <span>Atoms cannot be subdivided, created, or destroyed</span>
4) Atoms combine in whole number ratio to form compounds
5) Chemical reactions are the rearrangement of atoms
The third postulate has been disproved by modern science, in which the atom has been split and been subdivided into smaller parts such as the neutron, proton and electron, which are further subdivided into quarks, gluons, and kaons.
The second postulate was also disproved upon the discovery of isotopes.
Answer:
Percentage of mass of solute in aqueous phase is 28.57%.
Explanation:
- Fraction of solute in aqueous phase.
= Used volume of aqueous solution
= Used volume of organic solution
D = partition coefficient.
Mass of solute in aqueous phase = 
Therefore, Percentage of mass of solute in aqueous phase is 28.57%.
In this item, we are simply to find the ions that may bond and are able to form a formula unit. We are also instructed to give out their name. There are numerous possible combinations of ions to form a compound. Some answers are given in the list below.
1. Na⁺ , Cl⁻ , NaCl ---> sodium chloride (this is most commonly known as table salt)
2. C⁴⁺ , O²⁻ , CO₂ ---> carbon dioxide
3. Al³+ , Cl⁻ , AlCl₃ ----> aluminum chloride
4. Ca²⁺ , Cl⁻ , CaCl₂ ---> calcium chloride
5. Li⁺ , Br⁻ , LiBr ---> lithium bromide
