Answer:
The isotope notation for an ion of silver-109 with a charge of positive 1 is .
Explanation:
The elements with same atomic number with different mass numbers are called isotopes.
The isotopes of silver is as follows.
From the above two isotopes have same atomic number and different mass number.
From the given,the isotope notation for an ion of silver-109 with a charge of positive 1
It can be represented is as follows.
General representation of isotope is as in attachment.
Answer:
See explanation below
Explanation:
This is a reaction of alkyne hydration. We have aqueous sulfuric acid in HgSO4. This reagent is used to convert a alkyne into a ketone. The mechanism of reaction is taking place in 4 steps.
The first step is an electrophilic adition where the atom of Hydrogen that the acid provides, is added to the alkyne in the triple bond.
In this step, as Carbon 2 and Carbon 3, do not have any atom of hydrogen, the adition of this hydrogen could take place in either carbon 2 or carbon 3, that's why at the end you can have two products in equal amounts.
The second step is the adition of one molecule of water in the carbocation that appears in the previous step.
The third step, is an acid base equilibrium, where the hydrogen atom from the water that added to the heptene, is substracted (In this case by the conjugate base of the acid).
In this way, we will have an alcohol with a double bond. This is the enolic form of the molecule.
The final step is a tautomeric equilibrium, where the double bond of the C = C will pass to a double bond C = O forming a carbonile and therefore, a ketone.
If this was done in carbon 2 from step 1, you'll have the 2-heptanone. If it were on carbon 3, it will be the 3 - Heptanone.
Picture attached has the mechanism and products.
