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.
Explanation:
Hello!
In this case, since the main molecular reaction that is taken place in the beaker is:
In such a way, we understand that one breaker contained silver nitrate and the other one barium iodide. Thus, the complete molecular equations turns out:
Now, for the complete ionic equation, we just ionize the aqueous species:
Finally, for the net ionic equation we cancel out barium and nitrate ions as the spectator one because they are both sides on the equation:
