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.
The heat energy needed is 2928800J. Mass is given as 20 (kg)
Explanation:

The question is a bit confusing but here i go..
Carbon (after hydrogen, helium and oxygen).
Answer:
32.5% female
67.5% male
Explanation:
To find a percentage, you need your total.
To find your total, add the amount of men and the amount of women.
240 total people were enrolled in chemistry at that high school.
Next, to solve for your percentage of female participants, divide the amount of women by your total.
32.5% were women. Do the same with your male participants for your male percentage.
67.5% were men.
