A chemical reaction is a reaction that forms a new substance and it is also a reaction that s permanent ( you cannot reverse)
The answer would be 1952.5 grams of potassium sulfate solution. The way to get the answer is to use the equation, 617/x = 31.6%/1 and then cross multiply to get 31.6%x= 617grams and then 0.316x=617 grams so then x = 617/0.316= 1952.5 grams.

Group 7A
Explanation:
The group 7A elements consists of the most reactive non-metals on the periodic table.
This group is known as the group of halogens. They consist of element fluorine, chlorine, bromine, iodine and astatine.
- The elements in this group have the highest electronegativity values.
- They have 7 valence electrons and requires just one electron to complete their octets.
- This way, they are highly reactive in their search for that single electron.
