Part C Follow these steps to complete the table:

Reuse the same test tubes from part B, labeled Fe2+ and Fe3+. Be sure they’re clean.
Add 4 milliliters of iron(II) sulfate to the test tube labeled Fe2+.
Add 4 milliliters of iron(III) nitrate to the test tube labeled Fe3+.
Add 4 milliliters of potassium permanganate to each test tube.
Observe the contents of the test tubes for about 10 minutes. Record your observations, noting any evidence of a chemical reaction. If there is no evidence of a reaction, write “no reaction.”

Contained in chromosomes which are located in the nucleus of the cell.

Molarity is moles of solute over liters of solution. idk if that is what you are talking about, but you can convert moles of solute to grams of solute using dimensional analyzes by using molar mass found on the periodic table.

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it

The answer to your q it is d
