Answer:

Fluorine

Explanation:

Fluorine has an atomic number of 9

Iron's is 26

Phosphorus = 15

Potassium = 19

Fluorine has the smallest number of protons, and as it is an atom, the number of protons = the number of electrons. As it has less electrons, it only has 2 shells, whereas all the other elements here have 3+ shells. This means it will have a smaller atomic radius than them.

Hope this helps! Let me know if you have any questions :)

Sulfuric acid (h2so4) is spilled on a laboratory bench. which chemical would be useful for neutralizing the acid
marysya [2.9K]
Sulphuric acid (H2SO2) is a dibasic acid. It generated H+ ions when dissolved in water. In order to neutralize an acid, a base containing hydroxy ion (OH-) will be required. 

NaOH, Ca(OH)2, KOH, etc. can be used to neutralize H2SO4.

If NaOH is used as a base, following reaction is initiated.

2NaOH     +      H2SO4      →     Na2SO4     +     H2O     
 (base)                (acid)                  (salt)

When doing a recrystallization what observations would prompt
Volgvan
<h2>Observation of purified crystals.</h2>

Explanation:

  • Recrystallization is the process in which a compound is dissolved in a hot solvent and then allowed to cool which forms the crystals.
  • It is a technique used for purification of solids.
  • Recrystallization mainly depends on the solubility of the solvent that means the solid should be soluble in the solvent when it is hot and should be insoluble in the same solvent when it is cool.
  • The observations while doing recrystallization is to observe the purified crystals obtained and to filter it out.
