Answer:
Fluorine.
Explanation:
Fluorine has more protons resulting in a greater nuclear charge, causing a greater attraction for electrons. ... Fluorine has a smaller radius than lithium because of the greater positive charge of the nucleus, pulling electrons and the electron shells in closer.

1) Both have molecules or atoms
2) Both occupy space and have mass
3) Both can be ionized
4) Solids conduct electricity similarly gas can also conduct electricity in discharge tube under low pressure
5) Both have densities
Answer:
Se pueden separar dos líquidos inmiscibles, aceite y agua, mediante el uso de un embudo de separación. La mezcla de aceite y agua forma dos capas separadas porque son completamente insolubles entre sí. El aceite forma la capa superior mientras que el agua forma la inferior.

Answer:
in theoretical yield are obtained 2.61 g of aspirin from 2.0 g of salicylic acid and 5 mL of acetic anhydride
Explanation:
Aspirin (C9H8O4)
∴ mm C9H8O4 = 180 g/mol
salicylic acid (C7H6O3)
∴ mm C7H6O3 = 138 g/mol
acetic anhydride (C4H6O3)
∴ mm C4H6O3 = 102 g/mol
acetic acid (C2H4O2)
∴ mm C2H4O2 = 60 g/mol
reaction:
- C7H6O3 + C4H6O3 → C9H8O4 + C2H4O2
∴ g C7H6O3 = 2.0 g
∴ g C4H6O3 = (5.0 mL)(1.08 g/mL) = 5.4 g
limit reagent (L.R):
∴ n C7H6O3 = (2 g)(mol/138 g) = 0.0145 mol C7H6O3 (L.R)
∴ n C4H6O3 = (5.4 g)(mol/102 g) = 0.053 mol C4H6O3 (E.R)
theoretical yield:
Amount of product predicted by balanced equation when all limit reagent reacts
⇒ n C9H8O4 = (0.0145 mol C7H6O3)(mol C9H8O4/mol C7H6O3) = 0.0145 mol C9H8O4
⇒ g C9H8O4 = (0.0145 mol)(180 g/mol) = 2.61 g C9H8O4
