Question

what is the name of nacl *
sodium chloride
sodium chlorine
sodium (i) chloride
sodium dichloride
what is the formula for iodine pentafluoride? *
if
if5
i5f
i2f5
which of these compounds is most likely covalently bonded? *
nacl
mgo
co2
kbr

Explanation:

1. NaCl is an ionic compound formed by sodium (Na⁺) and chloride (Cl⁻) ions, and its name is Sodium Chloride.
2. In Iodine Pentafluoride, "penta -" indicates 5 fluorine atoms bonded to 1 iodine atom, so the formula is IF₅.
3. Covalent bonds usually form between non - metals. CO₂ is composed of non - metals carbon and oxygen, while NaCl, MgO, and KBr are ionic compounds formed between metals and non - metals.

Answer:

1. A. Sodium Chloride
2. B. IF5
3. C. CO2
