Question

which compounds would you expect to form a covalent bond? select all that apply. k₂s cbr₄ h₂o mgo

Explanation:

Covalent bonds form between non - metals. In $K_2S$, potassium (K) is a metal and sulfur (S) is a non - metal, forming an ionic bond. In $CBr_4$, carbon (C) and bromine (Br) are non - metals, forming covalent bonds. In $H_2O$, hydrogen (H) and oxygen (O) are non - metals, forming covalent bonds. In $MgO$, magnesium (Mg) is a metal and oxygen (O) is a non - metal, forming an ionic bond.

Answer:

B. $CBr_4$, C. $H_2O$
