select two of the following compounds that are covalent.\na. cacl₂\nb. p₂o₅\nc. fe₂s₃\nd. mgf₂
Answer
Brief Explanations:
Covalent compounds are formed by the sharing of electrons between non - metal atoms. In $CaCl_2$, calcium (a metal) and chlorine (a non - metal) form an ionic compound. In $P_2O_5$, both phosphorus and oxygen are non - metals and share electrons to form a covalent compound. In $Fe_2S_3$, iron (a metal) and sulfur (a non - metal) form an ionic compound. In $MgF_2$, magnesium (a metal) and fluorine (a non - metal) form an ionic compound.
Answer:
B. $P_2O_5$
