Answer to Problem 27E

The compound N2H4 is covalent.

Explanation of Solution

Given Info: The compound is N2H4 .

Explanation:

A covalent bond is formed when electron pairs are shared by two atoms. A covalent bond is formed when two nonmetals combine or compounds that are gases, liquids or have low melting points.

Ionic bonds are formed by electrostatic interactions between an electropositive and electronegative atom. An ionic bond forms when a metal and a nonmetal combine or a metal combines with polyatomic anions.

In the compound N2H4 , nitrogen and hydrogen are nonmetals. Therefore, N2H4 is a covalent compound.

Conclusion:

Therefore, the compound N2H4 is covalent.

Answer to Problem 27E

The compound (NH4)3PO4 is ionic.

Explanation of Solution

Given Info: The compound is (NH4)3PO4 .

Explanation:

A covalent bond is formed when electron pairs are shared by two atoms. A stable covalent molecule is formed only when the octet rule is followed for the atoms which share electron pairs. A covalent bond is formed when two nonmetals combine or compounds that are gases, liquids or have low melting points.

Ionic bonds are formed by electrostatic interactions between an electropositive and electronegative atom. An ionic bond forms when a metal and a nonmetal combine or a metal combines with polyatomic anions.

In the compound (NH4)3PO4 , ammonium is polyatomic cation and phosphate is a polyatomic anion. Therefore, (NH4)3PO4 is an ionic compound.

Conclusion:

Therefore, (NH4)3PO4 is an ionic compound.
