Question

The table shows a list of compounds that are gases at stp identify the type of bonding (ionic, covalent, or metallic) for each compound listed

hydrogen sulfide (H2S)
Ammonia (NH3)
Methane (CH4)
Nitrous Oxide (N2O)

Answer 1

All of the compounds listed above have covalent bonding.

according to science direct,

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei.

all of the compounds above share 1 or more pairs of electrons.

Answer 2

hydrogen sulfide (H2S): covalent

Ammonia (NH3): covalent

Methane (CH4): covalent

Nitrous Oxide (N2O): covalent

Step-by-step explanation:

o Hydrogen sulfide (H2S is a covalent compound that is composed out of 2 hydrogen atoms.

o Because one nonmetal combines with another nonmetal to form a covalent compound, ammonia (NH3) is a covalent compound.

o CH4 (Methane) is a covalent (nonpolar covalent) compound because when two nonmetals combine, they form a covalent compound.

o Nitrous Oxide (N2O) is a covalent bond. Since the N-N-O bond angle is 1800, the central N makes one covalent bond with N and O.
