Identify the covalent compounds based on the names of the compounds. barium nitrate dinitrogen tetroxide boron trifluoride ammon
noname [10]

Covalent compounds are composed of atoms that are linked via covalent bonds i.e. bonds formed by mutual sharing of electrons. This is in complete contrast to ionic compounds which are held together by ionic bonds, i.e. bonds formed by complete transfer of electrons from one atom to the other.

In the given examples we have:

Barium nitrate: Ba(NO3)2 - Ionic

Dinitrogen tetroxide: N2O4- Covalent

Boron trifluoride: BF3-Covalent

Ammonium sulfate: (NH4)2SO4- Ionic

Carbon tetrachloride: CCl4- Covalent

Barium chloride: BaCl2 - Ionic

Gnom [1K]
<span>The molecular formula that describes the problem is
2CH3COOH (aq) + Ca(OH)2 (s) ---> Ca(CH3COO)2 (aq) + 2H2O (l)

The net equation is written as follows:
2CH3COOH- (aq) + 2H+ (aq) + Ca(OH)2 (s) ---> Ca2+ (aq) + 2 CH3COO- (aq) + 2H2O (l)
canceling out spectator ions
2H+ (aq) + Ca(OH)2 (s) ---> Ca2+ (aq) + 2 H2O (l)</span>
