In 1864, the Solvay process was developed to make soda ash. One step in the process is represented by the balanced equation below.

NaCl + NH3 + CO2 + H2O → NaHCO3 + NH4Cl

Write the chemical formula for one compound in the equation that contains both ionic bonds and covalent bonds. Explain, in terms of electronegativity difference, why the bond between hydrogen and oxygen in a water molecule is more polar than the bond between hydrogen and nitrogen in an ammonia molecule. In the space in your answer booklet, draw a Lewis electron-dot diagram for the reactant containing nitrogen in the equation.

Josephine Brown · Answer 1

NaHCO3 has an ionic bond between Na and HCO3 and a covalent bond between HC and O3.

The greater the electronegativity difference the more ionic a bond will be, Oxygen and Hydrogen have a considerably big electronegativity difference as compared with between Hydrogen and Nitrogen.
