Question

Выберите формулы соединений, в которых химические связи: а) ковелентные неполярные; б) ковалентные полярные; в) ионные. H2, HBr, Na2O, CaO, Co2, CO, O2, NO2, K3N, NH3, N2. NF3, f3, OF2, MgF2.

Answer 1

А:H2, O2, N2, F3

Б:HBr, CO2, CO, NO2, NH3, NF3, OF2

В:Na2O, CaO, K3N, MgF2

Answer 2

Covalent Nonpolar Bonds:

- H2 - N2

Covalent Polar Bonds:

- HBr - CO - NO2 - NH3 - NF3 - OF2

Ionic Bonds:

- Na2O - CaO - K3N - MgF2

Please note that the above information is based on the chemical nature of the compounds and the type of bonds they form. Covalent nonpolar bonds occur when two atoms share electrons equally, while covalent polar bonds occur when the electrons are shared unequally. Ionic bonds occur when there is a complete transfer of electrons from one atom to another, resulting in the formation of ions.
