Respuesta :
at Standard Temperature and Pressure Carbon monoxide (CO), carbon dioxide (CO2) and nitrogen dioxide (NO2) exist as gases
Option C is correct
Low molecular weight covalent compounds
Covalent compounds are compounds that are characterized by strong Intra-molecular bonds and they are solids as they have higher molecular weights
But when compounds like Carbon monoxide (CO), carbon dioxide (CO2), and nitrogen dioxide (NO2) are formed with low molecular weight covalent bonds They exist as gases
