Finding the Odd One Out

To find the odd one out from the given options, let's analyze each set of compounds:

1) CO2, NO2, CO, K20, N2O 2) Na20, NO, SO2, P205, SO3 3) ZnO, BeO, SO2, CaO, Fe2O3 4) SiO2, SO2, CO2, NO2, NO

Let's examine each set in detail:

1) CO2, NO2, CO, K20, N2O - CO2 is carbon dioxide, a compound composed of one carbon atom and two oxygen atoms. - NO2 is nitrogen dioxide, a compound composed of one nitrogen atom and two oxygen atoms. - CO is carbon monoxide, a compound composed of one carbon atom and one oxygen atom. - K20 is potassium oxide, a compound composed of two potassium atoms and one oxygen atom. - N2O is nitrous oxide, a compound composed of two nitrogen atoms and one oxygen atom.

2) Na20, NO, SO2, P205, SO3 - Na20 is sodium oxide, a compound composed of two sodium atoms and one oxygen atom. - NO is nitric oxide, a compound composed of one nitrogen atom and one oxygen atom. - SO2 is sulfur dioxide, a compound composed of one sulfur atom and two oxygen atoms. - P205 is diphosphorus pentoxide, a compound composed of two phosphorus atoms and five oxygen atoms. - SO3 is sulfur trioxide, a compound composed of one sulfur atom and three oxygen atoms.

3) ZnO, BeO, SO2, CaO, Fe2O3 - ZnO is zinc oxide, a compound composed of one zinc atom and one oxygen atom. - BeO is beryllium oxide, a compound composed of one beryllium atom and one oxygen atom. - SO2 is sulfur dioxide, a compound composed of one sulfur atom and two oxygen atoms. - CaO is calcium oxide, a compound composed of one calcium atom and one oxygen atom. - Fe2O3 is iron(III) oxide, a compound composed of two iron atoms and three oxygen atoms.

4) SiO2, SO2, CO2, NO2, NO - SiO2 is silicon dioxide, a compound composed of one silicon atom and two oxygen atoms. - SO2 is sulfur dioxide, a compound composed of one sulfur atom and two oxygen atoms. - CO2 is carbon dioxide, a compound composed of one carbon atom and two oxygen atoms. - NO2 is nitrogen dioxide, a compound composed of one nitrogen atom and two oxygen atoms. - NO is nitric oxide, a compound composed of one nitrogen atom and one oxygen atom.

Based on the analysis, the odd one out is K20 in the first set (1). The other compounds in the set are all oxides or compounds containing oxygen, while K20 does not fit this pattern.
