Equations for the Formation of Oxides from Simple Substances

The equations you provided represent the formation of oxides from simple substances. Let's go through each equation and explain the reaction and products.

A. 2CO + O2 = 2CO2 This equation represents the reaction between carbon monoxide (CO) and oxygen (O2) to form carbon dioxide (CO2). In this reaction, two molecules of carbon monoxide combine with one molecule of oxygen to produce two molecules of carbon dioxide.

B. N2 + O2 = 2NO This equation represents the reaction between nitrogen gas (N2) and oxygen gas (O2) to form nitrogen monoxide (NO). In this reaction, one molecule of nitrogen gas reacts with one molecule of oxygen gas to produce two molecules of nitrogen monoxide.

C. CH4 + 2O2 = 2H2O + CO2 This equation represents the combustion of methane (CH4) in the presence of oxygen (O2). Methane reacts with two molecules of oxygen to produce two molecules of water (H2O) and one molecule of carbon dioxide (CO2).

D. 2H2 + O2 = 2H2O This equation represents the reaction between hydrogen gas (H2) and oxygen gas (O2) to form water (H2O). In this reaction, two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of water.

These equations represent different chemical reactions where simple substances combine to form oxides. The reactants on the left side of the equation combine and rearrange their atoms to form the products on the right side of the equation.
