Question
researchers are considering using dimethyl ether (ch₃och₃) as an alternative to diesel fuel. dimethyl ether and water (h₂o) are produced when methanol (ch₃oh) is heated in the presence of a catalyst. this chemical reaction is represented by the model below. determine the number of each type of atom in the reactants and products. number of atoms in reactants number of atoms in products h c 2 2 o
Step1: Count H atoms in reactants
Each \(CH_3OH\) molecule has \(4\) H atoms. There are \(2\) \(CH_3OH\) molecules (reactants). So \(4\times2 = 8\) H atoms.
Step2: Count H atoms in products
In \(CH_3OCH_3\), there are \(6\) H atoms and in \(H_2O\) there are \(2\) H atoms. So \(6 + 2=8\) H atoms.
Step3: Count O atoms in reactants
Each \(CH_3OH\) molecule has \(1\) O atom. There are \(2\) \(CH_3OH\) molecules. So \(1\times2 = 2\) O atoms.
Step4: Count O atoms in products
In \(CH_3OCH_3\), there is \(1\) O atom and in \(H_2O\) there is \(1\) O atom. So \(1+1 = 2\) O atoms.
