Question

two models of the same compound are shown. c₂h₄o₂ model a model b in what way is model b better than model a? model b shows the types of elements in the compound, but model a does not. model b shows the three - dimensional shape of the molecule, but model a does not. model b shows how the atoms in the molecule are connected, but model a does not. model b shows the number of atoms of each element in the molecule, but model a does not.

Explanation:

Model A is a molecular - formula representation ($C_{2}H_{4}O_{2}$) which only shows the number of atoms of each element. Model B is a structural - formula representation which shows how the atoms in the molecule are connected.

Answer:

Model B shows how the atoms in the molecule are connected, but Model A does not.
