Question

match each molecule with its atomic model. ethane (c₂h₆) methane (ch₄) water (h₂o)

Explanation:

Ethane ($C_2H_6$) has two carbon - atoms bonded together with hydrogen atoms attached. Methane ($CH_4$) has a single carbon atom with four hydrogen atoms bonded to it. Water ($H_2O$) has an oxygen atom with two hydrogen atoms bonded to it. Match based on the number of atoms and their bonding patterns.

Answer:

Ethane ($C_2H_6$) - top atomic model; Methane ($CH_4$) - middle atomic model; Water ($H_2O$) - bottom atomic model
