(2 points) Develop Lewis structures for CH4,NH3, and H2O Build models for each molecule. (Use black sphere to represent C/N/O; white sphere to represent H). Make a three-dimensional drawing of each molecule based on your model. electron group distribution around central atom in each molecule CH4 NH3. .H2O. Molecular shape around central atom of each molecule CH4 NH3. H2O Predict the HXH(X=C/N/O) bond angle for each molecule CH4 NH3 H2O
