What is the structural formula for methane and ethane?  LINEAR form for both. Thanks

Which of these statements correctly describes the relationship between the displayed molecules? -Only one of these represents a valid Lewis Structure -They do not have the same molecular formula -They are isomers -They are the same molecule

To answer the questions, interpret the following Lewis structure for SO42-. For the central sulfur atom: ... The number of lone pairs =   The number of single bonds =   The number of double bonds = The central sulfur atom: obeys octet rules or expanded octet rules or has incomplete octet rules? 2) To answer the questions, interpret the following Lewis diagram for  CO2 .For the central carbon atom:  ... The number of lone pairs =   The number of single bonds =   The number of double bonds = The central carbon atom: obeys octet rules or expanded octet rules or has incomplete octet rules?   3) To answer the questions, interpret the following Lewis structure for BCl3. For the central boron atom: ... The number of lone pairs =   The number of single bonds =   The number of double bonds = the central boron atom: obeys octet rules or expanded octet rules or has incomplete octet rules?

help por favor I just need to draw the molecule
