Look at the Lewis structure you drew for NH3 and H2CO. Both of these molecules are made up of four atoms. Do they ave the same molecular geometries? O Yes DNo

Which of this molecules or ions not a tetrehedral molecular structure? PO4-3 SO4-2 NI+ CH4 HClO3 I drew the lewis dot structure of each but they all seem to be tetrehedral to me. Please tell me the correct answer and why.

For which two molecules would you expect deviation from ideal bond angles? Ideal bond angles are angles you would expect from electron's geometry (i.e: Tetrahedral ideal bond angle is 109.5°) O H20 PCI5 SF6 O SO2

Which of the following statement(s) is/are TRUE regarding NO and NO₂? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a The nitrogen atom in NO₂ has one more lone pair of electrons than the nitrogen atom in NO. b с d The average N-O bond order in NO₂ is 3/2. The average formal charge on O in NO is -1/2. The average N-O bond order in NO₂ is 3/2.

In the correct Lewis Structure for CH4, how many lor e pairs (unshared pairs) are on the central atom? Give all atoms zero formal charge, C in middle surrounded by H (You can use my easy method for molecules containing C,H,0,N F only if you want) O 1 O 2 O 3 O 4 O 5 O 6 es

7. Determine the molecular shape for SO3  ? Z of S =16,  O = 8 a.octahedralb.trigonal pyramidalc.T-shaped.trigonal planar

What are the angles a and b in the actual molecule of which this is a Lewis structure? H = 0° b = 0° a a = CEN: Note for advanced students: give the ideal angles, and don't worry about small differences from the ideal that might be caused by the fact that different electron groups may have slightly different sizes. b X S
