Question
help guys please for this quiz
The molecular geometry of the CHF3 molecule is , and the molecule is tetrahedral, nonpolar trigonal pyramidal, polar seesaw, polar seesaw, nonpolar tetrahedral, polar The F-B-F bond angle in the BF3 molecule is 109.5degree 60degree 180degree 90degree 120degree The molecular geometry of the H3O+ ion is octahedral trigonal pyramidal tetrahedral bent V linear According to VSEPR theory, if there are three electron domains on a central atom, they will be arranged such that the angles between the domains are 109.5 degree 120 degree 360 degree 90 degree 180 degree A covalent bond between the same two atoms is the longest. Quadruple single double triple They are all the same Using the table of bond dissociation energies, the Delta H for the following reaction Kl. 2HC1 (g) + F2 (g) rightarrow 2HF (g) + Cl2 (g) 223 208 -359 -223 359 How many equivalent resonance forms can be drawn for S02 without expanding octet on the sulfur atom (sulfur is the central atom)? 0 2 3 4 1
