Draw three possible resonance structures for H,SO, in your notebook. Use the octet rule and formal charges to evaluate your resonance structures and determine how many bonds would likely occur in the resonance hybrid. Drag the numbers that represent your best estimate for the two H-O bonds and the three 0-s bonds into the gray boxes below. HO 10 ISO

Answer the following questions about the Lewis structure for calcium hydrogen carbonate, Ca(HCO3)2 There are calcium ions and hydrogen carbonate ions. There are ionic bonds in the molecule. The calcium ion has electron dots. Each hydrogen carbonate ion has central atoms and valence electrons. Each hydrogen carbonate ion has single covalent bonds, double covalent bonds, and triple covalent bonds. In each hydrogen carbonate ion, the central C has REDS, the shape is y and the bond angles are about In each hydrogen carbonate ion, the central O has REDS and the shape is а.
