1. Calculate the number of moles of O2 produced using the ideal gas law. Then, use this value to calculate the number of moles o
f hydrogen peroxide you began the experiment with. HINT: Use the balanced equation provided in the lab introduction. 2. Calculate the number of moles of hydrogen peroxide you would have if you used 5 mL of a pure hydrogen peroxide solution. HINT: The density of hydrogen peroxide is 1.02 g/mL. 3. Determine the percentage of hydrogen peroxide in your solution. 1.02 g/mL * 5 mL = 5.1g / 34 g = 0.15 mol 4. Was the calculated percentage of hydrogen peroxide close to the same as the percentage on the label (3%)? Calculate percent error of your value.

Answer: The bonds are intermediate between double and single bonds
Explanation:
A closer look at the diagram below shows that the bonds in sulphur IV oxide are intermediate between double and single bonds. Hence they do not have the exact bond angle of single bonds. This is why the bond angle is not exactly 120°. There are two resonance structures in the diagram that clearly show this point.
