9. Fischer projections are primarily used to represent carbohydrates, which contain multiple stereocenters. The structure of carbohydrate D-glucose is shown below as a Fischer projection with each carbon numbered. For each carbon, find the absolute configuration ( \( R \) or \( S \) ) if it is a stereocenter, or indicate that it is not a stereocenter. Completely fill in the circle in front of your chosen answer. 10. Xylitol is found in fruit and is used as a sugar substitute. (a) Use the given template to redraw the given structure as a Fischer projection. The numbered carbon atoms in the line structure must correspond to the numbered carbons in the Fischer projection. Make sure you fill in the end of every bond in the template, one position has been filled for you. (b) Determine whether xylitol is chiral or achiral. Completely fill in the circle in front of your chosen answer. (b) Xylitol is:
