The molecular structure of vitamin c (as you will see it in organic chemistry) is shown below. in the usual shorthand structure, each point where lines meet represents a c atom and most h atoms and lone pair electrons are not shown. draw the complete structure of the molecule, showing all c atoms, all h atoms, and lone pair electrons. indicate the hybridization of each c and o atom in the structure. determine the formal charge on each oxygen in the structure. if an h+ is lost from one of the oh groups, what will be the formal charge on the o that is left?

What is the relation between concentration of reactants and the rate of chemical reaction?

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes. which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature. sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent
