Ok here's the question, My wife is in an Organic Chemisty 2 Lab, it has been over a year since she has had any chemistry and she is, by no means, a chemistry major. She is working on some homework and is quite frustrated. I have no had chemistry in over 4 years (since high school) and can not remember the formulas to help her. Here is the page she is working on: www.loudambiance.com/help.png

I do not want answers to the blanks, simply to be pointed in the direction of the formulas to get the answers. I thought i would be able to help her, but I got totally confused in the step from Sucrose to Glucose and Fructose due to the gain of 2H and 1O. I was always taught that a material in the catalyst is not transfered into the product. Any help would be great, thanks.

The "extra" two hydrogens and one oxygen formall equate to one molecule of water (H₂O). If you hydrolyse (cleave with the addition of water) sucrose you clip it in the middle to get fructose and glucose.

you know that the catalyst is conc HCl to initiate hydrolysis of sucrose only it protonates the sugar and the water exits as a product
