Chemical reactions involve the breaking of chemical bonds, the rearrangement of elements, and the formation of new bonds. In order for a chemical reaction to take place, the particles must collide. The collision between the molecules in a chemical reaction provides the needed to break the necessary bonds so that new bonds can be formed. Successful collisions result in a chemical reaction that or energy. If the products have lower energy than the reactants, the reaction is and energy is If the reactants have lower energy than the products, the reaction is and energy is

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
