The balanced net ionic equation for the reaction of Sn 2 + with Cr 2 O 7 2 − in an acidic solution is to be written, the number of grams of tin in the alloy sample and the percentage by mass of tin in the solder are to be calculated. Concept Introduction: The reactions in which the addition of oxygen atoms or the removal of hydrogen atoms takes place are known as oxidation reactions. The reactions in which the addition of hydrogen atoms or the removal of oxygen atoms takes place are known as reduction reactions. The chemical reactions in which one reactant gets oxidized while the other gets reduced during the reaction are called the oxidation-reduction reactions or the redox reactions. Stoichiometry involves calculations on reactants and products and considers the total mass of the reactants to be equivalent to the total mass of the products.

Shown below are five NMR spectra for five different C6H10O2 compounds. For each spectrum, draw the structure of the compound, and assign the spectrum by labeling H's in your structure (or in a second drawing of the structure) with the chemical shifts of the corresponding signals (which can be estimated to nearest 0.1 ppm). IR information is also provided. As a reminder, a peak near 1700 cm-1 is consistent with the presence of a carbonyl (C=O), and a peak near 3300 cm-1 is consistent with the presence of an O–H.
Extra information: For C6H10O2 , there must be either 2 double bonds, or 1 triple bond, or two rings to account for the unsaturation. There is no two rings for this problem.
A strong band was observed in the IR at 1717 cm-1
