Deuterium oxide, D20, is water that contains the stable hydrogen isotope H, usually shown as D. When dissolved in deuterium oxide, ethanol undergoes the following reaction: CH3CH2OH + D2O → CH;CH2OD + HOD What is the best way of showing that this reaction has occurred? A. By testing the product with phosphorus pentachloride and not getting steamy fumes. B. By determining the mass spectrum of the mixture and showing peaks at m/z values of 20 and 46. C. By fractionally distilling the mixture and determining the amount of CH3CH2OD using a Geiger counter. D. By determining the mass spectrum of the mixture and showing peaks at m/z values by 19 and 47.

How does a chemical reaction obey the law of conservation of matter? A C D The same number of molecules appear in the reactants as appear in the products. The total mass of the reactants is equal to the total mass of the products. The same total number of chemical bonds are in the reactants as are in the products. The same number of reactant particles as product particles are in- volved in the reaction.
When a chemical reaction occurs, atoms rearrange to form now compounds, but no new atoms are created nor are any destroyed This concept is called conservation of mass. Mass conservation can be seen in a balanced chemical equation where the numbers of each kind of atom are the same on both sides of the reaction arrow. The figure (Figure 1) shows the reaction of element A (lavender spheres) with element B (tan spheres). Write the balanced chemical equation for this reaction in terms of A and B. Express your answer as a chemical equation. When balancing chemical equations with polyatomic ions, it may help to balance the ion as a whole. For example, the ion PO_4^3 can be treated as a unit and balanced in both the reactants and the product, or you can break it down and balance each atom separately.
