Maya made this picture to represent a chemical reaction: There are two overlapping circles on the left, one white and the other with vertical lines. It is labeled ZX. There is a gray circle labeled Y on the right of ZX. There is a plus sign between ZX and Y. An arrow pointing right is shown on the right of the gray circle labeled Y. Two overlapping circles, one white and the other gray are shown on the right of the arrow and is labeled XY. On the right of XY there is a small circle with vertical lines labeled Z. There is a plus sign between XY and Z. Which of the following statements best explains the type of chemical reaction represented by Maya's picture? It is neither a synthesis reaction nor a decomposition reaction because the total mass of the products is less than the total mass of the reactants. It is neither a synthesis reaction nor a decomposition reaction because two reactants form two products. It represents a synthesis reaction because the same atoms are present in the reactants and products. It represents a decomposition reaction because two reactants break apart and form two products.
