I found the recipe online. It looked really good.The pure substances are baking soda, salt, and sugar.The homogeneous mixtures are all purpose flour, ground cinnamon, and confectioners’ sugar. The heterogeneous mixtures are eggs, the ground cloves, and ground nutmeg. Adding the icing is a physical change and shaping the cookies are physical changes.The cookies rising is a sign of a chemical change and another chemical change is the browning of the cookies.
