5. Chemical change The heat from the oven causes the properties of the cookies to change When the cookies bake, the color changes to golden-brown and the chocolate chips are still visible after they’ve been mixed with the batter.

6. Physical change Mix Crisco, brown sugar, milk, and vanilla where there is no evidence of the different ingredients. Must be mixed well. Because none of the ingredients can be seen, this is a physical change.

7. An ionic compound involved Crisco Shortening has Triglyceride C 55 H 98 O 6 Ions

8. A covalent compound involved Sucrose C 12 H 22 O 11 Polar

9. Stoichiometry ¾ cup (3/4 stick) Crisco Shortening 1 ¼ cups firmly packed light brown sugar 2 tbsp. milk 1 tbsp. vanilla 1 egg 1 ¾ cups all-purpose flour 1 tsp. salt ¾ tpsn. baking soda 1 cup semi-sweet chocolate chips 30 servings ×.625 ÷ 36 servings
