Baking powder is primarily used as a leavening agent in baked goods and products. It is a combination of cornstarch, cream of tartar and baking soda. The main observation that suggests that it is a mixture of substances is that fact that it produces a gas which facilitates the rising of the baked goods.
When the spring is stretched to 11.0 cm - 8.0 cm = 3.0 cm = 0.030 m away from equilibrium, it stores
1/2 (150 N/m) (0.030 m)² = 0.0675 J
of potential energy, while stretching it to 14.0 cm - 8.0 cm = 6.0 cm = 0.060 m from equilibrium stores
1/2 (150 N/m) (0.060 m)² = 0.27 J
Then the change in potential energy is 0.27 J - 0.0675 J = 0.2025 J ≈ 0.21 J
