CHEMICAL CHANGES AND THERMOCHEMISTRY.

MATERIALS: EQUIPMENT:

• Test tubes
• Measuring cups
• pH measuring strip
• Goggles
• Lab coat & gloves

CHEMICALS:

• KOH (potassium hydroxide)
• CaCl2 (calcium chloride)
• Baking soda
• H2O

FIRST EXLERIMENT: MATERIALS

• Calcium chloride
• Baking soda
• Water

1ST EXPERIMENT PROCEDURE:

• Test tube with calcium chloride and measuring cup with baking soda. We need to tell how much baking soda measured with teaspoon
• Measuring cup with 10 ml of water.

EXPERIMENT 2

• Calcium chloride is combined with baking soda
• You cant recognize which is which because they
• Look the same. When you shake it a smoke
• Comes out it is exothermic because heat is
• Coming out.ph was eleven lightly to burn.
