HELP PLS !! Hypothesis: Before you begin, predict how many compounds you can make from the elements below. Pick one element from the metal list and two from the nonmetal list.

For example, "If I use sodium, hydrogen, and oxygen, then I can make ten new compounds in five minutes."

Now, you try! Make a prediction. Be sure to record your prediction on your lab report.

Metal

• Sodium (Na)

• Calcium (Ca)
Nonmetal
• Hydrogen (H)

• Oxygen (O)

• Carbon (C)

• Chlorine (Cl)

Janel’s class studied properties of matter and how matter can change. janel decided she would do an experiment mixing baking soda and vinegar. question: describe the properties of baking soda and vinegar, and explain the changes that janel should see when she mixes the two types of matter. •first, identify the physical state of matter of baking soda. describe another property of baking soda. •next, identify the physical state of matter of vinegar. describe another property of vinegar. •then, explain what janel should see when she mixes the baking soda and vinegar. •describe the states of matter of the new materials that are formed. •explain how janel can be certain a change has occurred. me
