Label each statement with its corresponding type of scientific knowledge. law theory fact hypothesis the melting point of ice is 0°c. repeated observations have consistently shown that oppositely charged objects attract each other. when the elements carbon and nitrogen are mixed at 1500°c, they will react with each other. atoms are made of protons, neutrons, and electrons. although we can’t directly see these particles, this structure explains many experimental observations.
