IM HAVING TROUBLE WITH THESE
16. Assign oxidation numbers to each element in the compound. Type your answers in the space below. Make sure to identify if each is positive or negative.
KNO3
17. Metal alloys are materials used for building strong, sturdy structures; however, exposure to outside elements over time can weaken them. Explain WHAT happens and HOW this happens.
18. How can we maintain the integrity of metal objects and prevent corrosion?
19. Compare and contrast voltaic versus electrolytic cells.

Ithink that the use of creativity in the sciences entails that one produce something out of nothing or from another thing. with this, i think that the he wrote down his results as four parts of the atomic theory is the manifestation of the  creativity of john dalton.
