A gate made of painted iron is beginning to rest in areas where the paint has worn away why is the formation of rust considered a chemical change? A. oxygen in the air combines with the paint, forming a new compound that has the same properties as iron but a different arrangement of atoms.

B. Oxygen in the air combines with the exposed iron, forming a new compound that has properties different from iron.

C. The paint reacts with the iron beneath it and causes rust to form, changing the chemical properties of the iron.

D. The paint reacts with oxygen in the air and causes rust to form, changing the chemical properties of the iron.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

the correct answer would be d. hope this !

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
