Remembering the periodic table, Fe is iron and O is oxygen. The elements that combine to create rust are iron and oxygen, with the chemical compound being (Iron)2(Oxygen)3.
The answer is C. The specific amount of energy emitted when electrons jump from excited states to the ground state refers to emission spectrum. The energy is emitted in the form of photons, and the photons have very specific wavelengths (energy) that correspond to the energy gaps between the excited states and the ground state. The specific wavelengths of light emitted are referred to as the "emission spectrum," and each element produces a different emission spectrum. Thus, this emitted energy can be used to identify the element from which your sample was taken.

Answer:
naphthalene aka mothball sublimes
Answer:
22420g
Explanation:
Iridium is 22.42 grams for every one milliliter. We have 1000 millilitres, so 1000 x 22.42 = 22420g of iridium.
Hope this helps, let me know if you have any questions :)
