Is steel wool + fire = Iron Oxide a chemical reaction

The blackbody curve for a star name zeta is shown below. what is the peak wavelength for this star ?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.

Use the periodic table to determine how many grams of oxygen would be required to react completely with 859.0 g c2h2
