In this question, we need to state the chemical formula for the iron-containing ore hematite. Let's first describe the element iron, which is extracted from iron ores. Iron is element number 26 on the periodic table. Its atomic number of 26 tells us that an atom of iron has 26 protons in its nucleus.
