The chemical symbol for dihydrogen monoxide is H2O. However, it seems like there might be some confusion or inside joke surrounding this term among your classmates. Dihydrogen monoxide is actually the chemical name for water. The term "dihydrogen" refers to two hydrogen atoms, while "monoxide" refers to one oxygen atom, which is the chemical composition of water. It appears your classmates might be engaging in some humorous or light-hearted banter surrounding this fact.
