Final answer:
1) The bonding in nitrogen oxide is covalent because both nitrogen and oxygen are nonmetals. 2) OF2 forms a molecular crystal. 3) The equation for the reaction between OF2 and steam is OF2 + H2O → O2 + 2HF.
Step-by-step explanation:
1) The bonding in nitrogen oxide (NO) is covalent rather than ionic because both nitrogen and oxygen are nonmetals, and covalent bonds typically form between nonmetals. This type of bond involves the sharing of electrons between atoms. Nitrogen is able to form covalent bonds because it has an outermost electron shell with five valence electrons, and it can share three of these electrons with oxygen to form a stable molecule.
2) Oxygen fluoride (OF2) forms a molecular crystal, which means that individual molecules of OF2 are held together by intermolecular forces. These forces are relatively weak compared to the strong covalent bonds within each OF2 molecule. Therefore, OF2 exists as a gas at room temperature and forms a molecular crystal.
3) The equation for the reaction between oxygen difluoride (OF2) and steam (H2O) to form oxygen (O2) and hydrogen fluoride (HF) is:
OF2 + H2O → O2 + 2HF
