Question


What's the formula for chlorine dioxide?

  1. ClO2
  2. CLO
  3. ClO3
  4. HClO

hintHint:

The prefix in the chemical name is the subscript in the formula.

The correct answer is: ClO2


    • The prefix in the chemical name is the subscript in the formula.
    • The prefix of oxygen is -di this means there are two oxygen atoms.
    • The chemical formula is ClO2.

    What is the chemical formula for Tetrasulfur pentoxide?

    An inorganic substance with the formula S4N4 is tetrasulfur tetranitride. The most significant binary sulfur nitride—compounds containing sulfur and nitrogen —is this solid with a golden-poppies hue. Due to its unusual structure and bonding, it is a precursor to many S-N compounds.
    ¶To air, S4N4 is stable. However, it is unstable in the thermodynamic sense with a positive enthalpy of formation of +460 kJ/mol. The difference in energy between S4N4 and its extremely stable breakdown products is what causes this endothermic enthalpy of formation:
    ¶2 S4N4 → 4 N2 + S8
    ¶Metal complexes and S4N4 react. Therefore, in some instances, the cage is still in good condition, but not in others.
