Answer 1

Answer:

ANSWER IS NO3

Explanation:

BECAUSE U KNOW IT

Answer 2

The statement that is incorrect is "the O–O bond length in H2O2 is slightly smaller than that in O2^2-" (option 2).

• The O-O bond length in H2O2 is actually slightly longer than that in O2^2- rather than slightly smaller. This is because the two oxygen atoms in H2O2 are both bonded to a central hydrogen atom, which introduces steric repulsion and weakens the O-O bond.
• In contrast, the two oxygen atoms in O2^2- are bonded to two highly electronegative atoms, which strengthens the O-O bond.
• Statement 1 is true as the electronegativity of fluorine is greater than oxygen, leading to a shorter O-O bond length in O2F2 than in H2O2.
• Statement 3 is also true as both O2^2- and O2^2+ have two unpaired electrons, making them paramagnetic.
• In summary, the correct answer is 2) The O–O bond length in H2O2 is slightly smaller than that in O2^2-.
