N2O3 dinitrogen trioxide
N2O4 dinitrogen tetroxide
N2O5 dinitrogen pentoxide
Answer is: <span>reversible reaction.
</span>The concentrations<span> of reactants and products in an equilibrium mixture are determined by </span><span>the </span>equilibrium constant K<span>.
</span>When writing chemical equations for reversible reactions, two arrows are used, for example: NH₄Cl(s) ⇆ NH₃(g) + HCl(g) or
CuSO₄(s) + 5H₂O(l) ⇆ CuSO₄·5H₂<span>O(s).</span>

Answer:
ions with opposite charge
Explanation:
ionic bond is formed between oppositely charged ions in a chemical compound.
<span>There's a trend in electronegativity. The bottom left of periodic table is the lowest (0.7) and the upper right is the highest (4.0). The most polar is the greatest difference in electronegavity.
hbr- 1~ , hi- 0.5~ ,hcl - 1.3~ , hf-1.8 so,hf is the answer</span>
