NaBr < H3O+1 = OH-1 < Na^+1 = Br^-1 < H2O
<span>Least is NaBr (100% dissolved so no NaBr remains, only Na^+1 and Br^-1 </span>
<span>H2O yields 10^-7 M H3O^+1 and 10^-7 M OH^-1 (Kw = 1x10^-14 = [H3O+][OH-] </span>
<span>Na^+1 and Br^-1 will bothe be 0.1 M </span>
<span>H2O is slightly less that 1000 g / L in a 0.1 M NaBr solution, so its concentration is about 55.5 M</span>
Answer:
I believe the answer is: C a bear living in a hollowed-out log.
Because:
The bear is living and the hollowe-out-log isn't.
Sorry i don’t know the answer i just wanted to inform you that, that persons link is fake.
The shape of NH3 is <span>trigonal pyramidal.</span>
Ionic bonds are easily disrupted in aqueous solutions, as they can ionize readily and as a result be surrounded by the solvent, water, where the partial positive and negative charges would be surrounding the appropriate charge of the ions.
