I think the correct answer from the choices listed above is option A. The chemical property of a vinegar is that the <span>pH of vinegar is around 2.4. It tells something about the concentration of hydrogen ions in the solution. The other choices given only describe the physical properties of the substance.</span>
According to Arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. Further, acid and base reacts to form salt and water.
Consider following example.
HCl + H2O → Cl- + H3O+
here, HCl has donated a proton, hence it is an acid.
Now consider following reactionHCl + NaOH ↔ NaCl + H2O
in this reaction, HCl donates proton, hence it is acid. On other hand, NaOH donates hydroxyl ion (i.e. OH-), hence it is a base.
Answer:
hydrogen bond are found between nucleotides
Yes they do nonmetals form anions and metals form cations
