(d) why does the h3o concentration have more influence on the precipitation of the salt of a weak acid, such as cac2o4(s), than on the precipitation of the salt of a strong acid, such as agcl(s) or caso4(s)?

See explanation

Explanation:

When we are comparing the effect of H3O^+ on the precipitation of a salt of a weak acid such as CaC2O4(s) and that of a strong acid such as AgCl(s) or CaSO4(s), we discover that H3O^+ has more effect on the precipitation of the salt of a weak acid.

This is because, anions of the weak acid combine with H^+ from H3O^+ thereby decreasing the concentration of the anion of the salt of the weak acid and increasing the solubility of the precipitate.

answer; /// i do believe that the correct answer is (c)nuclear bond

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
