The insoluble salts below are put into 0.10 M hydrochloric acid solution. Do you expect their solubility to be more, less, or ab
White raven [17]

Answer:

Zinc sulfide- more soluble in 0.10 M hydrochloric acid solution

Silver chloride- less soluble in 0.10 M hydrochloric acid solution

Lead iodide- same solubility in 0.10 M hydrochloric acid solution as in pure water

Silver hydroxide- same solubility in 0.10 M hydrochloric acid solution as in pure water

Explanation:

Solubility refers to the amount of a substance that dissolves in 1 dm^3 of solvent. Several factors influence the dissolution of solutes in a given solvent. Some substances dissolves at a low pH (in acid solutions) while other dissolve at a low pH (in basic solutions).

For Silver chloride, its solubility decreases in 0.10 M hydrochloric acid solution because of common ion effect when compared to its solubility in pure water.

a nuclide of 64/29 cu absorbs a positron. witch is the resulting atom? (A) 65/29Cu (B) 63/29 CU (C) 64/28Ni (D) 64/30 Zn
Nesterboy [21]

Answer : Option D) Zn^{64}_{30}

Explanation : When a positron is getting absorbed it means it will be e^{+1}_{0} so, the Cu^{64}_{29} will get converted;

So, the whole reaction will be;

Cu^{64}_{29} + e^{+1}_{0} ----> Zn^{64}_{30}.

This will convert the whole element of Cu will get changed into Zn. As, it absorbs by the positron, the atomic number gets increased from 29 to 30.
