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.

using avogadro’s law
The first thing you need to do is convert mL into L
so (175 mL)(.001L/1mL)=.175L then you multiply by the Molarity of H3PO4 which is 3.5mol/L so (.175L)(3.5mol/L)=.6125 mol H3PO4, and since it wants the answer in grams you then multiply (.6125molH3PO4) by the molar mass of H3P04 which is about 97.99g and your answer is 60.02g which is about 60 grams of H3PO4. Hope this helped
Answer:
The answer to your question is below
Explanation:
A qualitative property of matter is a property characteristic of a substance like color and flavor.
A quantitative property of matter is a property when we get a number.
A) it's a circular shape is a qualitative property because the shape is a qualitative property and shape is not represented by a number.
B) its mass is 1.5 kg is a quantitative property because we know a number of this mass.
C) it tastes like chocolate is a qualitative property because the flavor is characteristic of a substance and flavor is not measured in numbers.
D) it is 30 cm in diameter it is a quantitative property, we know the exact dimension of it.
E) its icing is melting is a qualitative property, melting is a property of ice, it just happens.
