Question

НЕ МОГУТ совместно находится в растворе в значительных количествах:1) S и Н2) SO3 и Na3) K и S 4) Pb и Ch3COOи пояснение, если можно

Answer 1

H и S Так как,соединяясь,они образуют H2S сероводородную кислоту,которая уходит из сферы раствора в виде газа

Answer 2

Substances that Cannot Exist in Significant Amounts Together in Solution

1) Sulfur (S) and Hydrogen (H2): Sulfur and hydrogen cannot exist together in significant amounts in solution. Sulfur is a non-metal and hydrogen is a gas. They have different physical properties and do not readily dissolve in each other. When sulfur and hydrogen are mixed, they form a gas mixture rather than a homogeneous solution.

2) Sulfur Trioxide (SO3) and Sodium (Na): Sulfur trioxide and sodium cannot exist together in significant amounts in solution. Sulfur trioxide is a highly reactive compound that readily reacts with water to form sulfuric acid. Sodium, on the other hand, is an alkali metal that readily dissolves in water to form sodium hydroxide. The reaction between sulfur trioxide and sodium would result in the formation of sodium sulfate and water, rather than a stable solution.

3) Potassium (K) and Sulfur (S): Potassium and sulfur cannot exist together in significant amounts in solution. Potassium is an alkali metal and sulfur is a non-metal. They have different chemical properties and do not readily dissolve in each other. When potassium and sulfur are mixed, they form a mixture rather than a homogeneous solution.

4) Lead (Pb) and Acetate (CH3COO): Lead and acetate cannot exist together in significant amounts in solution. Lead is a heavy metal and acetate is an anion derived from acetic acid. Lead acetate is sparingly soluble in water and forms a precipitate rather than a stable solution. The solubility of lead acetate is limited, and it is often used as a test for the presence of sulfide ions in solution.
