Question

Пожалуйста:) ZN(OH)2>ZNO>ZNCO3>ZNCL2

Answer 1

-------------------------

Answer 2

The given expression ZN(OH)2 > ZNO > ZNCO3 > ZNCL2 represents the order of reactivity or solubility of different zinc compounds. Let's break down the expression and understand what it means.

Reactivity and Solubility of Zinc Compounds:

Zinc (Zn) is a chemical element that can form various compounds with different elements. The reactivity and solubility of these compounds can vary depending on the specific compound and the conditions.

ZN(OH)2:

ZN(OH)2 refers to zinc hydroxide. It is an inorganic compound that is formed when zinc reacts with water or hydroxide ions. Zinc hydroxide is a white solid that is sparingly soluble in water. It can dissolve in acidic solutions to form zinc salts.

ZNO:

ZNO represents zinc oxide. It is an inorganic compound that is formed when zinc reacts with oxygen. Zinc oxide is a white powder that is insoluble in water. However, it can dissolve in acidic or alkaline solutions to form zinc salts.

ZNCO3:

ZNCO3 refers to zinc carbonate. It is an inorganic compound that is formed when zinc reacts with carbon dioxide and water. Zinc carbonate is a white solid that is sparingly soluble in water. It can dissolve in acidic solutions to form zinc salts.

ZNCL2:

ZNCL2 represents zinc chloride. It is an inorganic compound that is formed when zinc reacts with chlorine. Zinc chloride is a white solid that is highly soluble in water. It can dissolve in water to form a clear, colorless solution.

Order of Reactivity or Solubility:

Based on the given expression ZN(OH)2 > ZNO > ZNCO3 > ZNCL2, it suggests that zinc hydroxide (ZN(OH)2) is the least reactive or least soluble compound among the four. Zinc oxide (ZNO) is more reactive or soluble than zinc hydroxide but less reactive or soluble than zinc carbonate (ZNCO3). Finally, zinc chloride (ZNCL2) is the most reactive or most soluble compound among the four.

Please note that the reactivity and solubility of compounds can be influenced by various factors such as temperature, pressure, and the presence of other substances. The given expression provides a general order but may not hold true in all situations.
