Question

Помогите пожалуйста в химии.... У меня проект с химией, но пока её у меня нет в школе.А в интернете непонятно.... Так вот, сравните лёд и ацетат натрия(горячий лед). Пожалуйста, я вас умоляю

Answer 1

Лед-это та же самая вода, но, во-первых, с другой кристаллической решеткой, а, во-вторых, в другом агрегатном состоянии.Относится к неорганике.

CH3COONa- органическая натриевая соль уксусной кислоты. Получается она взаимодействием обычного уксуса(уксусной к-ты) и натрия. При переходе в кристаллическое состояние выделяет большое кол-во тепла, за что и названа "горячим льдом"

Answer 2

Comparing Ice and Sodium Acetate (Hot Ice)

When comparing ice and sodium acetate (hot ice), there are several key differences to consider:

1. Physical State: - Ice: Ice is the solid state of water at or below 0°C. It is a transparent, crystalline solid. - Sodium Acetate (Hot Ice): Sodium acetate, when in its supercooled state, is a clear liquid. However, when it crystallizes, it forms a solid mass that resembles ice.

Source: 2. Freezing Point: - Ice: The freezing point of water, and therefore ice, is 0°C. - Sodium Acetate (Hot Ice): The supercooled liquid state of sodium acetate can exist below its normal freezing point, and it solidifies into a crystalline form when triggered.

Source: 3. Heat Absorption/Release: - Ice: When ice melts, it absorbs heat from its surroundings. When it freezes, it releases heat to its surroundings. - Sodium Acetate (Hot Ice): The process of crystallization in sodium acetate is exothermic, meaning it releases heat to its surroundings.

Source: 4. Reusability: - Ice: Ice can be melted and refrozen multiple times without any significant change in its properties. - Sodium Acetate (Hot Ice): Sodium acetate can be melted and solidified repeatedly, making it reusable.

Source: In summary, while both ice and sodium acetate (hot ice) are solid substances at certain temperatures, they have distinct properties related to their freezing points, heat absorption/release, and reusability. Sodium acetate's ability to exist in a supercooled liquid state and its exothermic crystallization process differentiate it from regular ice.
