Answer: Основна функція сну — це відновлення фізичних та психічних сил, яке дозволяє максимально адаптуватися до зміни умов зовнішнього і внутрішнього середовищ. Сон становить собою чергування різних функціональних станів головного мозку, а не є «відпочинком» для головного мозку, як вважали раніше.

List 3 factors that can speed up the rate of chemical reactions

zysi [14]

Answer:

Temperature
Greater Surface Area
Catalysts

Explanation:

Temperature

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Greater Surface Area

The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. ... more particles are exposed to the other reactant. there are more collisions. the rate of reaction increases.

Catalysts

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.
