Which of the following is not true for an exothermic reaction?

Gennadij [26K]

Answer:

The false statement regarding an exothermic reaction is: A. the products have a higher enthalpy than reactants

Explanation:

An exothermic reaction is a type of chemical reaction that involves the release of energy from the system to the surroundings. Thus increasing the temperature of the surroundings.

In this reaction, the enthalpy or energy of the reactants is greater than the enthalpy or energy of the products. ( $\Delta H_{f} (Products) < \Delta H_{f} (reactants)$ )

As the enthalpy change of a reaction: $\Delta H_{r} = \sum \Delta H_{f} (Products) - \sum \Delta H_{f} (reactants)$

Therefore, the enthalpy change for an exothermic reaction is negative ( $\Delta H_{r} < 0$ )

What happens to lipids when they are placed in water?

mestny [16]

Lipids are much denser than water so they often " float " on water and also because that lipids and water can not dissolve to form a solution. lipids always tend to remain at top of water since they are denser .
