Is an exergonic reaction always exothermic, or are there exceptions where the two terms do not align?
An exergonic reaction is not always exothermic. While exergonic reactions release energy, they can be either exothermic (release heat) or endothermic (absorb heat). The terms exergonic and exothermic do not always align because exergonic refers to the overall energy change in a reaction, while exothermic specifically refers to the release of heat.
What happened when the lye dissolve in the water in terms of energy?
When lye dissolves in water, it releases energy in the form of heat. This process is exothermic, meaning that energy is released as the lye particles interact with the water molecules, forming a strong, alkaline solution.
What is the difference between an exothermic and exergonic reaction in terms of energy release and spontaneity?
An exothermic reaction releases energy in the form of heat, while an exergonic reaction releases energy in the form of free energy. Both reactions are spontaneous, meaning they occur without needing an external energy source.
What does chemical work mean?
Chemical work refers to the energy associated with a chemical reaction or transformation. It involves the breaking and forming of chemical bonds, and is often measured in terms of the change in the internal energy of a system during a reaction. This energy can be used to do work or drive other processes.
Which pair of terms best describes the type of change that occurred in the reaction hydrogen plus oxygen leads to water plus energy?
Chemical change and exothermic. In this reaction, hydrogen and oxygen undergo a chemical change to form water, releasing energy in the form of heat and light.
Contrast the forming and breaking of chemical bonds in terms of energy changes?
The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.

What is the difference between endothemic and exothemic?
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
What is the appropriate definition for chemical reaction in terms of science?
A chemical reaction is a process that results in the transformation of one set of chemical substances into another. It involves the breaking and forming of chemical bonds, leading to the creation of new substances with different properties.
Is a liquid endothermic or exothemic?
A liquid on its own cannot be described as either endothermic or exothermic. The terms endothermic and exothermic are the names of two opposite process reactions. An endothermic reaction absorbs heat and and exothermic reaction gives off heat. A liquid can be involved in either an endothermic reaction or in an exothermic reaction. If you are evaporating a liquid from its liquid phase to its gas phase, then the reaction is usually endothermic and vice versa, going from the gas phase to the liquid phase, the reaction is usually exothermic.
Is the dissolution of calcium hydroxide exothermic or endothermic?
Exothermic: Heat is given off as one of the products. The container holding the reactants and the products gets hot during the reaction. Use approximately 5 mL of 6M HCl and add to a testtube containing a small peice of mossy Zn. Immediately place a thermometer in the testtube and you will see a quick rise in temperature. This rise in temperature indicates that heat is given off which is a clear sign of an exothermic reaction. Hope this helps!!

An exothermic reaction releases energy in the form of heat, while an exergonic reaction releases energy in the form of free energy. Both reactions are spontaneous, meaning they occur without needing an external energy source.
Is water vapor condensing on a glass exothermic or endothermic?
Steam itself is not endothermic or exothermic - only chemical reactions can be labelled as exothermic or endothermic the reaction whithin the steam can only be exothermic or endothermic
What are four scientific word for elephant toothpaste?
Elephant toothpaste is a popular demonstration that involves the rapid decomposition of hydrogen peroxide. Four scientific terms related to this reaction include: catalyst (often potassium iodide or yeast), exothermic reaction (as heat is released), decomposition reaction (breaking down hydrogen peroxide), and foaming agent (the soap used to create bubbles).
What does chemical work mean?
Chemical work refers to the energy associated with a chemical reaction or transformation. It involves the breaking and forming of chemical bonds, and is often measured in terms of the change in the internal energy of a system during a reaction. This energy can be used to do work or drive other processes.
What does exothermic mean in terms of thermodynamics?
Exothermic means that heat energy is given off from the reaction. In turn this means that the enthalpy (stored chemical energy) decreases. Best example of an exothermic reaction is combustion reactions (reacting with oxygen, or even more simply: burning). The opposite of exothermic is endothermic.
