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 evaporating always an exothermic reaction?
No, evaporating is not always an exothermic reaction. Evaporation is the process of a liquid turning into a gas, and whether it is exothermic or endothermic depends on the specific conditions such as temperature and pressure.
Is baking soda and vinegar an endothermic or exothermic reaction?
This is a chemical change because once the substances are put together to form a gas it cannot be changed.
If rubidium is added to water will it be endothermic or exothermic?
The reaction between rubidium and water is highly exothermic, leading to the spontaneous production of hydrogen gas and the formation of rubidium hydroxide. This exothermic reaction is typically very vigorous and can even result in the ignition of the hydrogen gas produced.
Is burning gasoline an exothermic process or an endothermic process?
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Is citric acid and sodium hydrogen carbonate endothermic or exothermic?
The reaction between citric acid and sodium hydrogen carbonate is typically exothermic, meaning it releases heat. This is why it's commonly used in bath bombs to create a fizzing reaction and release carbon dioxide gas.
Is ammonia solution and water an exothermic or endothermic reaction?
Gas devolve reactions are exothermic. So it is a exothermic too.
Is reaction between hydrochloric acid and aluminum endothermic or exothermic?
The reaction between hydrochloric acid and aluminum is exothermic because it releases heat as the products are formed. This reaction produces hydrogen gas and aluminum chloride.
What is a chemical reaction that absorbs heat?
An example of a chemical reaction that absorbs heat is the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) to produce carbon dioxide gas. This reaction is endothermic, meaning it absorbs heat from its surroundings, causing the mixture to feel cold to the touch.
When oil is burned is it endothermic?
Fire creates an exothermic reaction, not endothermic. To be endothermic, the reaction must draw in heat from its surroundings, thereby making things colder.
Is the reaction between caesium and water exothermic or endothermic?
The reaction between caesium and water is exothermic, meaning it releases heat. This is because when caesium reacts with water, it forms caesium hydroxide and hydrogen gas, releasing energy in the process.
When Natural gas is burned in a furnace is it endothermic or exothermic?
When natural gas is burned in a furnace, it undergoes an exothermic reaction, which means it releases heat. The combustion of natural gas produces carbon dioxide, water vapor, and heat energy as byproducts.
