What else can I help you with?
Is h2o plus energy to h2 plus o2 an exothermic reaction?
No. It is endothermic because it absorbs energy.
Is Alka Seltzer in water a endothermic or exothermic reaction?
The dissolution is endothermic.
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.
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.
What is a sentence using the word endothermic?
(An endothermic process is one that absorbs heat.)"An endothermic reaction just took place between the water and the chemical.""Boiling water is an endothermic process that adds energy to the water molecules."
What is a sentence for the term endothermic reaction?
Turning water into hydrogen and oxygen is an endothermic reaction called electrolysis. An endothermic reaction only continues while energy is being added to the reactants.
A reaction that absorbs energy is called?
Endothermic-take in Heat, as opposed to exothermic which gives off heat-like a fire or explosion.
Is water freezing an example of an endothermic reaction?
No, water freezing is not an endothermic reaction; it is an exothermic process. During freezing, water releases heat to its surroundings as it transitions from a liquid to a solid state. This release of energy is what causes the temperature of the surroundings to decrease. In contrast, an endothermic reaction absorbs heat from the environment.
What happens to boiling water if you increase temperature?
evaporation This is the chemical reaction for water heating: H2O (liquid) + heat ---> H20 (gas) This is an endothermic reaction, meaning that by adding heat, it will shift the reaction towards the products, thus making more H2O gas. It is simply a phase change.
Is baking soda and citric acid a endothermic or exothermic reaction?
It is endothermic. The heat of the water in the calorimeter decreases (giving you a -deltaH), which means that the system absorbed heat, making the reaction endothermic.
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.
What causes endothermic reaction with alka seltzer and water?
When Alka-Seltzer tablets are dissolved in water, the reaction is endothermic because it absorbs heat from the surroundings to break the bonds within the tablet and to dissolve the ingredients. As the tablet dissolves, it releases carbon dioxide gas, which also absorbs heat, causing a temperature decrease and making the reaction endothermic.
