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.
Does heating calcium carbonate produce an endothermic or exothermic reaction?
Heating calcium carbonate (CaCO3) produces an endothermic reaction because energy is absorbed in the form of heat to break the bonds between the calcium, carbon, and oxygen atoms in the compound. This results in the decomposition of calcium carbonate into calcium oxide (CaO) and carbon dioxide (CO2).
Is burning ethanol endothermic?
No, burning ethanol is an exothermic reaction because it releases heat energy as it combines with oxygen to form carbon dioxide and water vapor.
What process indirectly removes carbon from the earth's atmosphere?
Photosynthesis is the process that indirectly removes carbon from the Earth's atmosphere. During photosynthesis, plants absorb carbon dioxide from the air and use it to produce glucose and oxygen. This process helps in reducing the amount of carbon in the atmosphere and storing it in the form of plant material.
Which compound is formed from its elements by an exothermic reaction at 298 K and 101.3 kPa?
Carbon dioxide (CO2) is formed from its elements (carbon and oxygen) by an exothermic reaction at 298 K and 101.3 kPa.
Is production of sugar in photosynthesis exothermic and endothermic?
yes it is because you absorb carbon dioxide and water to produce sugar in photosynthesis.
Is carbon dioxide formation endothermic and exothermic?
Exothermic because the heat of formation is -566. Exo- is negative and Endo- is positive.
Is a candle a endothermic or exothermic change?
exothermic- because exothermic gives off heat and endothermic is cold
Is burning alcohol endothermic or exothermic?
When something burns it gives off heat. Therefore, it is exothermic.
Is burning octane exothermic or endothermic?
Burning octane is an exothermic reaction because it releases energy in the form of heat and light as it reacts with oxygen to form carbon dioxide and water.
Is the combustion of propane endothermic or exothernic?
In the presence of excess oxygen, propane burns to form water and carbon dioxide. When not enough oxygen is present for complete combustion, incomplete combustion occurs when propane burns and forms water, carbon monoxide, and carbon dioxide.
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 photosynthesis an exothermic or endothermic reaction?
Yes photosynthesis is a endergonic process i.e. energy-requiring process.
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 dry ice exothermic?
Dry ice sublimation (changing from solid to gas) is an endothermic process because it requires heat energy to break the intermolecular forces holding the solid together. However, when dry ice sublimates in an enclosed space, it can release cold temperatures and feel cold to the touch, but this is due to the removal of heat energy from the surrounding environment, not due to an exothermic reaction.
The synthesis of carbon disulfide is spontaneous and exothermic at room temperature what must be true regarding this reaction?
The reverse reaction is endothermic and nonspontaneous.
Which of the following is true about photosynthesis A. It is an exothermic reaction B. It is an endothermic reaction C. It produces carbon dioxide D. It occurs in animals?
Photosynthesis is an endothermic process.
