So im doing an experiment, putting tums in vinegar, and when i did, the tum fizzed up and bubbled and disentegrated. Would this be endothermic or exothermic. Endothermic right?

Mrs Sue please?

Thanks!

You're welcome.

Yes, you are correct. The reaction between Tums (which contains calcium carbonate) and vinegar (which contains acetic acid) is an example of an endothermic reaction.

To understand why this reaction is endothermic, we need to consider the energy changes involved. When you mix Tums with vinegar, a chemical reaction takes place. The acetic acid in vinegar reacts with the calcium carbonate in Tums, producing carbon dioxide gas, water, and a dissolved form of calcium acetate.

During this reaction, energy is absorbed from the surroundings, resulting in the reaction feeling colder. This is because the breaking of chemical bonds in the Tums and vinegar requires energy input. So the dissolution of Tums in vinegar is an example of an endothermic process.

To confirm your observation, you can perform a simple experiment. Take two containers, one with Tums and vinegar and the other with just vinegar. Measure and record the initial temperature of both containers. Then observe and compare the temperature change over time. You will notice that the container with Tums and vinegar becomes cooler, indicating an endothermic reaction.
