The Alka-Seltzer tablet contains citric acid and sodium bicarbonate (baking soda). When put in water, those two 'chemicals' react. The warmer the water, the faster the reaction.

Is Alka Seltzer in water a endothermic or exothermic reaction?
The dissolution is endothermic.
Is the reaction of Alka-Seltzer and water endothermic or exothermic?
exothermic
Is the reaction of borax and water endothermic or exothermic?
Exothermic reaction
What evidence of a chemical reaction might you see by dropping an alka seltzer in water?
its a chemical reaction becase once the alka seltzer melts you cant take it out and put it back together
What causes an exothermic reaction with alka seltzer?
Alka-Seltzer contains aspirin, sodium bicarbonate (baking soda) and citric acid. When placed in water, the tablet dissolves. The citric acid reacts with the baking soda, and gives off carbon dioxide, which makes bubbles in the water. If you have heartburn, that is caused by too much stomach acid. The baking soda in an Alka-Seltzer counteracts the stomach acid.
Is Alka Seltzer in water a endothermic or exothermic reaction?
The dissolution is endothermic.
Is the reaction of Alka-Seltzer and water endothermic or exothermic?
exothermic
Is water gas reaction endothermic?
yes it is a endothermic reaction
When sodium hydroxide is added to water the reaction is endothermic or exothermic?
Endothermic
Is the dissolving of sodium thiosulfate in water endothermic or exothermic reaction?
H2O + Na2SO4 = Exothermic reaction
Does the temperature have any effect on the reaction of water with alka-seltzer?
Ultimately, the temperature has little effect of the reaction of water and Alka-Seltzer. However, warmer water will make the reaction occur and finish a bit faster.
Is the reaction of borax and water endothermic or exothermic?
Exothermic reaction
Is the dissolving of sodium chloride in water endothermic or exothermic reaction?
It is small, but overall endothermic.
Is the reaction between caesium and water exothermic or endothermic?
This is a strong exothermic reaction.
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.
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."
Is salt dissolving in water an example of an endothermic reaction yes or no?
no
