Endothermic
Dissolution is an exothermic reaction.
im guessing here but it is probaly exothermic reaction as there is alot of heat given of
Yes, the reaction of sodium with water is highly exothermic.When sodium is dropped in water, a shiny grobule of sodium is formed which darts around on the surface of water.Hydrogen is liberated in the process which catches fire immediately and burns with a pale blue flame.NaOH is also formed in the process. EQUATION: 2Na+water -> NaOH + H2
Citric acid dissolves in water in an endothermic reaction.
copper gets cleaned with the citric acid do a google search for the science init

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.

Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions. Example: Mixture of sodium and chlorine to yield table salt In other words, combination reactions are exothermic. Reactions that absorb energy or require energy in order to proceed are called endothermic reactions. For example: In the process of photosynthesis, plants use the energy from the sun to convert carbon dioxide and water to glucose and oxygen.
The reaction between baking soda and citric acid is a neutralization and therefore endothermic. It absorbs energy from its environment rather than exerting it.
This makes an endothermic reaction and a drop in temperature. When the baking soda is added to the citric acid it begins to bubble. After a few seconds the citric acid will stop bubbling and remain calm.
Any reaction occur in solid state.

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.
