How does the temperature of water effect how fast the chemical reaction of Alka-Seltzer happens?
I think the Alka-Seltzer will react faster in very hot water because the molecules are moving around faster. Therefore, they will run into each other faster causing a faster chemical reaction.
Molecules: Two or more atoms which have chemically combined to form something
Temperature: A measure of warmth or coldness
Reaction Rate: The speed of a reaction
Reactants: The substance(s) first involved in a chemical reaction
Chemical reaction: The process of one or more substances changing into another
Chemical bond: sharing or transfer of electrons between participating atoms
Chemical reactions are studied in chemistry. Chemical reactions usually involve moving electrons in the forming and breaking of chemical bonds. A chemical change has to happen, that is when one substance changes into another. An example of a chemical change is a bike that is rusting because the metal changes into something different (rust). In my experiment, Alka-Seltzer and water mix together and cause a chemical reaction. Alka-Seltzer is made of aspirin, citric acid, and sodium bicarbonate (NaHCO3).
Na-sodium, H-hydrogen, C-carbon, O-oxygen
When mixed with water it makes bubbles of carbon dioxide gas.
Molecules in a solution (a mixture of 2 or more substances) are in constant motion and are constantly colliding with each other. In order for a chemical reaction to occur the molecules have to hit each other. The temperature of a solution measures the motion of the molecules in the solution. The higher the temperature, the faster the molecules move around. The lower the temperature the slower the molecules move around.
