WebLight sticks come in a variety of colors. The color of the light is determined by the chemical make-up of the fluorescent dye in the stick. We saw that light sticks use energy from a chemical reaction to emit light. This … WebThe kinetic energy of the spring is equal to its elastic potential energy, i.e. 1/2mv^2 = 1/2kx^2 when the spring is stretched some distance x from the equilibrium point and when its mass also has some velocity, v, with which it is moving. This occurs somewhere in between the equilibrium point and the extreme point (extreme point is when x ...

WebApr 12, 2024 · They tell you that voltage bumps and irregularities can increase an unnecessary energy to be consumed, and that these devices stabilize the voltage and regulate the current at home, which leads to less consumption, and up to 20%-50% saving on the bill! That’s a complete lie. WebSep 1, 2024 · The heat ignites the phosphorus that has reached the match head of the match when rubbing. Redoxreaction (example): 3/4 S 8 + 4 KClO 3 –→ 6 SO 2 + 4 KCl This triggers the reaction between sulfur or antimony sulfide and oxygen. The oxygen is supplied by the oxidizing agent potassium chlorate. WebJun 2, 2024 · Glow Sticks and the Rate of Chemical Reaction. A glow stick is an example of chemiluminescence. This means luminescence or light is produced as the result of a chemical reaction. Several factors affect the rate of a chemical reaction, including temperature, concentration of reactants, and the presence of other chemicals. irmhild poulsen
