Explanation:
Given the choices;
A) A candle flame
B) Baking bread
C) The chemical reaction in a "cold pack" often used to treat injuries
D) The vaporization of water
The correct answer would be A, a candle flame.
An exothermic reaction is a type of reaction where energy is lost from the system to the surroundings in form of heat and light energy. The opposite of exothermic reaction is the endothermic reaction where energy is absorbed from the surrounding to the system.
E = energy in the light rays = h ν = h c /λ = 6.67 * 10×⁻³⁴ * 3 * 10⁸ / (5.84*10⁻⁸) J = 3.42 * 10⁻18 JKinetic energy of electrons = 1/2 m u^2 = 1/2 * 9.1 * 10⁻³¹ * (2.45 * 10⁶)² J = 2.73 * 10⁻¹⁸ J The ionization energy = (3.42 - 2.73) * 10⁻¹⁸ J = 6.9 * 10⁻¹⁹ J
