Once you have chosen your two everyday chemical reactions, conduct research to determine the
chemical equations that are used to represent those reactions. list the two reactions and their
chemical equations in your post. also, state the type of each reaction, such as synthesis,
decomposition, combustion, or one of the displacement reactions. then, explain why each reaction
falls into that specific category.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).
