Copper oxide and zinc reaction
Bildnummer 11520196
| Copper oxide and zinc,undergoing an exothermic displacement reaction. The reaction is self- perpetuating after being initially lit,since it provides its own heat energy needed for the reaction to continue. Reactions that give off heat are known as exothermic. A displacement reaction is when an element is displaced from its compound (copper oxide,CuO) by a more reactive element (zinc,Zn),to produce the element in its pure form (copper metal,Cu) and a new compound (zinc oxide,ZnO). The zinc oxide is seen as a yellow powder (centre,left) which turns white when cool | |
