Write word equation for the following molecular equation:
CaO + H20 → Ca (OH)2 + Δ
State why [+ Δ ] is not written in the reaction, if ZnO reacts with H2O.
Calcium oxide + Water→Calcium hydroxide + heat
When ZnO reacts with H20, the equation formed is
ZnO + H20 →Zn(OH)2
+ Δ is not written in the reaction because in this case heat is released not evolved.
