Write down the reaction equations of interaction: a) zinc with sulfuric acid solution; b) calcium with water; c) hydrogen with chlorine; d) hydrogen with copper (II) oxide.
Equations of the above chemical reactions:
a) zinc with sulfuric acid solution:
Zn + H2SO4 = ZnSO4 + H2 ↑;
b) calcium with water:
Ca + 2H2O = Ca (OH) 2 + H2 ↑;
c) hydrogen with chlorine:
H2 + Cl2 (hv) = 2HCl;
d) hydrogen with copper (II) oxide:
CuO + H2 (t) = Cu + H2O.
