Explanation:
substitution reaction (also known as single displacement reaction or single substitution reaction) in a chemical reaction during which one functional group in chemical compound is replaced by an other functional group. a good example of a substitution reaction is halogenation .
ZnO + 2HNO₃→ Zn(NO₃)₂ + H₂O
mol Zn(NO₃)₂ = mol ZnO = 0.2 (from the coefficient)
mass Zn(NO₃)₂ = 0.2 x 189 = 37.8 g (theorethical yield)
% yield = 15.3 : 37.8 x 100% = 40.48%

Explanation:
Answer:
C2H6 + 2 Cl2 = C2H4Cl2 + 2 HCl
Explanation:
When a metal reacts with an acid, say HCl, it reacts with the H+ atoms of the acid to produce H2 gas and chloride ions. Since pH is the negative log of H+ concentration, then it would sensibly decrease because it was used up. The metal oxide would form a coating over the metal. However, as the reaction proceeds, the acid corrodes the metal and exposes a purer surface removing the coating. Thus increasing the concentration of H+.
