DCPIP is a redox dye that starts off blue but will turn reddish-pink in acidic solution.
This chemical is often used in general chemistry experiments with vitamin C (ascorbic acid), which is a good reducing agent. The DCPIP become colorless when it is reduced (remember, it's blue when oxidized).

Answer:Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)
O2Zn(s) + H2SO4(aq) → 22nH(aq) + SO4(s)
Explanation:
Balanced chemical reaction: 2CH₄(g) ⇄ C₂H₂(g) + 3H₂(g).
1) In a chemical reaction, chemical equilibrium is the state in which both reactants (methane CH₄) and products (ethyne C₂H₂ and hydrogen H₂) are present in concentrations which have no further tendency to change with time.
2) At equilibrium, both the forward and reverse reactions are still occurring.
3) Reaction rates of the forward and backward reactions are equal and there are no changes in the concentrations of the reactants and products.
