    Answer:

    Here’s your answer BUDDY…

    Explanation:

    a.) When zinc is added to copper sulphate (CUSO4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.

    The chemical equation of the reaction,

    Zn + CuSO4 → ZnSO4 + Cu

    b.) 3 HCl + Fe(OH)3 → FeCl3 + 3 H2O

    When dilute Hydrochloric acid is added to iron filings, iron chloride & hydrogen gas is produced.

    Fe+2HCl⟶FeCl

    2

    +H

    2

    The iron displaces hydrogen from hydrochloric acid to form iron (II) chloride & hydrogen gas. This is a single displacement reaction.

    c.) sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas. Zn(s)+2NaOH(aq)+2H2O(l)→Na2Zn(OH)4(aq)+H2(g)
