    Answer:

    Among the given reactions,

    a. Ag+FeCl 3

    b, Zn + CaO

    C. Ba+Na 2 CO 3

    d . Cr+KNO3

    which reaction is likely to take place based on the reactivity series?

    Explanation:

    The metal reactivity series is:

    Li > K> Ba >Ca>Na > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt

    The highly reactive metal will displace the less reactive metal from its compound during a displacement reaction.

    a. Ag+FeCl 3

    Ag is less reactive than Fe, so Ag cannot displace Fe from its compound.

    This reaction also does not occur.

    b, Zn + CaO

    Zn is less reactive than Ca, so it cannot displace Ca from its compound.

    This reaction does not occur.

    C. Ba+Na 2 CO 3

    Ba is more reactive than Na, so Ba displaces Na from its compound.

    This reaction is possible.

    d . Cr+KNO3

    Cr is less reactive than K, so it cannot displace K from its compound.

    Hence, This reaction is not possible.

    Answer:

    option c) Ba+Na 2 CO 3 -> BaCO3 +2Na
