Question

Ca$^{2+}$(aq) + 2Na(s) --> Ca(s) + 2Na$^{+}$(aq) is a spontaneous reaction. Activity Series: Li(s) --> Li$^{+}$(aq) + e$^{-} K(s) --> K$^{+}$(aq) + e$^{-} Ca(s)--> Ca$^{2+}$(aq) + 2e$^{-} Na(s) --> Na$^{+}$(aq) + e$^{-} True False

          Ca$^{2+}$(aq) + 2Na(s) --> Ca(s) + 2Na$^{+}$(aq) is a spontaneous reaction.
Activity Series:
Li(s) --> Li$^{+}$(aq) + e$^{-}
K(s) --> K$^{+}$(aq) + e$^{-}
Ca(s)--> Ca$^{2+}$(aq) + 2e$^{-}
Na(s) --> Na$^{+}$(aq) + e$^{-}
True
False

Ca^2+(aq) + 2Na(s) –> Ca(s) + 2Na^+(aq) is a spontaneous reaction.
Activity Series:
Li(s) –> Li^+(aq) + e^-
K(s) –> K^+(aq) + e^-
Ca(s)–> Ca^2+(aq) + 2e^-
Na(s) –> Na^+(aq) + e^-
True
False
