    lithium sulfate: LiSO4 is incorrect.
    Should be
    [tex]Li^{+}_{2} SO_{4}^{2-}[/tex]

    Answer:

    5.Lithium sulfate:[tex]LiSO_4[/tex]

    Explanation:

    We have to find the formula which is incorrect for the name given

    1.Calcium nitrate :[tex]Ca(NO_3)_2[/tex]

    We know that Charge on calcium ion =+2

    Charge on nitrate ion=-1

    Therefore, the formula of calcium nitrate is [tex]Ca(NO_3)_2[/tex].

    Hence, it is true.

    2.Ammonium cyanide:[tex]NH_4CN[/tex]

    Charge on ammonium ion=+1

    Charge on cyanide ion=-1

    Therefore, the formula of ammonium cyanide is [tex]NH_4CN[/tex].

    Hence, it is true.

    3.Strontium carbonate :[tex]SrCO_3[/tex]

    Charge on strontium ion=+2

    Charge on carbonate ion=-2

    Therefore, the formula of strontium carbonate is [tex]SrCO_3[/tex].

    Hence, option is true.

    4.Potassium acetate:[tex]KC_2H_3O_2[/tex]

    Charge on potassium ion=+1

    Charge on acetate ion=-1

    Therefore , the formula of potassium acetate is [tex]KC_2H_3O_2[/tex].

    Hence, option is true.

    5.Lithium sulfate:[tex]LiSO_4[/tex]

    Charge on lithium ion=+1

    Charge on sulfate ion=-2

    Therefore, the formula of lithium sulfate is [tex]Li_2SO_4[/tex].

    But given formula is [tex]LiSO_4[/tex].

    Hence, option is false.
