## Answers ( 2 )

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

2. 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.
