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.
