Cobalt (II) sulfate.
Cobalt tetraoxosulphate (vi) ion
This most likely refers to CoSO4, or cobalt II sulfate, which contains 3 elements: cobalt, sulfur, and oxygen. However, capitalization is important in writing chemical formulas, and the lack of capitalization creates some ambiguity. COSO4, would also contain 3 elements: carbon, sulfur, and oxygen, though this particular configuration is unlikely.
CoO + H2SO4 --> CoSO4 + H2O
Al(SO4)3 ^That is completely wrong. Al(SO4)3 is aluminum sulfate cobalt ii sulfide is CoS actually you both are wronq. its really CoSO4 <<< cobalt sulfate Wow. He/She was right. Your totally wrong. Cobalt (II) Co^2+ and Sulfide is S^2- So the answer is CoS. Signs cancel themselves out..
This solution should contain 0.500 grams anhydrous cobalt(II)-sulfate (CoSO4) per litre.When using mono- or heptahydrate, increase the weighted mass by the relevant molar mass ratio.Molar masses:154.996 g/mol CoSO4 (anhydrous)173.01 g/mol CoSO4.H2O (monohydrate) ==> ratio 173/155 = 1.12, so 0.556 g/L281.103 g/mol CoSO4.7H2O (heptahydrate) ==> ratio 281/155 = 1.81, so 0.905 g/L
AgNO3 + CoSO4 --> Co(NO3)2 + Ag2 SO4 Double displacement reaction This is not balanced quick fix is 2AgNO3 + CoSO4 = Co(NO3)2 + Ag2SO4
Since selenium is a metalloid, and nitrogen is a nonmetal, the normal convention would require us to put nitrogen at the end, not the beginning. Se4N4 is a highly explosive compound called selenium nitride. Other forms of selenium nitride also exist, with different ratios of selenium to nitrogen.
