Question
a) In the double displacement reaction between chromium (III) nitrate and ammonium carbonate, the molecular formula of chromium (III) nitrate is____ , the molecular formula of ammonium carbonate is_____ , the molecular formula of the product containing chromium (III) ion is_____ , and the molecular formula of the product containing ammonium ion is_____ .
b)In the double displacement reaction between mercury (II) acetate and lithium phosphate, the molecular formula for mercury (II) acetate is____ , the molecular formula for lithium phosphate is_____ , the molecular formula of the product containing mercury (II) ion is_____ , and the molecular formula of the product containing lithium ion is_____ .
(hint: remember, the molecular formula for acetate in this class is C2H3O2-, and your answers are case sensitive)
Explanation / Answer
2Cr(NO3)3 +3 (NH4)2CO3 ------> 6NH4NO3 + Cr2(CO3)3
