Question

Which set of chemical name and chemical formula for the same compound is correct?

a. iron (III) phosphate, FePO₄
b. ammonium sulfite, (NH₄)2S
c. magnesium dichromate , MgCrO₄
d. lithium carbonate, LiCO₄

Answer 1

The correct set of chemical name and formula is d. lithium carbonate, Li2CO3. Other options have incorrect formulas for the given names.

Step-by-step explanation:

The correct set of chemical name and chemical formula for the same compound is d. lithium carbonate, Li2CO3. Option a is incorrect because iron (III) phosphate should be FePO4. Option b is incorrect because ammonium sulfite is actually (NH4)2SO3. Option c is incorrect because magnesium dichromate should be MgCr2O7. Therefore, option d provides the correct name and chemical formula.
