Na2SO4 is an ionic compound because it is composed of a metal (Na) and a nonmetal (S and O). Ionic compounds form when metal atoms transfer electrons to nonmetal atoms, resulting in the formation of positively and negatively charged ions that are held together by electrostatic forces.
Molecular equation: CuSO4 + Na2CO3 → CuCO3 + Na2SO4 Net ionic equation: Cu2+ + CO3^2- → CuCO3
Zinc (Zn) is an elemental metal and is not considered molecular or ionic. It exists as individual atoms in its solid metallic form.
This is sodium sulfate, or more properly sodium sulfate(VI).
Mg is an ionic element. It typically forms cations with a 2+ charge by losing two electrons to achieve a stable electronic configuration.
Neither, because silicon is an element, not a compound.
Na2SO4 is not a molecular formula because it represents an ionic compound, sodium sulfate. In ionic compounds, the elements are held together by ionic bonds rather than sharing electrons in covalent bonds like in molecular compounds. The formula Na2SO4 indicates that there are two sodium ions (Na+) for every sulfate ion (SO4^2-).

Sodium sulfate is an ionic compound, consisting of Na+ and SO4^2- ions, held together by ionic bonds. It does not exist as individual molecules like covalent compounds do, so it does not have a molecular formula.
This is sodium sulfate, or more properly sodium sulfate(VI).
Mg is an ionic element. It typically forms cations with a 2+ charge by losing two electrons to achieve a stable electronic configuration.
Neither, because silicon is an element, not a compound.
