Answer: The molecular formula of ammonia is NH3.
Step-by-step explanation:
Ammonia and calcium carbonate are two separate compounds, each with their own molecular formulas.
The molecular formula of ammonia is NH3. It consists of one nitrogen (N) atom bonded to three hydrogen (H) atoms.
The molecular formula of calcium carbonate is CaCO3. It consists of one calcium (Ca) atom bonded to one carbonate ion (CO3), which in turn consists of one carbon (C) atom bonded to three oxygen (O) atoms.
Therefore, there is no single molecular formula for "ammonia calcium carbonate" as it refers to a combination of two distinct compounds.
