Ca(HCO3)2 is the correct formula for this compound.

Certainly! Let's break down the chemical formulas you provided and write them in names.

1. CaHCO3:
To determine the name of this compound, we need to identify each element and its corresponding charge.
- "Ca" stands for calcium, which has a charge of +2.
- "HCO3" refers to the polyatomic ion called bicarbonate. It consists of one hydrogen atom (H), one carbon atom (C), and three oxygen atoms (O). The overall charge of bicarbonate is -1.

So, combining these elements and charges, the name of the compound CaHCO3 is calcium bicarbonate.

2. H2SO4:
Breaking this down, we have:
- "H" represents hydrogen.
- "SO4" is the sulfate ion, consisting of one sulfur atom (S) and four oxygen atoms (O). The overall charge of sulfate is -2.

Combining these elements and charges, the name of the compound H2SO4 is sulfuric acid.

3. CaCl2:
Analyzing this formula, we can see:
- "Ca" stands for calcium.
- "Cl" represents chlorine.

Putting these elements together, the name of the compound CaCl2 is calcium chloride.

Remember, when identifying the names of compounds, it is essential to know the elements and their charges as well as the rules of nomenclature.
