Question
What is the formula for calcium carbonate?
Group of answer choices
- CaCO3
- CaSO4
- CaCO3·6(H2O)
- CaMg(CO3)2
Solution
Breakdown of the Problem
- Identify the chemical compounds provided in the answer choices.
- Determine which option correctly represents calcium carbonate.
Relevant Concepts
- Calcium carbonate is an inorganic compound that is commonly represented in chemistry by its molecular formula.
Analysis and Detail
- CaCO3: This is the molecular formula for calcium carbonate.
- CaSO4: This is the formula for calcium sulfate, which is not calcium carbonate.
- CaCO3·6(H2O): This indicates calcium carbonate with six water molecules attached, representing a hydrated form, but isn't the standard formula for calcium carbonate itself.
- CaMg(CO3)2: This represents dolomite, which contains magnesium in addition to calcium carbonate.
Verify and Summarize
Based on the analysis, the correct formula that directly represents calcium carbonate is CaCO3.
Final Answer
The formula for calcium carbonate is CaCO3.
