Use the chemical reaction to answer the question we have CACO small three on the bottom arrow goes to see O2 small two on the bottom plus CA with a big zero scientist heats 30 g of calcium carbonate in the chemical reaction shown, what is the total mass of the products would it be 10 g 30 g 15 g or 60 gI’m

The reaction you provided is the thermal decomposition of calcium carbonate (CaCO₃), which can be represented as:

\[ \text{CaCO}_3 (s) \rightarrow \text{CaO} (s) + \text{CO}_2 (g) \]

In this reaction, calcium carbonate decomposes into calcium oxide (CaO) and carbon dioxide (CO₂).

If you start with 30 g of calcium carbonate, according to the law of conservation of mass, the total mass of the products should equal the mass of the reactants, assuming all of the CO₂ produced is released as a gas and not collected.

So, the total mass of the products will still be:

**30 g.**

Therefore, the correct answer from your options is **30 g**.
