Sulfurous acid, H2SO3, breaks down into water (H2O) and sulfur dioxide (SO2).If only one molecule of sulfurous acid was involved in a chemical reaction, how many sulfur (S) atoms would be in the products?

Use the chemical equation to find the answers. BaSO4 + H2SO4 → Ba(HSO4)2 Identify how many oxygen atoms are in the product. Identify how many oxygen atoms are in the reactant.

Calcium carbonate can break down to form calcium oxide and carbon dioxide.CaCO3 → CaO + CO2The oxygen atoms on the product side are

When sugar is burned, water vapor and carbon dioxide are produced. A sugar molecule has a specific number of carbon, hydrogen, and oxygen atoms. Use the balanced chemical equation to identify the number of carbon, hydrogen, and oxygen atoms in sugar. sugar + 12O2 → 11H2O + 12CO2 Sugar has carbon atoms. Sugar has hydrogen atoms. Sugar has oxygen atoms.
