Write a balanced chemical equation for each reaction. 11. NO(g) + O;(g) → NO,(g) 14. C,H,«g) + O;(g) → CO2(g) + H¿O(g) 20. Carbon dioxide gas, liquid water, and an aqueous solution of sodium chloride form when hydrogen chloride gas is bubbled through a solution of sodium carbonate. 17. Propane, C,H;(g), burns in the presence of oxygen gas to form carbon dioxide gas and water vapour. 5. When aqueous solutions of silver nitrate and sodium chloride are combined, the reaction produces an aqueous solution of sodium nitrate and a precipitate Write a skeleton equation for each chemical reaction. Indicate the state of each reactant and product in the skeleton equation. Remember that the following seven elements are diatomic: hydrogen, H;(g); nitrogen, N2(g); oxygen, O,(g); fluorine, F;(g); chlorine, A;(g); bromine, Br3(€); and iodine, I(s). of silver chloride. 1. Gaseous hydrogen and oxygen react to form gaseous water. 3. Solid potassium chlorate breaks down to form solid potassium chloride and oxygen gas. 9. Solid aluminum and gaseous fluorine form when solid aluminum fluoride breaks down.
