Write each of the following statements as a balanced chemical equation:
1) When hydrogen sulfide gas is bubbled through a solution of lead(II) nitrate, a black precipitate of lead (II) sulfide is formed along with nitric acid.
2) When barium hydroxide reacts with nitric acid it forms barium nitrate (used to create green colored pyrotechnics) and water.
3) When sulfur trioxide gas reacts with water, a solution of sulfuric acid forms.
4) When solid mercury(II) nitrate is heated, it decomposes to form solid mercury(II) oxide, gaseous nitrogen dioxide, and oxygen.
5) Copper metal reacts with hot concentrated sulfuric acid solution to form aqueous copper(II) sulfate, sulfur dixode gas, and water.
Challenge Question: Pick three of the equations you balanced and draw a molecular view representation of the balanced reaction occurring, show both the reactants and the products. Pay attention to the structure and shape of all species.
