Sulfur is a non-metal. Describe three physical properties that are characteristic of non-metals.
Name one source from which sulfur is obtained.
Heating carbon with sulfur produces carbon disulfide, CS$_2$. $\text{C} + 2\text{S} \rightarrow \text{CS}_2$ Complete the energy level diagram for the formation of carbon disulfide by adding these formulae to the diagram: • C + 2S • CS$_2$
Explain, using information from the energy level diagram, how you know that this reaction is endothermic.
Carbon disulfide is a liquid at room temperature. Describe the spacing and movement of the particles in liquid carbon disulfide.
Hydrogen sulfide is a gas which changes filter paper soaked in aqueous lead(II) ethanoate from white to black. Hydrogen sulfide is slightly soluble in water. A long glass tube is arranged as shown. At first, the filter paper soaked in aqueous lead(II) ethanoate remains white. After a short time, the filter paper soaked in aqueous lead(II) ethanoate turns black. Explain these observations using the kinetic particle model.
Sulfur dioxide is an air pollutant. Give one harmful effect of sulfur dioxide on buildings.
Sulfur dioxide is used to bleach paper. Give one additional use of sulfur dioxide.
