The temperature in the closed system is raised while the pressure remains constant. Predict the effect on the equilibrium position for this reaction. Explain your answer.
The pressure in the closed system is reduced and the temperature is held constant. Predict how the equilibrium position for this reaction changes. Explain your answer.
Calculate the greatest mass of zinc oxide that can be obtained from $25.5\,\text{g}$ of zinc sulfite.
Zinc oxide can react with both aqueous sodium hydroxide and dilute hydrochloric acid, whereas sulfur dioxide reacts only with aqueous sodium hydroxide. Explain why.
Solid zinc sulfite reacts with dilute nitric acid to produce sulfur dioxide gas, an aqueous zinc salt and a colourless liquid. Write the symbol equation for this reaction, including state symbols.
