The temperature of the closed system is reduced while the pressure stays unchanged. Predict the effect on the position of equilibrium for this reaction. Explain your answer.
The pressure of the closed system is raised while the temperature remains constant. Predict the effect on the position of equilibrium for this reaction. Explain your answer.
Calculate the greatest mass of zinc oxide that can be produced from $4.23\,\text{g}$ of zinc carbonate.
Zinc oxide reacts with both aqueous sodium hydroxide and dilute hydrochloric acid, whereas carbon dioxide reacts only with aqueous sodium hydroxide. Explain why.
A solid sample of zinc carbonate reacts with dilute nitric acid to form a colourless solution and a gas is released as bubbles. Write the symbol equation for this reaction, including state symbols.
