Alkanes, alkenes and alkynes are simple hydrocarbon chains with no functional groups, with alkanes being the simplest organic compounds in organic chemistry. Butyl butanoate is a clear, colourless liquid that has pleasant aroma that is used to add fruity pineapple flavours. Outline the steps required for the synthesis of butyl butanoate in a school laboratory.
Support your answer with a diagram and a chemical equation using structural formulae. Many health problems that make our body too acidic or too basic are usually linked to the pH of blood. Hyperventilation is a condition in which you have rapid and deep breathing with more exhaling than inhaling. Explain the effect of hyperventilation on the pH of blood. Support your answer with at least ONE chemical equations. Methanol can be synthesised from carbon monoxide which can be produced from a reverse water-gas shift reaction involving only gaseous components.
At time T 1 , some carbon dioxide was added to the system. Sketch the concentrations after time T 2 for all species. Explain how industry could maximise the production of carbon monoxide. The information in the table shows how the solubility of calcium hydroxide is affected by temperature. Predict if a precipitate of calcium hydroxide will be observed in the resultant mixture.
Support your answer with relevant calculations. Explain the treatment of iron III contaminated tailings using calcium hydroxide with reference to solubility. Include relevant chemical equation. Formic acid HCOOH is an antibacterial agent that is also found in nature in most ants and stringless bees as an agent used on their prey or to defend the nest.
Calculate the p K b of the formate ion. Ethanol-blended fuel is widely used around the world as a biofuel additive for gasoline in vehicles. Calculate the pOH of the resulting solution after In pyrometallurgical processing of copper II carbonate minerals, the ores are thermally decomposed in the roasting process to form copper II oxide.
The copper II oxide can then be dissolved in sulfuric acid to give the corresponding copper II salt which can be refined further to give copper metal. In laboratory, The resulting solution was made up to mL with distilled water. A colorimeter was used to measure the absorbance of the final solution to be 0. Define the term amphoteric. Include at least TWO balanced chemical equations in your answer. Primary, secondary and tertiary alcohols of the same carbon length have quite different boiling points.
Explain the difference in boiling point of these organic compounds, showing all intermolecular forces. Support your answer with diagrams.
