What is a fuel
A substance which can be burned to produce energy
Explain how an uncontaminated dry sample of a salt can be obtained
Repeat experiment without an indicator and evaporatr off the water
Suggest why the use fo a catalyst makes a process more economical
allows the product to be produced mroe qucikly
Suggest what might be produced when methane is bruuend in a limited supply of oxygen
carbon monoxide
Suggest why the use of a draught sheild and a copper can can improve the reliability of the results in a combustion experiment
Copper conducts heat better than a glass beaker and the draught sheild prevents heat being lost to the surroundings
What are the uses for carboxylic acids
preservative, cleaning product
What is an exothermic reaction
Reaction which releases heat to the surrounding
What is an endothermic reaction
Reaction which absorbs heat from the surrounding
Name the two substances produced when ethanol burns in a plentiful supply of oxygen
Carbon dioxide and water
Suggest why a reaction being ectothermic is an advantage
Heat is produced during the reaction once the reaction starts the external heat can be removed and so save money
