Thanks Mr Adura from ASIS.
Actually, the question is quite direct. There are many possible experiment plan. In fact, in student's textbook, students were asked to plan an experiment to study whether copper (II) sulphate affect the rate of reaction between zinc and sulphuric acid too.
Some useful guides when attempting this question:
- Give an example of acid & metal.
- How does metal react with acid? What is produced?
- How to do measure rate of reaction in an experiment? Hint: Rate of reaction is measured based on observable changes of quantity of reactant/product over a period of time.
- What are the required information/data to compare the effect of catalyst on the rate of reaction?
- Try to imagine the materials & apparatus required.
- Draw diagram to show the set-up of apparatus for the experiment.
- Think of the steps to set-up the apparatus till recording data required.
- Write down your plan.
- Recheck your plan. Especially for materials, apparatus & procedure & tabulation of data. Students do forget some important point.
Alkanes are saturated hydrocarbons. Alkane molecules consist only carbon and hydrocarbon atoms only. The atoms are joined by covalent single bond.
Some molecular models of few members of alkanes. Can you name them?
|5H students were happilly showing their molecular models after constructing few models of alkane members.|
|5C students are calculating number of atoms present in an alkane molecule.|
|Students are constructing the molecular model of decane in groups.|
|A student proudly showed her completed handout after using the molecular model of alkane.|
