When you are ready, add a 3 cm strip of magnesium ribbon to the flask, put the bung back into the flask as quickly as you can, and start the stopwatch. Fill the other measuring cylinder with water, and make sure that it stays filled with water when you turn it upside down. Buckminsterfullerene is an allotrope of carbon with a formula of c60.

In this experiment there will only be one independent variable this is the molarity of the hydrochloric acid. This collection of over 200 practical activities demonstrates a wide range of chemical concepts and processes. Prediction for independent variable in my experiment i will have the hydrochloric acid as the independent variable.

The exothermic reaction had affected the outcome of the reaction causing more collisions therefore making the results less accurate. However the acid is in excess, so it is mainly the loss of magnesium (surface area becomes smaller) that causes the change in the rate. I had recorded all the relevant information that i needed from my experiment onto a labelled table, which then i had created my graphs from.

The way i will decrease the molarity of the hcl is by diluting a certain proportion of water into the hydrochloric acid while decreases the amount of hcl. It is not enough for the particles to collide, the bonds between the atoms they have to be broken before new molecules can be produced. Record the volume of hydrogen gas given off at suitable intervals (eg 10 seconds).

It is best if the students work in pairs because setting up and starting the experiment requires more than one pair of hands. All my graphs approve that my evidence are accurate because neither of the graphs have an anomalous point even though some plots are slightly off the best fit line. This can be seen on the graph, as the slope becomes less steep and then levels out when the reaction has stopped (when no more gas is produced).

This would let me know how different chemicals influence the rate of reaction and this can also help me to compare the results, which would give me a far better conclusion. A metal wire- a metal wire which has a high melting point created out a metal such as iron and is made into a wire with diameter of a about 2mm but yet is malleable and yet maintains high strength. So i chose different amounts for my experiment, 40ml hcl and 5g caco3 prediction in the preliminary work i only used one sample so i cannot predict which of the to samples will be purer. Pour the acid into the 100 cm set up the apparatus as shown in the diagram. Dependent and independent variables my dependent variable in this experiment will be the temperature and the dimension of the magnesium ribbon.

This practical chemistry resource was developed by the nuffield foundation and the royal society of chemistry. This is a resource from the practical chemistry project, developed by the nuffield foundation and the royal society of chemistry. One student can add the magnesium ribbon to the acid and stopper the flask, while the other starts the stopclock.

This shows that the reaction is fastest at the start. All my evidence that i had obtained from my experiment are accurate for instance my tables and graphs. .

This is because mg can easily loose its 2 outer electrons, the result of this is that it will react rather vigorously as two different particles react. Marker pen to mark the level of water every 10 seconds. I would extend my investigation by carrying out more concentrations of hcl and maybe using other chemicals such as sodium thiosulphate to contrast the rate of reaction between the two.

The hydrochloric acid should be about 1m for a reasonable rate of reaction. But these are very expensive and are probably best used by the teacher in a demonstration. In addition, sea turtles may swallow the bags and it becomes lodged in their throats until it wraps around the insides of the turtle (as its indigestible).
