You can continue in a broader context by introducing some background theory and descriptions of the factors or VARIABLES which may have an effect on the rate of the reaction you are studying include briefly factors which might not apply.

This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction. They replaced the former CSE and O-Level qualifications, uniting the two qualifications to allow access to the full range of grades for more students.

A BRAINSTORM outline of a whole investigation is outlined below, it is not meant to be prescriptive, but can form the basis of aiming for a high mark and hopefully give you plenty of ideas.

Chemistry (Single Science)

There are a few outliers in my results. Chemistry Practical Endorsement Course Specification: Planning - the theory and your experiment design! The state symbol for sulphur dioxide is aq not g because it is dissolved in water as its original state would be too toxic and corrosive for me to use safely.

There is one outlier in 2M concentration. Using white paper helped the marking to stand out. I could have use a colorimeter to identify colour changes in the products. The bars for 3M, 4m and 5M do not overlap. Most qualifications from the English boards are also available, with the exception of English language and the sciences, due to requirements for speaking and practical assessment, respectively.

In the case of the sodium thiosulphate - acid reaction, you can leave the thermometer in the flask and take the temperature at the end, then use an average for the temperature of the reaction.

If a gas is formed, there are at least two ways of collecting a gas e.

Chemistry (Single Science)

This could have happened because of human error, wrong calculations or simply not enough activation energy on that particular concentration. I made sure that I had everything before I started.

The timer was stopped when in see the black cross through the cloudy solution could no longer. If a gas is formed, there are at least two ways of collecting a gas e. The highest grade, 1, was considered equivalent to an O-Level C grade or above, and achievement of this grade often indicated that the student could have taken an O-Level course in the subject to achieve a higher qualification.

A few health and safety ideas on risk assessment AIM for a high investigation-project mark - you have nothing to lose for your assessment! I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask.The Reason to Choose Us for Your Science Coursework.
