Degree: Chemistry (Bachelors) - Liverpool University
I am a 2nd year Chemistry student at The University of Liverpool and I have always had a real passion and love for all things 'science' and hope that my tutorials will instil that love in you, too. As well as my love of science, I also have a great love of teaching and hope to pursue it in a future career!
I am very patient and friendly. I have been teaching drama since I was 16, so have a lot of experience teaching, with people as from the ages of 6-16. During my summer breaks, I worked in my local primary school and also volunteered in several secondary schools teaching science in classroom settings. This ties in with my degree as I have taken a module in my second year entitled Science Communication which brings secondary school students into University settings and teaches them fundamental ideas in science. I received very good feedback from all my lessons delivered which showed in my final grade.
On a more personal level, I also understand how stressful exam situations can be and have struggled with them in the past. Although my C in physics may not look exceptional on paper, I feel I should point out, I got A/B's on all but one exam which did lower my mark, but I will strive to ensure this doesn't happen to you!
During the sessions, you will be in charge of what we cover. In science basic understanding is key, so before we do exam questions, we will focus on this.
I will try and use as many different ways (diagrams, words, analogies) as possible to explain a concept until you are confident enough that you can explain it to me. However, if you feel like something isn't clicking. Please tell me and I will try my best to change it.
I hope the sessions will be fun! A lot can be achieved in 55mins especially if it is made enjoyable.
What comes next?
If you have any questions, send me a 'WebMail' or book a 'Meet the Tutor Session'! (both accessible through this website). Remember to tell me your exam board and what you're struggling with.
I look forward to meeting you!

The reaction is as follows:
2H2 + O2 -> 2H2O
This means that for every 2 molecules of Hydrogen gas, one molecule of Oxygen is needed to make 2 molecules of water
To calculate the enthalpy of this reaction, we use the equation:
Enthalpy of reaction = (Enthalpy of products) - (Enthalpy of reactants)
The Enthalpy of Formations for each molecules are:
From the equation given earlier, we can put the numbers in and get
This means Enthalpy of formation of water=-285.83kJ/mol
So how can we tell if its endothermic or exothermic?
It's really quite simple. If there is a negative (minus) sign, the reaction is exothermic, and if there is a positive (plus) sign, the reaction is endothermic!
Therefore we can see, our answer has a negative sign so is exothermic!
