About me

About Me:

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!

The Sessions:

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!

Questions Sarah has answered

Calculate the enthalpy of formation of water.Is the reaction an exothermic or endothermic reaction?

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:

H=0kJ/mol

O2 =0kJ/mol

H2O=-285.83kJ/mol

From the equation given earlier, we can put the numbers in and get

Enthalpy= -285.83-(0+0)

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!
