I am a third year bioscience student studying at the University of Exeter. I have a passion for science and studied physics, chemistry and biology at A level.
I love helping people to understand a concept - it is very satisfying for both pupil and tutor when that lightbulb moment occurs! Whether this comes instantly from a basic explanation, or whether a more thorough process involving repeated examples and problem-solving is required, I will be on hand to assist you through the exciting learning process!
I very much look forward to hearing from all of you, let me know if you have any questions!

Ar of Magnesium = 24; Ar of Oxygen = 16
number of moles = mass divided by Ar
number of moles of Mg = 2.4/24 = 0.1
number of moles of Oxgen = 1.6/16 = 0.1
ratio of Mg to O = 0.1:0.1 = 1:1 So oxide produced is MgO
Work done (joules) = Force (newtons) x distance moved in direction of the force (metres)
Work done = 10 x 2 = 20J
Cold and low oxygen - minimises likelihood of organisms decaying
