How does the Relative Molecular Mass change in heat combustion of an alcohol? :: GCSE Chemistry Coursework Investigation
How does the Relative Molecular Mass change in heat ignition of a liquor?    Arranging    Presentation    ============    As liquor consumes in air it gives out vitality as warmth and light. I am    going to examine how the vitality yield of a liquor in ignition    changes, with expanded relative atomic mass, or RMM. RMM is the    total of the nuclear masses of each iota in the particle. Utilizing the    alcohols: Methanol, Ethanol, Propan-1-ol, Butan-1-ol and Pentan-1-ol,    I will design, and complete a test that tests the expectation    underneath.    ======================================================================    Expectation And Theory    =====================    In the ignition of alcohols in air, the liquor responds with oxygen    atoms, to make carbon dioxide and water. Numerous bonds are broken    in the process spending vitality. Simultaneously, the molecules transforming    into the new particles of carbon dioxide and water give out vitality. In    the burning of alcohols, the vitality made, when framing bonds    will consistently be more that what is lost, when breaking bonds, this gives    us abundance vitality. This vitality is given out fundamentally as warmth, yet in addition    as light and sound. As vitality is given out it is called an exothermic    response. In the event that the inverse were valid, it would be an endothermic    response. It is never conceivable to figure accurate vitality change by    experimentation because of errors and vitality squander, so we use bond    vitality computations give the specific hypothetical vitality change.    Bond vitality computations show that the higher the RMM the more vitality    will be delivered for a similar load of fuel (RMM is the entirety of the    nuclear masses of each iota in the particle). This is on the grounds that as the    RMM builds there are more iotas and accordingly, more bonds to be    broken and afterward made. As, when consuming alcohols, this procedure gives    out vitality, the more bonds experience this procedure, ie as the RMM    expands the more vitality ought to be discharged. The figurings too    recommend that for each carbon iota you add to the chain of a liquor    the vitality out should increment by    618 Kj/mol. I anticipate at that point, that as the RMM goes up then the vitality    change will get progressively increasingly negative for example more vitality is given    off. The RMM will be relative to the last vitality made as both    should increment by a similar number each time, (RMM by 14 as one C and    2 H iotas are included, and the vitality out by 618KJ/mol). This will    along these lines bring about a straight-line on the diagram. The bond vitality    counts show how much vitality ought to be discharged, representing    trial errors in any case, I anticipate that the trial yield should    be significantly less.    Proposed Method    I am going to test how the vitality yield per mole in the burning of
