used and extracted‚ we could run out of oil in 50 years. We need to conserve what fuels we have left and stop using them in our cars. Another big problem with burning fossil fuels‚ especially gasoline‚ is the damage it causes to the environment. Combustion of fuels in cars has been identified as the largest contributor to air pollution in the world.

alcohols. Within a molecule there are bond energies that are holding the atoms together. When the fuel combusts a chemical reaction takes place‚ this breaks the bonds‚ this requires energy‚ and makes new bonds this gives out energy. The energy differences between the two tell us how much energy was given out or taken in. We can show this on a graph. ENERGY CHANGES DURING A REACTION To find the bond energies in the molecule of the alcohol we have to look at the how much energy is in the separate bonds

Heats of Combustion of Alkanols Aim: To perform a first-hand investigation to determine the heats of combustion of selected alkanols. Hypothesis: It was predicted that methanol would have the highest molar heat of combustion‚ decreasing as the chains become longer. Equipment: • Three spirit burners containing methanol‚ ethanol and propan-1-ol respectively • Electronic scales • Water • 100ml measuring cylinder • Retort stand and boss-head clamp • Copper beaker • Thermometer Method:

In this lab‚ I calculated the heat of combustion of paraffin (candle wax) by burning a candle and holding a calorimeter (a soda can) filled with 98.7 mL of water above the flame. The heat released by the candle was absorbed by the water in the can. It was important to place the metal chimney around the candle so that minimal amounts of heat would escape; having too much heat lost to the atmosphere would cause extra error in the calculations. The assumption made was that all heat released from the

Intermittent Explosive Disorder A disorder of impulse control characterized by several episodes in which aggressive impulses are released and expressed in serious assault or destruction of property although no such impulsiveness or aggressiveness is shown between episodes. Intermittent explosive disorder is explosive eruptions which often results in verbal assaults‚ injuries‚ or destruction of property. Some symptoms include irritability‚ rage‚ increased energy‚ and racing thoughts‚ there is

Emulsion (SME) Explosives 1. SME is in fact a plant made product (emulsion matrix) which need only to be sensitized by entrapment of gas bubbles either by‚ chemical gassing or addition of substantial quantity of porous ammonium nitrate (AN) prills‚ to form explosive. 2. SMS is truly a Site Mixed Slurry explosive in the sense that all intermediate ingredients (nearly five) are brought to field in a specially designed Pump Truck and are mixed in a predetermined ratio to form explosive when the

Aim To find out difference in the heat of combustion for different types of alcohols. Hypothesis The higher the number of carbon atoms in an alcohol is‚ the higher the energy for the heat of combustion. Alcohol is a homologous series‚ a series of organic compounds with similar formula and chemical properties‚ and increase in molecular size and mass. When the equations for combustion of these alcohols are listed in the order of increasing number of carbon atoms‚ Methanol 1 CH3OH(l) + 3/2 O2(g)
