Created with Fabric.js 1.4.5 i-ON Mac | Early Adopter | Gadgets Unique Features - Car weight : 1.35 kg- car motor powered by electrolysis- Iodine clock as stopping mechanism - Perspex : Light weight car body hold the iodine clock and battery container to avoid spillage- Wide car base : avoid spillage and increase car stability- modify front part of the car to move in straight line- tyres 5cm diameter, 2cm thick : stable movement and avoid car basement touching the ground- Wet Sponge : absorb hydrogen gas released- battery with with lid : avoid leakage - 150˚ triangle shaped bumper : allow golf ball move in slant direction - Electrolysis using magnesium and coppers strips with sulfuric acid as electrolyte Mg(s) Mg2+(aq) + 2e Cu2+(aq) + 2e Cu(s) Mg(s) + Cu2+(aq) Mg2+(aq) + Cu(s)- Parallel circuit : 6 cells- Voltage generated : 2.71V per cell- total voltage : 16.26V The excess I3- forms a complex solution with starch.After a short time delay, the liquid slowly turns to a shade of dark blue.The photoresistor is unable to detectlight, resistance in the circuit increased,triggering therelay to open the motor circuit and thus the car stops.H2O2 (aq)+3I (aq)+2H+ (aq) I3 (aq)+2H2O (l) (slow)I3 (aq)+2 S2O32 (aq) 3 I (aq)+S4O62 (aq) (fast) - Motor powered Car RM65.90- Photoresistor RM17.90- 9V batteries RM10.00- Magnesium strips RM44.60- poster RM20 TOTAL RM158.40 ELECTROLYSIS DRIVEN CHEM E-CAR - hydrogen gas are soluble in water the gas released is absorbed by wet sponge- sulfuric acid and hydrogen peroxide are handle with care and dilute fume chamber- all wastes are handle with care according to the MSDS Testing Results Introduction Mg & Cu Iodine Clock Environmental &Safety Aspects Economy Apects TENG FOO LIM FUNG YUN RUTRACY LAU FANG TING PUA HONG LONG From the data collected, the velocity and momentum of the car is depends on the car load. The greater the load, the larger the momentum to hit the golf ball. Chem E-Car 2015 UKM
