This is fire ball ball type extinguisher which is design to release cloud of carbon dioxide and extinguish fire.This ball can be thrown from 15 mts away from fire and it takes 3-5 secs for reaction to take place and it covers about 64sqft area with carbon dioxide cloud.This extinguisher will save lives of the many firemen who loose there lives due to accidents.

9. Implications of this method
 Human safety
 Easy to use
 No Technical Knowledge required
 Less space required.

10. Reaction Involved
 Sulphuric acid and sodium bicarbonate reaction
2NaHCO3 + H2SO4 -> Na2SO4+ 2CO2
+H2o
 Aluminium Sulphate and sodium bicarbonate
Al2(SO4)3 +6 NaHCO3 = 3 Na2SO4
+2Al(OH)3 + 6 CO2
 Acetic acid and Sodium carbonate
CH3COOH + Na2CO3 ----> 2 CH3COONa +
H2O + CO2

11. Calculations
For the Reaction of Sulphuric acid
and Sodium bicarbonate
2NaHCO3+H2SO4 = Na2SO4 +
2H2O
+ 2CO2
Weight of NaHCO3 taken 168gms
Volume of H2SO4 taken 53.26 cm3
Calculation-
*No of moles = weight/molecular
weight
Weight =moles× molecular
weight
=2×84
Weight =168 gms of NaHco3
*Volume of sulphuric acid
for the other two reactions.
No of moles = weight/molecular
weight
Mass = moles×molecular
weight
= 1×98
Mass =98gms
Density = 1.84 gm/cm3
Volume = mass/density
= 98/1.84
= 53.26 cm3
Total amount of reactants=
98+168= 266 gms

12. Calculations
Enthalpy Calculation
∆H(NaHCO3)= -947.68 Kj/mol
∆H(H2SO4)= 1295.23 Kj/mol
∆H(CO2)= -393.51 Kj/mol
∆H(H2O)= -241.82 Kj/mol
∆H(Na2SO4)= -1387.1 Kj/mol
∆H®=∆H(reactants)-∆H(products)
=(2(-393.51)+2(-241.82)+(-
1387.1))-(2(947.68)+1295.23)
= -2057.63 Kj/mol
∆H= -2057.63 Kj/mol
Entropy Calculation
∆S(NaHCO3)= 102
∆S(H2SO4)= 2392
∆S(CO2)= 219
∆S(H2O)= 69.95
∆S(Na2SO4)= 149.6
∆S®=∆S(reactans)-∆S(products)
=(2(219)+2(69.95)+149.64)-
(2(102)+157)
=366.54 j/mol k
∆S=366.54 j/mol k
In the similar manner calculations
were conducted for other two
reactions was conducted.

material
 Design of the Fire Extinguisher
 Improve Impact distance

16. CONCLUSION
 Our proposed method is an innovative
way to use an fire extinguisher.
 The Enthalpy Calculation was conducted
to find out suitable pressure which will be
determine the material of construction.
 In this method we are constantly studying
and finding better way to reduce the cost
of this method so that it can be
economically feasible.
