Cool Sci question <take your best shot>

You’re stuck on an island and you must find a way to power a rowboat. Take a look at the following four items.

 

Hydrogen Peroxide

Vinegar (acetic acid)

Baking Soda

A pinch of manganese dioxide

 

Using the materials provided, design a chemical reaction that could be used to power a rowboat across the ocean. Take your best shot

well.

the manganesse diox and the h2o2 mixed will make oxygen, the remaining 2 will make co2. both will be liberated as gasses.

 

however, since it`s a ROW boat, wouldn`t it be better to leave them all as their excess weight and just ROW away with bits of wood as oars or however you spell those paddle thingies you displace water with?

 

failing that, and you MUST power it, use the acid and the H2O2 and wood alc to make an organic peroxide rocket engine :)

use the bicarb and any remaining acid as a fire extinguisher made from a coconut shell :))))

 

 

have a nice day :P

Forgot to ask, who can also write the word equation and balanced chemical equation for all possible reactions?

k... we know dat Vinegar and baking soda make CO2 and that H2O2 and MnO2 make oxygen... but the point is... wuld it be efficient to get off the island,... i mean if you really want to power the boat by expansion of gases, why not get a huge@$$ bottle rocket (6 KNO3 + 2 C11H22O11) and light her off... even then you probably still couldnt get enough power...

 

ok i dont know if this is right... but the chemical equation go as follows between vinegar and baking soda...

 

C2H4O2 + NaHCO3 --> CO2 + H20 + NaC2H3O2

 

that should be balanced...

 

Acetic acid + Sodium Bicarbonate --> Carbon Dioxide + Water + Sodium Acetate

 

cheerz (and by the way... id use the oars... theyll get you alot further...)
