Balanced equation: C₂H₄ + 3O₂ → 2CO₂ + 2H₂O
O₂ required: 3/1 x moles C₂H₄ = 3/1 x 6.51 = 19.53 moles
Answer/Explanation:
Differences in temperature in the mantle cause convection currents. If it weren't for these convection currents wouldn't exist.
Answer:
a) C3H8 + 502 ----> 3CO2 + 4H20.
combustion reaction
b) HBr + KOH ----> KBr + H2O
Neutralization reaction
c)AlBr3 + 3 KCl----> 3 KBr + AlCl3
Redox reaction
Things that are less dense will go above things more dense. In convection warmer, less dense air rise above cooler, more dense air.
