2CH3OH + ?O2 2CO2 + 4H2O
9. How many molecules of O2 are needed to balance the chemical equation?

c. 3
d.4

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
