Two electrons 1 and 2 move along antiparallel paths separated by a distance of 10 nm, traveling at speeds 4.5 x 10^7 m/s and 8.0 x 10^6 m/s.
part a) what is the magnitude of the magnetic force exerted by electron 2 on electron 1? express your answer with the appropriate units.

The magnetic force on electron 1 by electron 2=

Explanation:

We are given that

Distance between two electrons=10 nm

Speed of electron 1= m/s

Speed of electron 2= m/s

We have to find the magnitude of the magnetic force exerted  by electron 2 on electron 1.

Magnetic force on electron 1 by electron 2

)

Substitute the values in the given formula

The magnetic force on electron 1 by electron 2=

The magnetic force on electron 1 by electron 2=

Hence, the magnetic force on electron 1 by electron 2=

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
