Answer:

The recommended way of preparing 100ml of 0.02 M from 2M NaOH in the laboratory is to obey the equation V1S1=V2S2.

Explanation:

According to the given question

  V2=100ml

  S2=0.02M

   S1= 2M

 Then V1=?

     We all know that V1S1=V2S2

                                 or  V1=V2×S2÷S1

                                  or  V1= 100×0.02÷2

                                  or  V1 =1  ml

It can be concluded that 1ml of 2M NaOH solution and 99 ml distilled water should be mixed to prepare 100ml of 0.02 M NaOH solution.

rusak2 [61]

Answer:

235/92U+10n→144/54Xe+90/38Sr+2/10n

Explanation:

  • The nuclear reaction for the neutron-induced fission of u−235 to form xe−144 and sr−90 is represented by;

235/92U+10n→144/54Xe+90/38Sr+2/10n

  • In nuclear fission reactions a heavy nuclide is split into two light nuclides and is coupled by the release of energy.

How does a chemist count the number of particles in a given number of moles of a substance?
jolli1 [7]
The chemist the count the number of particles (Atoms, Molecules or Formula Unit) in a given number of moles of a substance by using following relationship.

                              Moles  =  # of Particles / 6.022 × 10²³

Or,

                              # of Particles  =  Moles × 6.022 × 10²³

So, from above relation it is found that 1 mole of any substance contains exactly 6.022 × 10²³ particles. Greater the number of moles greater will be the number of particles.
