What are the advantages and disadvantages of fission?
viktelen [127]

<u>Advantages of Nuclear Fission</u>

  • Nuclear fission provides cheapest energy . Almost 10% of electricity used in the world is obtained from the fission reaction
  • It offers a low-emission energy solution since there is no carbon dioxide gas emitted during the  nuclear fission reaction
  • A well controlled and maintained nuclear reactor can produce energy for 36 to 40 months so works for .
  • It is a reliable source of energy as energy is obtained from uranium which is available is plenty.
  • It provides very concentrations of energy as it can provide large amount of energy from small amount of fuel.
  • The reaction gives less annual mortality rate of any energy resource with 90 deaths per trillion kilowatt hours

<u>Disadvantages of Nuclear Fission </u>

  • It is dangerous and  also explosive.
  • It creates harmful and radioactive waste products.
  • It is not a renewable energy resource like solar and wind energy
  • It can develop long-term health issues for people exposed to then radioactive waves.
  • It involves high cost in installation of the reactors.

How many sulfur atoms are present in 25.6 g of Al2(S2O3)3
IgorC [24]

Given the mass of Al_{2}(S_{2}O_{3})_{3}=25.6 g

The molar mass of Al_{2}(S_{2}O_{3})_{3}=390.35g/mol

Converting mass of Al_{2}(S_{2}O_{3})_{3}to moles:

25.6 g Al_{2}(S_{2}O_{3})_{3}*\frac{1molAl_{2}(S_{2}O_{3}}{390.35 gAl_{2}(S_{2}O_{3}} =0.0656molAl_{2}(S_{2}O_{3}

Converting mol Al_{2}(S_{2}O_{3})_{3}to mol S:

0.0656mol Al_{2}(S_{2}O_{3})_{3}*\frac{6molS}{1mol Al_{2}(S_{2}O_{3})_{3}}=0.3936 molS

Converting mol S to atoms of S using Avogadro's number:

1 mol = 6.022*10^{23}atoms

0.3936mol S *\frac{6.022*10^{23}atoms S}{1 mol S}=2.37*10^{23} S atoms
