Cobalt-60 can make fruit flies infertile. justify the uses of above radioactive mentioned.

The uses of Cobalt-60 are described below.

Explanation:

Cobalt-60 is known to cause infertility in fruit flies but it is actively used in the health as well as industrial sectors.

In the health industry, Cobalt-60 is used for cancer radiography treatment. The radiography is generally done with Gamma Knife. This instrument works by generating a high dose of the Cobalt-60 radiation on the tumor area, protecting the other healthy tissues.

For industrial usage, The EPA has established a certain limit range for the uses of this man-made radioactive element.  It is used in the manufacturing industry to make steel. In the food industry, Cobalt-60 is used to prevent food spoilage as it kills microbes.

  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
