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.

Given that a theoretical yield for isolating Calcium Carbonate in this experiment would be 100%. From that information and based
Stels [109]

Answer:

It's well Explained below.

Explanation:

First of Excess product of CaCO_3 would be produced due to the fact that there would not be enough CaCl_2 to react with Na_2•CO_3. The main purpose of having stoichiometric quantities is for us to know the correct amount or near the correct amount of each reactant in order to create a product that will be close to the theoretical amount and thus have a higher percent yield.

Activity: A Ferris wheel with a diameter of 60.0 m is moving at a speed of 2.09 m/s. What is the centripetal
GarryVolchara [31]

Answer:

Centripetal acceleration of the wheel is 0.145\ m/s^2.

Explanation:

We have,

Diameter of a Ferris wheel is 60 m

Radius of the wheel is 30 m

Speed of the wheel is 2.09 m/s

It is required to find the centripetal  acceleration of the wheel. The formula of centripetal acceleration is given by :

a=\dfrac{v^2}{r}\\\\a=\dfrac{(2.09)^2}{30}\\\\a=0.145\ m/s^2

So, the centripetal acceleration of the wheel is 0.145\ m/s^2.
