HeeeeeeeeeeeelllllllllllllllllllllllpppppppppppppppppppppppppppppFind the statement about Fusion that is false.
Pie

Fusion releases less energy than fission

fusion most commonly combines heavy isotopes of hydrogen into helium.

Explanation:

Nuclear fusion is a form of reaction that involves the combination of two light nuclei to form one that is heavier in mass.

The other form is nuclear fission which is the splitting of heavier nuclei either spontaneously or when bombarded with other nuclei.

  • Nuclear fusion reactions in the core of stars powers the universe.
  • The reactions produces a huge amount of energy of a greater and massive order than fission reaction.
  • Small nuclei are involved in nuclear fusion and not the large ones.
  • Nuclear fusion degenerates into series of chain reactions that are extremely difficult to control.

How many moles are in 75.0 grams of nitrogen gas, N2?
Westkost [7]

<u>Given:</u><u>                                                                                                                       </u>

Mass of Nitrogen (N₂) gas = 75 grams

<u>Finding the number of moles of N₂:</u><u>                                                                     </u>

We know that the molar mass of N₂ is 28 grams/mole

Number of moles = Given mass / Molar mass

Number of moles = 75 / 28

Number of moles = 2.68 moles

Hence, there are 2.68 moles in 75 grams of Nitrogen Gas
