For the reaction to take place the energy of the reactants must reach to the energy level of the products:
we have 900 J in the reactants and 9000 J for the products so the reactants need 8100 J to reach to the value of energy of products (900 + 8100 = 9000)
So the correct answer is C. <span>The reaction absorbs 8100 J of energy from the surroundings as it proceeds. </span>

Answer:
Gene is the basic unit of inheritance.
Answer:
Option D.
Explanation:
When an element undergoes an alpha decay, the resulting daughter nuclei will have a decrease of 4 in the mass number and a decrease of 2 in the atomic number.
Considering the options given, only option D conform to the above illustration.
Therefore, option D represents alpha decay.
Fusion, fission, and radioactive decays of unstable nuclei, involve release or absorption of energy. The total number of neutrons plus protons does not change in any nuclear process. are not conserved, but the total number of protons plus neutrons is conserved.
