What type of radiation is emitted during a nuclear process in which a nucleas with a greater atomic number is formed?
neonofarm [45]

Answer:

<em>Neutron (¹₀n)</em>

Explanation:

<em>Nuclear Fission: </em>This is a process in which two or more light nuclei fuse or combine to form a heavier nucleus with a release of energy and radiation.

<em>Neutron: </em><em>A neutron is located in the nucleus of an atom, It has a neutral charge, The mass of neutron is 1.660540 x 10⁻²⁷ kg</em>

Therefore The type of radiation emitted during a nuclear process in which a nucleus with greater atomic number is formed is <em>Neutron (¹₀n)</em>

Write equations to show whether the solubility of either of the following is affected by pH:(b) Ca₃(PO₄)₂.
Vera_Pavlovna [14]

<u>The </u><u>pH </u><u>of the solution is also </u><u>increased.</u>

<u></u>

What is pH and its importance?

  • pH is an important quantity that reflects the chemical conditions of a solution.
  • The pH can control the availability of nutrients, biological functions, microbial activity, and the behavior of chemicals.
  • The pH is then calculated using the expression: pH = - log [H3O+].

  • The solubility of an ionic compound is affected by the hydronium ion concentration.
  • Addition of H₃O⁺ to the anion of a weak acid, increases the solubility of the ionic compound.

Therefore, the pH of the solution is also increased.
