What is a saturted solution
andrew-mc [135]

Answer:

Please find the definition and further explanation below

Explanation:

Based on the ability for the solvent (liquid substance) to dissolve a solute (solid substance), a solution can either be unsaturated, saturated or supersaturated. A SATURATED SOLUTION is that which contains the maximum amount of solute a solvent can possibly dissolve.

In other words, a saturated solution can no longer dissolve anymore solute, and hence, any further solute added forms crystals or makes the solution supersaturated.

Which of the following statements best describes the properties of aluminum-28?
Contact [7]

d. When aluminum-28 undergoes beta decay, silicon-28 is produced.

Explanation:

When the nuclei of aluminium-28 decays, it produces silicon- 28:

    Aluminium    ²⁸₁₃Al

    Silicon 28      ²⁸₁₄Si

    beta particle     ⁰₋₁\beta

       

           ²⁸₁₃Al        →          ²⁸₁₄Si      +        ⁰₋₁\beta

This way, the mass and atomic number are conserved.

Conservation of mass number:

                28 = 28 + 0,  28 = 28

                 13 = 14 -1 ,       13 = 13
