The element has 83 electrons
Answer:
The answer is
<h2>8.4 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass = 88.2 g
density = 10.5 g/cm³
The volume is

We have the final answer as
<h3>8.4 mL</h3>
Hope this helps you
The oxidation half reaction of the reaction given above would be: Ca → Ca + 2e−. Oxidation is the loss of electrons of an element while its counterpart is called the reduction which gains the electrons that has been lost. Hope this answers the question.
