Eleanor wants to show her class a comparison of melting
rates between two different solids when heat is applied. A graph would be more
suitable than a table to show her data because the she can see the trend line
of the effects of melting than the table.

The last option: include all of the known electrons for the adam it represents
that statement is not true because Lewis dot structures only show valence electrons
This problem is providing information about a reaction between magnesium and hydrochloric acid. However, the moles of the latter are required given 50 cm³ of a 0.2-M solution, making this problem more about the application of molarity. At the end, the answer turns out to be 0.01 mol.
<h3>Molarity:</h3>
In chemistry, we use units of concentration in order to represent the relative amounts of solute and solvent in a solution. More specifically, molarity relates the moles of the solute with the liters of solution according to:

Thus, since this problem asks for the moles of hydrochloric acid in 50 cm³ of a 0.2-M solution, we must first calculate the volume in liters with:

To finally solve for n, moles, to obtain:
