Answer: The bold staircase in the periodic table allows us to classify which elements are metalloids.

Explanation: Additionally, it acts like a "divider" that allows us to properly distinguish the metals from the non-metals in the periodic table.

if a scientist creates a new rock like substance in a laboratory, why wouldnt this type of material be classified as a true mine

ad-work [718]

The reason why it is not considered this is because the material was made in a lab, not through nature, which is what is required to be considered as a true mineral.

If you are using 3.00% (mass/mass) hydrogen peroxide solution and you determine that the mass of solution required to reach the

Maurinko [17]

Answer:

0.004522 moles of hydrogen peroxide molecules are present.

Explanation:

Mass by mass percentage of hydrogen peroxide solution = w/w% = 3%

Mass of the solution , m= 5.125 g

Mass of the hydrogen peroxide = x

$w/w\% = \frac{x}{m}\times 100$

$3\%=\frac{x}{5.125 g}\times 100$

$x=\frac{3\times 5.125 g}{100}=0.15375 g$

Mass of hydregn pervade in the solution = 0.15375 g

Moles of hydregn pervade in the solution :

$=\fraC{ 0.15375 g}{34 g/mol}=0.004522 mol$

0.004522 moles of hydrogen peroxide molecules are present.
