Answer:

The island of stability is a term from nuclear physics that describes the possibility of elements with particularly stable "magic numbers" of protons and neutrons. This would allow certain isotopes of some transuranic elements to be far more stable than others, that is, decay much more slowly.

A 58.33-g sample of milk of magnesia, Mg(OH)2, always contains 24.31g of magnesium, 32.00g of oxygen, and 2.02g of hydrogen. Fin

ASHA 777 [7]

The mass percentage of each element in the milk of magnesia is, 41.68% Mg, 54.86% Oxygen, and 3.46% Hydrogen elements

Give the total mass of a sample of milk of magnesia Mg(OH)₂ as 58.33 g

We are to calculate the percentage by mass of each element

$\% mass =\frac{mass \ of \ element}{mass \ of \ sample} \times 100$

For Magnesium:

Mass of magnesium = 24.31g

$\% mass \ of \ Mg = \frac{24.31}{58.33} \times 100\\ \% mass \ of \ Mg =\frac{2431}{58.33} \\ \% mass \ of \ Mg = 41.68\%$

For oxygen element:

Mass of oxygen = 32.00g

$\% mass \ of \ O_2 = \frac{32}{58.33} \times 100\\ \% mass \ of \ O_2 =\frac{3200}{58.33} \\ \% mass \ of \ O_2 = 54.86\%$

For the hydrogen element

Mass of hydrogen = 2.02g

$\% mass \ of \ H_2 = \frac{2.02}{58.33} \times 100\\ \% mass \ of \ H_2 =\frac{202}{58.33} \\ \% mass \ of \ H_2 = 3.46\%$

Hence the mass percentage of each element in the milk of magnesia is, 41.68% Mg, 54.86% Oxygen, and 3.46% Hydrogen elements.

Why is HCI a strong acid and HCIO a weak acid?

valkas [14]

Strong Acid: dissolves and dissociates 100% to produce protons (H+) 1. seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. ... Weak Acid: dissolves but less than 100% dissociates to produce protons (H+) 1.
