There are 337.23 × 10²³ atoms in 4 moles of aluminum sulfite Al₂(SO₃)₃.
Explanation:
The questions ask how many atoms are in 4 moles of aluminum sulfite Al₂(SO₃)₃?
To answer this we use the Avogadro's number to devise the following reasoning:
if in 1 mole of Al₂(SO₃)₃ there are 14 × 6.022 × 10²³ atoms
then in 4 moles of Al₂(SO₃)₃ there are X atoms
X = (4 × 14 × 6.022 × 10²³) / 1 = 337.23 × 10²³ atoms

The process of absorption of carbon dioxide by the oceans is known as ocean acidification. This occurs when ocean water absorbs carbon dioxide and the carbon dioxide combines with water to form carbonic acid. This carbonic acid serves to increase the hydrogen ion concentration in the water, and therefore reduce the pH.
Increased ocean acidification is harmful for marine life, as marine animals can survive only in a small specific pH range.
By the number of Electrons in the valence shell if 1=group 1 if 2 its group 2 and so on Valence means outermost shell
