Answer: Heyo Kenji Here! Here's your answer- In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.
Explanation: Hope this helps!
Have a nice day!

Answer: Most ocean pollution begins on land
When large tracts of land are plowed, the exposed soil can erode during rainstorms. Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land.
Explanation:
Hope this helped. Goodluck! xD
There are three number of electrons lost by 1 mole of aluminium because aluminum has +3 charge on it.
<h3>What is cation?</h3>
When an atom loses electron, positive charge appears on the atom this is called cation. In this reaction we can see that aluminium has +3 charge which means that it loses 3 electrons.
So we can conclude that There are three number of electrons lost by 1 mole of aluminium because aluminum has +3 charge on it.
