Which substance is most likely a lipid? long chains of molecules composed of carbon, hydrogen, and oxygen atoms compounds that are composed of amino acids and atoms, such as nitrogen, that are joined together by peptide bonds a nonpolar organic compound that is insoluble in water a molecule that constitutes the building blocks of more complex molecules that are soluble in water

-

A non polar organic compound that is insoluble in water

Explanation: -

Lipids are fatty acids and their derivatives. They are hydrophobic in nature meaning insoluble in water. They store energy and used for signaling.

They are generally oils, steroids and waxes. The endoplasmic reticulam of the cell is the main site for lipid synthesis for both plants and animals.

Thus lipids are fatty acids and their derivatives. They are insoluble in water.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
