Expert Solution

There are four major biomolecules present in plants - - carbohydrate , lipid, protein and nucleic acid.

Carbohydrates are the poly hydroxy aldehyde or ketone compound. The monomer of carbohydrate is sugar which made up of - - carbon, hydrogen and oxygen.

Lipid comprises of fatty acid and their derivatives. A fatty acid consists of a straight chain of a number of carbon atom with hydrogen atom along the length of the chain and a carboxyl gruop (-COOH) at one end.

Proteins are made of 20 different amino acids arranged in a form of polypeptide chains. An amino acid comprises of - - a central carbon atom, a hydrogen atom, an amino gruop (-NH2), a carboxyl gruop (-COOH) and a side chain (R group) consisting of varying atoms.

Nucleic acid refer to the genetic material and are of two types - DNA and RNA. The monomeric unit of nucleic acid is nucleotide which composed of a nitrogen base, pentose sugar and phosphate.

So, from the above question the lists of elements that are present in all biomolecules in plants are - - oxygen, hydrogen and carbon..

When coal is burned, the sulfur present in coal is converted to sulfur dioxide (SO2), which is responsible for the acid rain phenomenon. S(s) + O2(g) → SO2(g) If 4.82 kg of S are reacted with oxygen, calculate the volume of SO2 gas (in mL) formed at 29°C and 1.16 atm. . Calculate the mass in grams of hydrogen chloride produced when 5.65 L of molecular hydrogen measured at STP reacts with an excess of molecular chlorine gas. H2(g) +...
