C3 Photosynthesis. Plants which use only the Calvin cycle for fixing the carbon dioxide from the air are known as C3 plants. In the first step of the cycle CO 2 reacts with RuBP to produce two 3-carbon molecules of 3-phosphoglyceric acid (3-PGA).4 plants almost never saturate with light and under hot, dry conditions much outperform C3 plants. They use a two-stage process were CO 2 is fixed in thin-walled mesophyll cells to form a 4-carbon intermediate, typically malate (malic acid).
A molecular formula lists the numbers of the atoms of a specific element in a compound. A structural formula is a picture of how the atoms in a specific molecule are connectedâ¦, with each atom represented by its chemical symbol. For example, oxygen's molecular formula is O2. Its structural formula is O-O.
1) Chemical formula. It shows the types of atoms in the molecule, and, using subscripts, it shows how many of each type of atom is present. The Chemical formula of butane is C 4 H 10. 2) The structural formula of a molecule shows the symbol for every atom, and it shows every bond.3) The condensed structure of a molecule shows the symbol of every central atom and of each ligand or set of ligands bonded to a central atom.) A benzene molecule contains six carbon atoms in a closed ring, it has 3 carbon-carbon double bonds and six hydrogen atoms. Using ChemSketch or on a sheet of paper, write the chemical formula, condensed structure, structural formula, and line structure of benzene.
