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.
On a molecular level the density difference between the two is a result of lead having heavy, closely packed molecules while water's tend to be light and more loosely packed. Density is actually a measure of the mass or weight of the molecules in matter and their spacing.The biggest difference between lead and water is their molecular weights. But if you were to compare a liquid's density with a gas, it would be the spacing of the molecules that is important.ensity is actually a measure of the mass or weight of the molecules in matter and their spacing.
