When the number of carbon atoms was 12, the contact angle and the wetting heat reached the maximum values after alkanes interacted with coals. The yield of the clean coal, the combustible material recovery and flotation perfect indicators of the isododecane were higher than those of the dodecane...
The names of the higher-molecular-weight compounds are derived from Greek numbers that indicate the number of carbon atoms in the chain. Each name has the suffix -ane, which identifies the compound as an alkane. Table 4.1. Names of Normal Alkanes Number of Carbon AtomsNameMolecular Formula 1...
What is the atomic mass number of carbon-13? If an atom has an atomic number of 8, how many protons will it have? What is darmstadtium's atomic mass? What is effective atomic number? Is the atomic number equal to the number of electrons?
distribution curves in a mass spectrum corresponds to the number of different configuration of clusters,so we can correlate the mass spectra of carbon clusters with their structures.根据出现在质谱中的各种大小的碳原子簇的相对丰度,分析了由激光产生的碳原子簇离子的统计分布,研究了这些统计分布与碳原子簇...

Subsequently, these canonical building blocks are cyclized by terpene synthases (TPSs) to form hydrocarbons with the corresponding number of carbon atoms. Previously, we expanded the chemical diversity of terpenoids by synthesizing C11 molecules by engineering yeast cells to produce 2-methyl-GPP (2me-...

Covalent Bonds of Carbon:A covalent bond is a type of chemical bond that forms typically between nonmetals. In a covalent bond, a pair of electrons are shared between two atoms. The number of electrons that each atom shares depends on the electron configuration of the atom and t...
Preferably the radical shouldt contain more than seven carbon atoms and those containing a still larger number of carbon atoms are preferred. Alicyelic guanamines can be prepared from fairly cheap raw materials and are obtainable in good yields, particularly when a strongly basic condensing agent ...
