英语化学求分子式和试验试!A compound contains only carbon,hydrogen,and oxygen.Combustion of 10.68 mg of the compound yields 16.01 mg CO2 and 4.37 mg H2O.The molar mass of the compound is 176.1 g/mol.What are the empirical and molecular for
A silver vanadate compound was developed to be used in a permanent combustion tube packing for carbon-hydrogen analyzers. The material demonstrates increased activity and greater capacity for containing sulfur and the halogens. Silver vanadate also acts as an indicator for signaling its depletion. Anal...
A technological development is described through which the stable carbon-, oxygen-, and nonexchangeable hydrogen-isotopic ratios (delta C-13, delta O-18, delta H-2) are determined on a single carbohydrate (cellulose) sample with precision equivalent to conventional techniques (delta C-13 0.15 par...
Hydrogenolysis of the lignin model compound 4-propylguaiacol was studied on a sulfided CoO-MoO/y- A12O3 hydrotreating catalyst in a trickle-bed reactor at 473-673 K, 2.5-10.0 MPa, and LHSV 0.25-2.00 h"1. Experiments were carried out with neat 4-propylguaiacol feed under hydrogen pressure...
Compound-specific isotopic analysis of multiple elements (C, Cl, H) was tested to better assess the effect of a zero-valent iron-permeable reactive barrier... Carme,Audí-Miró,Stefan,... - 《Journal of Hazardous Materials》 被引量: 7发表: 2015年 Compound-Specific Carbon and Hydrogen Isotope...
the ratio of the number of hydrogen atoms to the number of carbon atoms; AImod, modified aromaticity index; DBE, the double bond equivalence; NOSC, the nominal oxidation state of carbon; Uns./Ali., the ratio of highly unsaturated and phenolic compounds to aliphatic compounds; Pol./Ali., ...
A carbohydrate is a molecule composed of carbon, hydrogen, and oxygen; in most carbohydrates, hydrogen and oxygen are found in the same two-to-one relative proportions they have in water. In fact, the chemical formula for a “generic” molecule of carbohydrate is (CH2O)n....
