The molecular ion represents the entire molecule in question, prior to any fragmentation. Each analyte molecule is given a charge of one, so the molecular ion m/z value represents the molecules total mass. Ionization, specifically electron impact (EI) ionization, is used to remove an electron f...
To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in...
Capping-layer precursors consist of 15 A-site organic cations in different lengths and shapes (Fig. 2a). The number of carbon atoms in these materials ranges between 1 and 16, with primary (two N–H bonds), secondary (one N–H bond), tertiary (no N–H bond) amine, or quaternary (no...
In pharmacy, the isomerism shown by the structure provides a way to distinguish the two drugs. For instance, the effect of dextroamphetamine and amphetamine in the body of a human is different. Answer and Explanation: Given molecule is Bromo-toluene Bromo-toluene is a mo...
Binders are fantastic tools for detoxification and are often recommended by functional medicine practitioners like myself. There are a number of different binders that you can turn to. They all offer different benefits and different levels of effectiveness. ...
Boiling points increase as the number of carbons is increased.Branching decreases boiling point. What effect does branching of alkane have on boiling point? As branches increases, the surface area of molecule decreases resulting in a small area of contact. As a result, the Van der Waals force ...
How many carbons from glucose enter the metabolic pathway of the Krebs cycle? a. one b. two c. three d. four e. six The two molecules of pyruvate are completely degraded in the Krebs cycle to form how many molecules of ATP, NADH2, and FADH2 respectively? a) 3,4,5 b) 5...
The number of peaks represents the number of unique hydrogens attached to adjacent carbons. Look at that HUGE single peak at 1, that means that there is a carbon with only ONE hydrogen attached to it, which then means that in order to make up the other 3 bonds, there HAS to be a tr...
