Introduction Mass spectrometry is a type of analytical technique that is used to ionize chemical compounds into charged molecules and they are separated based on the mass-to-charge ratios and their kinetic energy. It is thus can be used to identify the presence of the compound, their masses as well as their quantities. During the ionisation process, sample molecules are bombarded with a beam of electrons, electrons may be captured by the molecules to produce radical anion or it may lead to displacement

2.6.4 Vacuum drying Amellal and Benamara (2008) investigated the drying ability of date (Phoenix dactylifera L.) pulp cubes from three Algerian common varieties (Mech - Degla, Degla - Beida, and Frezza). Drying process was carried out under partial vacuum (200 mbar) at 60, 80, and 100° C. Compared to the Newton model, the Henderson and Pabis model better described drying kinetic of Mech - Degla and Frezza pulps at 60 and 80° C with a mean relative error (MRE) not higher than 6.07%. The same model

Ultimately, the data somewhat supported the hypothesis because it was justified as the amount of hydrogen peroxide (mL) increases, then the displaced volume of oxygen (mL) that is produced will increase and eventually level out. This is because the hydrogen peroxide is substrate specific to catalase which is found in the liver solution tab. The two products react to create an active site which produces water and oxygen. Therefore, as the amount of hydrogen peroxide increased then the displaced oxygen

1. Why did magnesium react with zinc nitrate and why can’t lead react with zinc nitrate? The reason why magnesium reacted with zinc nitrate is because magnesium is two elements higher than zinc on the activity series. When a metal is higher than another on the series, it means it is capable of replacing whichever metal is beneath it in a single displacement reaction. The distance between the two metals has a correlation with the slow execution of the reaction as the closer the elements are on the
