Chemical process

is the “ability for a given substance, the solute, to dissolve in a solvent” . The effect of temperature on solubility is that when heat (energy) is added, it increases the speed on which molecules and particles move, therefore making it a quicker process. Where as with cooler temperatures there aren’t as many particles because the solvent doesn’t contain as much energy as warmer temperatures, therefore not dissolving as well as it could if it was warmer. To make jelly you first of all need to…

and cadmium and minimize the use of zinc and nickel. Also, it is used in immersion deposition for all surface replaceable ions to become tin. However, to attain good results, a good base metal preparation is needed. It is an environment-acceptable process and has a low cost. In electrodeposition, it is used as an alternative for tin-lead and cadmium coatings due to its good solderability and corrosion resistance. But, formation of thin whiskers can also be observed. It can also be used in hot…

Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment…

reason concerns the pumping process. State 1 is a mixture of liquid and vapor. Great difficulties are encountered in building a pump that will handle the mixture of liquid and vapor at 1 and deliver saturated liquid at 2. It is much easier to condense the vapor completely and handle only liquid in the pump: The Rankine cycle is based on this fact. The second reason concerns superheating the vapor. In the Rankine cycle the vapor is superheated at constant pressure, process 3–3. In the Carnot…

Paragraph 1 Iron phosphate structure with a symbol of FePo4, has crystal structures of FeO4 and PO4 as its tetrahedral links. There would be changes of this quartz type that can be determined by the neutron poly difraction between 294K and 1073K, according to Z. Kristallogr. While structural parameters of the iron phosphate depends on the temperature, whereby iron phosphate would be a beta-phase from an alpha-phase when temperature increases from low to high. Irregularity would also be…

Atoms are made up of three parts: protons (positively charged), neutrons (uncharged) and electrons (negatively charged). For example: Sodium ( ) has 11 protons, 12 neutrons and 11 electrons. 2. Molecule: Molecules form when two or more atoms form chemical bonds with each other. It doesn’t matter if the atoms are the same or are different from each other. For example: 3. Isotopes:…

Phase 2 – Agarose Gel Electrophoresis 1. Obtain our four H, E, L, and P labeled micro tubes and place them on ice. 2. Set the micro pipet to 2.0 ul. 3. Transfer 2.0 ul blue dye to each of the four H, E, L, and P micro tubes. 4. Mix the four micro tubes by using this two-step method: * Place each tube briefly on the vortex to get the components to collect at the bottom of the micro tubes * Pulse spin the four micro tubes in the centrifuge to mix all of the components completely. 5.…

1.4 Effect of Microcrystalline Cellulose (MCC)Type Formula F12 was utilized to study the effect of changing the type of MCC(Avecil PH-101 ) as a carrier material instead of (Avecil PH-102) in F8 on the dissolution behavior of the prepared Zolmitriptan liquisolid ODTs. Although the DT of formula F12 (79 sec.) was greater than F8 (48 sec.) as in Table(18),the dissolution behavior of the formula F12 was faster than F8 as in Table (18) and Figure (48), this difference was non…

They are responsible for physical properties of compounds such as crystal structures, melting points, boiling points, vaporization, viscosity and surface tension, but not the chemical behavior of the three states of matter; when a molecular substance changes states, the atoms within the molecule are unchanged. These properties can therefore be used in identifying an unknown sample by comparing for example its observed melting…

“An asymmetric synthesis may be defined as a synthesis in which an achiral unit is an ensemble of substrate molecules is converted to a chiral unit such that the possible stereoisomers are formed in unequal amounts.” It relates to any synthetic process that incorporates one or more new elements of chirality during a functional group transformation. Asymmetric synthesis involves the formation of chiral molecules. An object is said to be chiral, if it cannot be superimposed upon its mirror image…
