Abstract Unknown white compound (823U) was discovered in the lab. In order to dispose of it correctly, the substance and its physical and chemical properties had to be identified. The unknown white compound was one of a list of 15 compounds. 5g of the unknown compound were given in order to correctly identify and discover its physical and chemical properties. In order to do so, a solubility test, a flame test, and ion tests were conducted. From the results of these initial tests and the given list

Chemical Name and CAS Registry Number: 1- Ethenyl -2- pyrrolidinone homopolymer [9003-39-8] Empirical Formula and Molecular Weight: (C6H9NO)n 2500–3 000 000 The USP 28 describes povidone as a synthetic polymer consist of linear 1- vinyl-2-pyrrolidinone groups, polymers of various molecular weights

Introduction In many pharmaceutical industries, spray drying is used to create particles that are utilized to form many oral or inhaled drugs. Thus, these particles are designed to be pressed into tablets or dispersed in aerosols. A spray dryer is a processing unit that produces a mist where the solvent is quickly evaporated, leaving particles that are collected in a cyclone. This quick evaporation leaves the molecules fixed in their current positions, preventing the molecules from finding their

Grouping elements with similar chemical properties together Date: 4.10.2012 Objectives The objective of this experiment is to experimentally investigate which elements show similar chemical properties. Chemical principle Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a dull gray, silver solid under standard conditions. Calcium atoms have an electron configuration of (2, 8, 8, 2) and 2 outermost shell electrons. Calcium is in group 2 and period 4 of the

both chemical and physical properties. A chemical property is determined by the substance's ability to react with other substances. Chemical properties react to air, rust, tarnish, rot, burning, and etc. According to Modern Chemistry, a chemical change is a change that occurs that causes the identity of a substance to change; something new is formed. A chemical change is irreversible, meaning that it can’t change back to it’s original state. According to Modern Chemistry, a physical property is description

Acetanilide was purified via recrystallization and its purity was checked using its melting range and thin layer chromatography. Our results yielded a very pure product. Introduction: This molecule is primarily noted for its antipyretic and analgesic properties because the human body metabolizes it mostly to paracetamol. However, due to its high toxicity it is no longer administered as a drug on its own, it is mainly used in the synthesis and manufacture of other drugs. Hazards include: acute oral toxicity

- Environmental factors: The measured physical and chemical properties of the water in El-Mansouriya stream during the study period that presented in table (1), showed clearly that almost all parameters elevated in winter and lowered in summer, except for temperature (Temp.) and biological oxygen demand (B.O.D) recorded their maximum values during summer (29.20C-2.4 mg/L), while the minimum were during winter (17.20C-1.0 mg/L), respectively. Moreover, the measures clarified a narrow variations among

cm−1 for T-BN and F-BN, respectively. The larger FWHM value and higher wavelength demonstrated a low crystalline structure along with the low interlayer interactions at T-BN as compared to that of F-BN [32–34]. The intermolecular bonding and chemical properties of the as-synthesized BN were characterized by FTIR spectroscopy (Figure 4c). The FTIR analysis of T-BN shows two strong absorption peaks at ∼1382 and ∼790 cm−1, ascribed to the in-plane B–N transverse stretching vibration and the B–N–B out-of-plane

Ultrasonic is the universally accepted technique to study the physico-chemical properties of the liquids, liquid mixtures, electrolytic solutions and polymeric solutions. Liquids, liquid-mixtures and solutions find wide applications in medical, pharmaceutical, chemical, lather, textile, nuclear and solvent, solution related industries. The study and understanding of the thermodynamic properties of liquid mixtures and solutions are more essential for their applications in these industries. The measurements
