I need help with the writing a paragraph of ``OBSERVATIONS`` part of the Lab report. It is a substituition and Elimination exp. Please see exp.details below: We started with 2.1 g of solid. Final mass after crystalization was 1.1g. Melting point of the product was 36.4 C. Therefore 2-napthyethyl ether formed based on BP. The product formed colorless crystalline solid. Procdure: a solution of 1g of 2-naphtol was mixed with 4.0mL of 30% aqeous potassium hydroxide and 25 mL of...

hello, i need help with the questions in the second photo
Experiment 6. the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents....

Argumentation and Documentation Classify each substance as metallic, ionic, molecular or covalent network based on your experimental results and further observations Part I. Testing Conductivity of Substances at Room Temperature Two substances were electrically conducting solids. The only classifications for substances that conduct electricity as solids are metallic or covalent network solids. Use the malleability property of metals to determine the classification of the two substances. Part II. Testing Conductivity of Solutions...

Hello, I need help solving the 3 parts of this question.
Part - Factors affecting the dissolution process The rate at which a solute dissolves in a solvent depends on the kinetic energy of the soluton, theme of contact and the surface area of contact between the solute and the solvent particles. Both endothermic and exothermic dissolution processes will respond similarly to each factor, however the charge may be more pronounced depending on the thermodynamic penters of the reaction. As...

Need help on providing reactions that describe the acid-base
extraction and neutralization processes used in this experiment.
Provide a statement of solubility of each starting material and
product.
The experiment to be performed this week involves liquid-liquid extraction using a separatory funnel. Read chapter 15 in Zubrick to familiarize yourself with the use of the glassware for extraction and washing. Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substances that have varying solubility...
