Chemistry Project on Evaporation of Liquid Acknowledgement I would like to show my gratitude to my Chemistry Teachers Ms Seema More without whose support and encouragement this project could never have have taken the present shape . I would also like to thank my lab incharge Mr. Kakde For helping Me out During The Practical Part Of This Project. Aim Acknowledgment I am are greatly thankful for the cooperation and help from the Community Science Center (CSC) authorities and the Chemistry lab

Everything has some kind of reaction going on in our living area. It is just we do not get to see or realize that where n how we having our life much easier than it used to be. In these writing assignments‚ the topic is about the organic chemistry. In organic chemistry‚ we all have different kinds of compounds

What sort of thing form in chemical reactions? Products are the finished product of a chemical equation‚ and reactants are what make up the products. ( atoms‚ matter‚ molecules‚ energy‚ rate‚ temperature) Name some compounds: H2O (Hydrogen and Oxygen elements - Water) CH4 (Carbon and Hydrogen elements - Methane) NaCl (Sodium Chloride- salt) Different types of compounds: Metal + Metal = Metallic Compound Metal + Non-Metal = Ionic compound Non-Metal + Non-Metal = Covalent compound Different types

Safety measures in the chemistry laboratory The mentors are responsible for instructing the competitors as to the risks to which they are subjected when working in a chemistry laboratory‚ as well as to the basic safety measures‚ and first aid. Specific behavioral and safety measures must be obeyed to prevent accidents. Rules in the lab: * Use protective clothing all the time (e.g. lab coat and safety glasses) * Use a hair band to keep your hair away from your face. *

Procedure. 1) Accurately weigh approximately 2 g of the mix and dissolve it in 50 mL of diethyl ether. Be sure to dissolve the entire mix since it is not homogeneous. 2) Pour the solution into a separatory funnel. 3) To extract the nicotinamide from the mixture‚ add 5 mL of 5% HCl and shake gently. Draw off the lower aqueous layer into 125 mL Erlenmeyer flask and repeat the extraction with a second portion of HCl. Combine the three extracts and then set this mixture aside. 4) To separate the

Chemistry is a central discipline and a very important subject which is very often studied thoroughly in most colleges and universities. Like physics‚ math‚ economics‚ biology‚ or geometry‚ chemistry for many centuries remains a root science for the development of a great deal other theoretical and practical scientific branches and disciplines. Very often‚ chemistry becomes a topic of academic essays‚ term papers‚ research papers‚ reviews‚ and other academic papers. Writing a research paper on

The Role Of Chemistry To Our Society Chemistry plays a huge and important role in society‚ with relation to shelter and clothing. For example‚ chemists come up with new paints and epoxy sprays that protect shelters from the wear and tear inflicted by rain‚ wind‚ sun and pollution. These space age coatings and paints are designed to make properties look better‚ perform better and last longer. Thermal chemical compounds may protect rooftops and also help structures stay at the right temperature

directly affects safety and protection measures for hazardous chemicals. These two types of analyses are collectively known as analytical chemistry and a basic understanding of it is important for any professional handling and dealing with chemicals. Objective: The objective of this lab is to introduce the participating students to qualitative analytical chemistry. The group will be given an unknown pure organic liquid sample and will need to perform a series of tests in order to identify the species
