Analysis of a Volatile Liquid Abstract: The purpose of this experiment was to use various methods of analysis to determine the identity of an unknown volatile liquid. In the first part of the experiment‚ the molecular mass was found by using water to find the volume of a flask through calculations and this as well as the mass of the gas of the unknown liquid were put into the a manipulated version of the ideal gas equation to determine the molar mass of the liquid‚ which was 14.21g per

solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found to be 117C

Project 5 Lab Assignment Lab 10.1 Using your results How did you score? (Include score) How high are your daily and weekly stress scores? The highest score daily is around 10 pm when I have to drive from one campus to the other to get to class in time and I have to deal with all the people driving. And my highest score weekly is usually Saturday and Sunday that are the days that I work the whole day. Are you satisfied with your stress rating? If not‚ set a specific goal. I am actually

SOLID STATE MARKS = 04 SOLID STATE A solid is that form of matter that possesses a definite shape and a definite volume. There are two types of solids: Crystalline solids: Solids with a definite geometric pattern and are anisotropic in nature. Examples: Iron‚ copper‚ silver‚ sulphur etc. are some elements which form crystalline solids. Potassium chloride‚ sodium nitrate etc are some of the compounds‚ which are crystalline

Impacts of solid waste on health The group at risk from the unscientific disposal of solid waste include – the population in areas where there is no proper waste disposal method‚ especially the pre-school children; waste workers; and workers in facilities producing toxic and infectious material. Other high-risk group include population living close to a waste dump and those‚ whose water supply has become contaminated either due to waste dumping or leakage from landfill sites.

* Cube In geometry‚ a cube is a three-dimensional solid object bounded by six square faces‚ facets or sides‚ with three meeting at each vertex. As the volume of a cube is the third power of its sides ‚ third powers are called cubes‚ by analogy with squares and second powers. A cube has the largest volume among cuboids (rectangular boxes) with a given surface area. Also‚ a cube has the largest volume among cuboids with the same total linear size (length+width+height). * Parts:
