Air Quality Essay – paragraph 2 and 3(body) By Edwin Lin‚ The air quality is deteriorated by humans heavily using fossil fuels to power up automobiles‚ generate electricity‚ and used for many other purposes. Unfortunately‚ fossil fuels are nonrenewable resources‚ and the burning of the fossil fuels releases the pollutants into the air‚ and forms a mixture of fumes with the air. It is called smog. Smog can block the radiant beams of energy from the Sun from entering and exiting the Earth’s atmosphere

VARIOUS LAB TEST ON CEMENT: Checking of materials is an essential part of civil engineering as the life of structure is dependent on the quality of material used. Following are the tests to be conducted to judge the quality of cement. 1. Fineness 2. Soundness 3. Consistency 4. Initial and Final Setting Time of Cement FINENESS OF CEMENT: We need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement

Water Analysis Lab Report Purpose: In this lab we will be testing a number of water samples. These water samples come from various water sources. Each of these water samples will undergo four different tests. The four tests include a pH test‚ a conductivity test‚ a total and phenolphthalein and alkalinity test‚ and a total hardness test. This lab requires comprehension of lab material and techniques learned in prior labs (Kippenhan‚ 2012). Procedure: Each

UNKNOWN SAMPLE #97 COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS DR. BUDRUK CHM 152 LL SEAN MARKIS 4 FEBRUARY 2015 Introduction Using a Lewis base neutral molecule to donate electron pairs (ligands) to a Lewis acid metal ion center to form a single cluster (complex) ion. When the complex ions forms with a metal ion (chelation) the ligand used is called the (chelating agent). EDTA acts as a great chelating agent due to the Nitrogen and Oxygen donating an electron pair to the

Cross contamination is a process by which bacteria or other microorganisms are unintentionally transferred from one substance or object to another‚ with harmful effect. What that means for example‚ if you get sick from eating at a restaurant that might mean that the food handlers are not following correct food safety guidelines. Some examples are the some of the food handlers wash their hands or people forget to not touch there face and hair. But it gets worse there are also some people that forget

an initial height of 4 feet at an initial velocity of 350 feet per second. The gravitational force of Earth is pulling the rocket down at a rate of 16 feet per second per second. The formula for‚ s(t)‚ for the function that models the height of the water balloon at time t‚ in seconds‚ is s(t)= -16t2 + 350t + 4. We can determine how long it takes for the rocket to land from the graph where the function intercepts the x-axis because this is the value where the height of the rocket is 0 feet. From the
