You could go days without food and hours without water‚ but you would last only a few minutes without air. On average‚ each of us breathes over 2‚000 gallons of air each day. You must have air to live. However‚ did you know that breathing polluted air can make you sick (EPA) environment protection agency? Although we need our factories to produce our products and transportation to get place to place air pollution has a great deal on our industrialization that leads to many hazardous effects. An

replaced. Deforestation is especially present in the tropical areas because of the poor economic conditions of the countries where big rainforests are located. The deforestation will affect the change of the global climate‚ the agriculture and water supply. Water scarcity will cause food scarcity‚ and all this will lead to high food prices‚ thus causing economic and political instability‚ especially in the developing countries. In order to have a sustainable development‚ we will have to replace our

gas phase and liquid phase. In industries‚ many companies have high demand on both quality and quantity of water for production. Membrane process can be used to separate chemical substances in various types and sizes from microscopic to molecular level. The objective of this experiment is to study the characteristic of four different types of membrane. The membranes used in this experiment are polyamide film ( AFC 99 ) as membrane one ‚ polyamide film ( AFC 40 ) as membrane two ‚ cellulose acetate

11 Nov 20014 Air pollution effect on humans There’s nothing quite like opening the door and breathing fresh‚ clean‚ air—but how clean is the air you’re breathing right now? Unless you’re a scientist with a chemistry lab at your fingertips‚ there’s no real way of knowing. The gases you’re sucking up through your nose could be slowly killing you: according to the World Health Organization‚ around two million people die prematurely from the effects of polluted air every single year. Air pollution has

Air pollution is a major problem facing our environment today. This dilemma is harmful to every single living creature on this planet. How can we limit the causes of air pollution? There are industrial as well as residential causes of air pollution. How can we limit the effects of air pollution? We all know it affects the environment‚ but it also can affect us directly. Air pollution can be defined as impureness of the air. Air pollution is all around us. It might not be as clearly visible in

Biotechnology‚ Mapua Institute of Technology ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers for mixing

HEAT EFFECTS AND CALORIMETRY Experiment No. 2 I. RESULTS A. Determination of Heat Capacity In this experiment‚ an improvised calorimeter was used to determine the heat capacity. The calorimeter weighed 4.47 grams prior to the addition of water. Tap water‚ 40 mL to be exact‚ was added to the calorimeter which increased the weight to 43.87 grams. The water was measured using a thermometer thrice (at room temperature‚ boiling‚ and addition of boiling water to room temperature water). The first
