raised by the auction. Everyone has his right to consume air or use air or whatever you would like to do with air. It is part of the environment and thus‚ a free resource. The EPA auctions or the allowances aim to reduce the emissions of sulphur dioxide. And firms are allowed to buy and sell these allowances to other firms when left unused. I believe that this doesn’t affect the people’s rights to the air. The environment is a priceless resource. Since then‚ people have been witnesses of the

DESIGN OF AN ABSORBER Problem statement To design an absorber (packed tower) for the absorption of 785.15 kg/h of sodium metabisulphite (Na2S2O5) at an average temperature of 68˚C and Y atm pressure with sulphur dioxide gas counter-currently reacting with Na2SO3 rich feed. Introduction Absorbers are vertical towers used in distillation‚ gas absorption and liquid-liquid extraction processes. Absorbers can be operated co-currently or counter currently. In the former‚ both fluids involved are fed

Practical 3 Title: Effect of dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer

manufactured in industry though contact process 2. The process contain three stage STAGE1: Production Of Sulphur Dioxide From Sulphur i. Combustion of sulphur or sulphide ores in the air produce sulphur dioxide SO2. S(s)+O2(g)(SO2(g) sulphur ii. sulphur dioxide is dried and purified. STAGE2: Production Of Sulphur Trioxide From Sulphur Dioxide i. The purified sulphur dioxide SO2 and excess air are passed over vanadium(V) oxide V2O5 at controlled optimum condition optimum condition

Since we know the shape of the molecule and the bond polarities are not identical‚ the molecule is polar (or has a net dipole moment). Let’s look at the Lewis structure in the SO3 molecule. In SO3 sulfur has 3 double bonds with oxygen. Sulfur also has no lone pairs. Since there are 3 effective pairs of electron density‚ it takes sp2 hybridization. There are no lone pairs so it takes a trigonal planar shape. The bonds are identical and symmetrical. This results in a molecule

The Environmental Impact of Carbon Dioxide (CO2) Carbon Dioxide (CO2)‚ a chemical made up of one carbon atom and two oxygen atoms‚ is a non-flammable‚ odorless and colorless gas that exists naturally in the atmosphere. CO2 is one of the greenhouse gases‚ amongst methane‚ nitrous oxide and other gases‚ which keeps the Earth’s temperature habitable (UCAR). Without it‚ the Earth will be inhospitably cold. However‚ ever since the mid-nineteenths century‚ humans have significantly increased the amount

Adding to that‚ an important component in photosynthesis is carbon dioxide‚ without carbon dioxide‚ photosynthesis can’t occur. If we were to perform photosynthesis‚ from where are going to get

Durga Puja is one of the auspicious occasion celebrated with great enthusiasm across India. In modern times‚ festivals are getting commercialized and taking the shape of pomp and show. Different communities set huge gigantic and attractive bright idols in order to compete with other communities. This all leads to major problem of environment pollution. Idols made by non biodegradable material and toxic paints contaminate water making it unfit for survival of aquatic life and drinking purposes.

Deforestation The “Slashing and burning” of rainforests has to stop. The deforestation of our rainforests is effecting our environment and us more than you may think. We get the oxygen we need from trees‚ forests protect us from Carbon Dioxide‚ and forests protect most of Earth’s plants and animals. We need trees to breathe and rainforests to protect us from harsh things that we emit from our bodies. Many rainforests help and protect us. “More than 20% of the world’s oxygen comes from the Amazon”
