- Air from a bag is pumped into a chamber and past a dark acclimated leaf (the leaf is in the dark and has been for a long time). Assume that the air in the bag has [CO2] of 350ppm and Relative humidity of 20%, make qualitative predictions about how the [CO2] relative humidity of the air after it leaves the chamber.Please explain the meanufacturing of Ethanol. Full process diagram with material balance as well as heat balance.Show all working explaining detailly each step. Imagine you were provided with: a stirrer, a thermometer, a plastic cup, a stand, a piece of plywood with holes in it, through which a thermometer and a stirrer can pass, a large measuring cylinder, some warm water, some cubes of ice, a clean rag. Measure the temperature (θR) of the room. Transfer a known volume (V1) of warm water into the cup that can fill it to about two thirds of its capacity. Keeping the cup open, stir the warm water continuously until its temperature falls down to a value θ1 that is about 5 or 60C above θR. Dry some small blocks of ice with a clean rag and drop them into the warm water. Place the wooden or cardboard lid over the cup, with the stirrer and the thermometer in the holes in it. Stir the water continuously and put just enough small blocks of ice in it to make its final steady temperature θ2 to be about 5 to 60C bleow θR . Pour all the water into a measuring cylinder and measure its volume V2 . Estimate…
- Though many MNCs espouse and follow rigid codes of social responsibility in their home countries they are often not as diligent with respect to ‘host’ or overseas countries. In 1984 the Bhopal disaster in Madhya Pradesh, India killed 3,787 and impacted a further 558,125 people. The corporation in question was Union Carbide, a majority USA owned company. Indian courts convicted the Chairman and other senior executives of “…causing death by negligence”. Why do you believe that Union Carbide had a less stringent policy in India with respect to negligence than they did in the USA?It is desired to determine the molecular weight of an organic compound known to be volatile. For this, a glass balloon with a full volume of 152 mL is weighed and the weighing result is recorded as 215 g. Then, the organic compound that is desired to have some molecular weight in liquid form is added into the balloon and evaporated in a water bath until dryness. After the steam temperature is measured as 90 °C, the balloon is left to cool and the organic compound in the balloon condenses again. The balloon is then weighed again and recorded as 215,367g. Find the molecular weight of this organic compound since the pressure of the environment where the experiment is performed is 700 mmHg.which is an active ingredient of a fumigant insecticide that turns directly from solid to toxic vapor xylene, anthracene, biphenyl, naphthalene

The minimum number of centrifuge tubes in a centrifuge machine during its operation is one. __________ 12. Never place reagents directly onto the weighing pan of a balance, always use weighing paper, a beaker, or some other container. __________ 13. To transfer a solution, the stirring rod touches the delivery point of the reagent vessel and the wall of the receiving vessel. __________ 14. An open flame is the heat source for heating or evaporating flammable liquids. __________ 15. Most chemicals used in experiments can be discarded into the sink.
- Air with a dry-bulb temperature of 38oC and a wet-bulb temperature of 27oC is scrubbed with water to remove dust. Water temperature is maintained at 25oC. The air leaving the scrubber is in equilibrium with water. It is then heated to 93oC in an air preheater and admitted to an adiabatic rotary drier. The air leaves the drier at 49oC. The material losses moisture at a rate of 0.05 kg of water per kg of product. The total product is 1000 kg/h. Determine the following (Use a psychrometric chart): a) Total weight of dry air used per hour. Answer: b) Total volume of air leaving the drier. Answer:Determine the stoichiometric amount of air required for combustion of an organic solid waste: The waste composition is C760 H1980 O875 N13 S Excess flow rate/hour if 500 tonnes/day waste (dry basis) Excess air requirement set at 175% per tone For efficiency, incinerator operates 24x7If to a solution of NaOH, in water and ethanol (20 ° C) 3 mmol of A (106.11 g / mol) and 2 mmol of B (58.06 g/ mol) and stirred magnetically for 10 minutes. After the reaction is completed, we proceed to isolate (work- up) and purify at C (246.29 g/ mol) yielding 0.300 g of the pure product.
