new technologies in ethanol production

%. If air enters the fermentation mixture, ethanol gets oxidised to ethanoic acid which in turns makes it sour. Distillation of a solution of ethanol and water produces an azeotrope, containing 95% ethanol and 5% water. Pure ethanol is obtained by membrane ..

Solubility Product - Compounds such as AgCl, AgBr, AgI, BaSO 4 etc., when placed in a polar solvent such as water, dissolve to a very limited extent to produce ions in the solution. These sparingly soluble ionic substances (salts) establish an equilibrium between the solid phase and the i..

Primary and Secondary Productivity - 'The amount of organic matter or biomass produced by an individual organism, population, community or ecosystem during a given period of time is called productivity'. Primary production refers to all or any part of the energy fixed ..

Dot Product of Vectors and the Resolution of a Vector - It was mentioned earlier that, displacement vectors are added to displacement vectors, or velocity vectors are added to velocity vectors. Just as it is meaningless to add scalar quantities of different kinds, such as mass and tempera..

The food agency inspected a sample of 500 pastries from a bakery and found that 15 were spoiled. After improving the quality of production, the agency inspected a new sample of 900 pastries from the bakery and found that 20 were spoiled. What is the probability of spoiled pastri..

The food agency inspected a sample of 1500 pastries from a bakery and found that 20 were spoiled. After improving the quality of production, the agency inspected a new sample of 2900 pastries from the bakery and found that 25 were spoiled. What is the probability of spoiled past..
