through a pipe at a rate of 175 m3/h. a) What is the mass flow rate of this stream in kg/min? b) What is the molar flow rate in mol/s? 5. A mixture of methanol and methyl acetate contains 15.0 wt% methanol. a) Determine the g-moles of methanol in 200.0kg of the mixture. b) The flow rate of methyl acetate in the mixture is to be 100.0 Ib-mole/h. What must the mixture flow rate be in Ibm/h 6. The feed to an ammonia synthesis reactor contains 25 mole% nitrogen and the balance hydrogen

Fischer Esterification – nucleophilic substitution reaction Strong acid catalyst (concentrated sulfuric acid Purpose of a reflux is to heat a reaction mixture at its boiling temperature to form products‚ without losing any of the compounds in the reaction flask TO HAVE GREAT PERCENT YIELD: As reaction is reversible‚ removal of water or the addition of an excess of one of the reactants (cheaper one) drives the reaction towards formation of ester. (Excess carboxylic acid is used) Adding excess

GAS CHROMATOGRAPHY EXPERIMENT The purpose of this experiment is for the student: 1) to learn the general theoretical aspects of gas chromatography as a separation method‚ 2) to learn how to operate gas chromatographs specific to COD‚ 3) to become familiar with using the gas chromatograph (GC) to qualitatively identify components of mixtures‚ 4) to be introduced to and to interpret the quantitative data available via gas chromatography‚ 5) to gain insight into how the GC technique is used

also remove residues from glass and porcelain and it can also remove super glue from the skin. Perhaps‚ acetone is very useful in our everyday lives. Acetone is also known to remove ball pen marks on fabrics and clothings. It has ethyl acetate that is said to remove ball pen stains. Most people accidentally rubs ball pen marks on their clothing on a daily basis. The study was done to find out if acetone is more effective and easier to remove ball pen marks on clothings or fabrics

component of vinegar (apart from water; vinegar is roughly 8% acetic acid by volume)‚ and has a distinctive sour taste and pungent smell. Besides its production as household vinegar‚ it is mainly produced as a precursor to polyvinylacetate and cellulose acetate. Although it is classified as a weak acid‚ concentrated acetic acid is corrosive‚ and attacks the skin with the chemical formula CH3CO2H (also written as CH3COOH or C2H4O2). It is a colourless liquid that when undiluted is also called glacial acetic

conditions. This is achieved as a result of the consecutive biochemical breakdown of polymers to methane and carbon dioxide in an environment in which a variety of microorganisms which include fermentative microbes (acidogens); hydrogen-producing‚ acetate-forming microbes (acetogens); and methane-producing microbes (methanogens) harmoniously grow and produce reduced end-products. Anaerobes play important roles in establishing a stable environment at various stages of methane fermentation. Methane
