Question: What is the COD equivalent of methanol (CH3OH), given the reaction shown below? Express your answer in gram O2 per gram CH3OH and round to the nearest 0.01 .2CH3OH+3O2→2CO2+4H2O OH),given the reaction shown below?...
What amount of heat, in kJ, would be involved in condensing 15.8 g of CH3OH? (delta H vap = 38.0 kJ/mol) Determine which requires more energy transfer. Specific heat of water is 4.184 J \cdot g^{-1} \cdot C^{-1} and specific heat of aluminium is 0.900 J \cdot g^{-1} \cdo...
非线性规划是具有非线性（ ）的数学规划，是运筹学的一个重要分支。非线性规划是20世纪50年代才开始形成的一门新兴学科。70年代又得到进一步的发展。非线性规划在工程、管理、经济、科研、军事等方面都有广泛的应用，为最优设计提供了有力的工具。
In this process, the fat or oil is first purified and then reacted with an alcohol, usually methanol (CH3OH) or ethanol (CH3CH2OH) in the presence of a catalyst such as potassium hydroxide (KOH) or sodium hydroxide (NaOH). When this happens, the triacylglycerol is transformed to form este...
What is a copolymer?Polymer Chemistry:The branch of chemistry that deals with polymers' structure, synthesis, chemical reactions, and properties is called polymer chemistry. Polymers have broad applications in our daily life. Most of the materials around are one form of polymer. An example is a ...
How many moles are in 75.70 grams of CH3OH? How many moles are in 120 grams of CH3OH? What would be the mass in grams of 1.505 x 10^{23} molecules of carbon disulfide? If the molar mass of a substance is 34.1 g/mol, what is the mass of 3.01 10 24 molecules of the sub...
aThe best joke in Scoop is about the newspaper’s owner, Lord Copper. The editors can never disagree with him. When he’s right about something they answer “definitely”, and when he’s wrong they say “up to a point, Lord Copper.” It seems reasonable to suppose that, in the real...
