How do you calculate the mass of carbon atoms in CO2?
You use the relative atomic mass of the atoms.Carbon has a relative atomic atomic mass of 12. Oxygen has a relative atomic mass of 16, so two of them is 32.Hence in whichever mass CO₂ you choose, there will be (12 ÷ (12 + 32)) × 100% = 27.3% to 3sf.
Which oils gives acid value and why?
Oils/fats are triglycerides.Many undergo limited hydrolysis [enzymatically/nonenzymatically] to the fatty acids [and glycerol].It is the fatty acid content which defines acid value of fats/oils.Oil refining process removes most of these liberated free fatty acids.Different oils have different acid values as they are hydrolysed under pocessing/storage conditions to a different extent.Range of expected acid values of most of the common fats/oils are available in the literature.Acid value of a given sample can also be determined by titrations against a base.
How is the concentration of hydronium ion affected when the acid is diluted?
The concentration of hydronium ions decreases when an acid is diluted because on adding water the H+ ions of the acid and hydroxyl ions of water react to form water molecules and the concentration of hydronium ions decreases.H+ + H2O →H3O+H+ + OH- →H2O
I need a quick middle school level science project on life science. Help please!!!! This is urgent.?
OK, how about looking at how different fertilizers affect pea seedling growth? It's interesting, cheap and quick.
Does the amount of water in which the acetic acid is dissolved affect the outcome of titration?
For the topic title: The only thing the amount of water would effect would be how much acetic acid you would need. A better way to think of a titration is that you are mixing two types of moles. If you have 10 mL of 2M or 10 mL of 0.2 M, the 0.2 M will take a lower volume to titrate because there are less moles to react. If you titrate the higher concentration a higher volume will be required. So you could have an extremely diluted acetic acid solution and the only thing that will change is the volume of stuff your titrating to react. The reason the sides are washed down during a titration is because as you're titrating it's possible that drops of titrant (stuff in the buret) will get stuck on the sides. Say you're buret reads 30 mL but 0.1 mL did not get into the beaker and it's stuck on the sides. That will mess with your results. We can rinse it as much as we want because that will never ever change the number of moles in the whole erlenmeyer, it'll just ensure everything you say is in there is actually in there.
I want to start a small scale rice bran oil refinery in India.What is the cost of setting up such a plant?
The setup of rice bran oil refinery plant involves some factors. These factors are determinant of the final cost. These factors includes factory area, equipment selections, capacity, raw materials and more.Most people concerns a lot of the equipment since it takes up a large part of the whole investment cost and it can decide the quality of final production, further have impact on the sales and profits. Then we will talk a lot about the rice bran oil refinery equipment and its cost.Based the input-output ratio, the BEST oil refining method for small scale rice bran oil refinery is batch type oil refining.What is Batch Oil Refining?Batch oil refining is designed for 1 ~ 20 tons per day crude oil refinery. It is suitable for various crude vegetable oils and animal oil, including rice bran oil, mustard oil, soybean oil, peanut oil, rapeseed oil, cottonseed oil, seal oil, fish oil and more. The main processes of batch oil refining is degumming, deacidification, decolorization and deodorizing. It is convenient in operation and simple in technical process.What is Rice Bran Oil and Rice Bran Oil Refinery Process?Rice bran oil is a kind of vegetable oil that obtained by extracting or leaching the rice bran. In addition to using as cooking oil, rice bran oil is used for making feed, soap, hardening oil, glycerin, stearic acid, oleic acid, paint resin and other industrial raw materials. The refining process for rice bran oil include Degumming, Neutralizing, Decolorization and Deodorization section.Small Scale Rice Bran Oil Refinery Plant – 1~10TPDIt can also be used to refine other kinds of vegetable oils.The quality of final refined oil can be guaranteedIt is easy to operate and the running cost is relative lowEquipment of 1TPD Small Rice Bran Oil Refinery PlantHeat Conduction furnace: 1 set Offer enough thermo for the refining sectionsSteam Generator: 1 set Produce steam for the workshopRefining Pot: 2sets Remove the gum, phosphoric acid etc.Decolorizing Pot: 1set Remove the color from neutralized oilDeodorizing Pot: 1 set Remove the solvent, smell, water from decolorized oilOther Auxiliary Equipment: Hot water Tank, Bleaching earth Tank, Air compressor, pumps, filters, Valves and more.E-mail: info@bestoilpressmachines.comWebsite: BEST Screw Oil Press Machine Expeller for Vegetable Oil Production
5 microlitre of oil is dissolved in 1 ml of toluene and 0.2 microlitres of this solution are injected on TLC plate. How can I calculate the amount of oil in microgram?
5 uL of oil in 1000 uL Toluene = 0.005 uL oil/uL Toluene0.2 ul of toluene solution = 0.2 uL * 0.005 uL oil/uL Toluene = 0.001 uL oil
