Non-renewable sources of ethanol include the hydration of petroleum derived ethylene
(H-C=C-H) + H-O-H -> H4C2OH
A can is nonrenewable because it is made of metal and metal is a nonrenewable resource. But it can be recycled. It doesn't necessarily mean it is renewable. The simple answer is that a can is nonrenewable.
One simple way is to measure the specific gravity of the ethanol using a hydrometer. Another method is to use a simple alcoholmeter to measure the alcohol content. You can also use a refractometer to measure the refractive index of the ethanol, which can indicate its purity.
Ethanol burns differently than a mix of ethanol and water because water has a higher boiling point compared to ethanol. Water will absorb heat during combustion, which can lower the overall temperature and affect the efficiency of the burning process. This can lead to a slower and less complete combustion compared to pure ethanol.
Yes, ethanol combustion is an exothermic process. When ethanol reacts with oxygen during combustion, it releases energy in the form of heat and light, making it an exothermic reaction.
95% ethanol is commonly used in laboratories because it is an effective solvent for a wide range of chemicals and biological substances. It also has antimicrobial properties, making it useful for disinfecting surfaces and equipment. Additionally, 95% ethanol is less prone to evaporation compared to absolute ethanol, providing a more stable solution for various applications.
it is renewable because you can grow more corn
Depends. What do you mean with "treated with ethanol"? In bread making, ethanol (or ethyl alcohol) are produced without the intention of making wine. so it's halal.
The pH level of ethanol is around 7, making it neutral.
the advantage of making ethanol by fermentation is the raw material is a renewable resource.the disadvantage is that it takes too long.
I don't live in Iowa, but I have been there to visit family. A renewable one would be corn (for ethanol) and soy, and nonrenewable would be coal. But for nonrenewable resources not produced in Iowa, but used there, there's oil and natural gas.

technical grade is bethween 96% and 98% ethanol and ethanol absolute means pure ethanol whithout water ('almost') 99.9% ethanol Absolute ethanol has no water whereas 96% ethanol has 4% water or 98% has 2% water. Thus, the reaction can occur with water.
Ethanol is used for brewing, making solvents, drugs, preparation of various compounds etc...
Divide the mass of the ethanol by the sum of the mass of the ethanol + that of the water and multiply by 100. Mass ethanol/(Mass ethanol + mass H2O) (x100)
Not sure.
Ethanol is more polar. Propanol has three ch3-OH groups which affect the polarity, making it less polar.
The only way to tell whether ethanol is present in gasoline is to look at the gasoline pump. If it contains ethanol, there should be a large sticker on it stating what percentage of ethanol is in the gasoline.
