What else can I help you with?
What is the percent volume of 25 mL of methanol in 75 mL of water?
25%
What is the volume and mass of alcohol?
The answers will depend on whether you mean a drop of alcohol or a bottle or a vat. Furthermore, it will depend on the type of alcohol: methanol, ethanol, propanol, etc.
Which substance would most behave as an ideal gas at stp choose one answer a n2 b h2o c ch3oh d hf?
i think its a and may be c bcz both are non polar and has weak forces of attraction . bt nitrogen has low mass as compared to methanol so may be nitrogen is the right answer.
What is the mole fraction of methanol in a solution that contains 6.0 mol of methanol and 3.0 mol of water?
The total moles of solute and solvent in the solution is 9.0 mol. The mole fraction of methanol would be the moles of methanol divided by the total moles. Therefore, the mole fraction of methanol in the solution is 6.0 mol / 9.0 mol = 0.67.
What is the mole fraction of glycerol in a solution which contain 90g of water and 6.4g of methanol and 18.4g of glycerol?
90 g water: 5 moles6,4 g methanol: 0,2 mol18,4 g glycerol; 0,2 molTotal number of moles: 5,4Mole fraction of glycerol: 0,2/5,4=0,037
Is Methanol in crude oil?
Methanol is not typically found in crude oil in significant amounts. It is more commonly produced synthetically or as a byproduct of natural gas processing.
How does caffeine react with methanol?
Caffeine and methanol do not have a significant chemical reaction when combined; instead, they simply coexist in a solution. Caffeine, a stimulant found in coffee and tea, is soluble in methanol, which can be used as a solvent in various chemical processes. However, it's essential to note that methanol is toxic and can pose health risks if ingested. Therefore, any combination should be handled with caution and awareness of methanol's harmful effects.
Why intake of methanol in very small quantities can cause death?
When methanol is ingested, it is metabolized by the body into toxic byproducts that can cause severe metabolic acidosis and damage the optic nerve, leading to blindness or death. Even small amounts of methanol can be lethal due to its toxicity and the body's limited ability to metabolize it safely. Immediate medical treatment is necessary to prevent severe complications and death from methanol poisoning.
What is the dipole moment of methanol and how does it contribute to the molecule's overall polarity?
The dipole moment of methanol is 1.70 D. This means that methanol has a significant separation of positive and negative charges within the molecule, making it polar. The dipole moment contributes to the overall polarity of methanol, making it capable of forming hydrogen bonds and interacting with other polar molecules.
How can one effectively test for methanol in a substance?
One can effectively test for methanol in a substance by using a simple chemical test called the chromic acid test. This test involves mixing the substance with chromic acid and sulfuric acid, and observing a color change to determine the presence of methanol.
Attraction between benzophenone and methanol?
Benzophenone and methanol can exhibit some weak attraction forces, like dipole-dipole interactions due to the polar nature of methanol. However, the strength of these interactions is not as significant as in hydrogen bonding or other stronger types of intermolecular forces.
Why would someone test electrical conductivity with a solution containing both methanol and water?
Methanol can help increase the solubility of certain compounds compared to water alone. Testing conductivity in a mixture of methanol and water can help determine the presence of ions or charged particles in the solution, as both methanol and water can facilitate the movement of ions and enhance conductivity.
Line formula formula for the product of salicylic acid and methanol?
I want to know about, in which formula we can calculate the volume of buffer component like potassium phosphate buffer?
What is composition of papanicolas EA 65?
Component(s): Methanol < 5% Ethanol <87% Phosphotungstic < 1% Eosin Y < 1% Light Green < 1
What is the active ingredient in charcoal fluid?
The flammable component of charcoal starter is either petroleum based solvent or alcohol. Either methanol or ethanol are typically used.
