Why does a thin layer of water repel a drop of rubbing alcohol?
A thin layer of water might repel a drop of alcohol, however rubbing alcohol is miscible in water in larger quantities. Isopropyl alcohol, of the form C3H7OH, is what we know as rubbing alcohol. The repulsion could be because of the propyl group, however the hydroxyl group should form intermolecular hydrogen bonds with water.
Is methanol corrosive or irritant?
Methanol is toxic. In moderate quantities it causes blindness, and in larger quantities it causes death. You can describe it as an irritant but that is really an understatement.
Does CH4O have isomers?
No, only alkanes C4H10 and larger have isomers
Why is alcohol used in laboratory thermometer?
Alcohol is non-toxic, economically more viable and can be easily dyed to make it more visible in the capillary tube when it undergoes thermal expansion or contraction, hence it is used in laboratory thermometers. The alcohol used is not absolute ethanol however (ethanol has a boiling point of 78 degrees Celsius, while laboratory thermometers can measure up to 110 degrees Celsius); larger chain alcohols (e.g. isopropyl alcohol) would suggestibly be preferable in this context. This is, however, an obsolete approach to measuring temperature - today, more accurate quantification of temperature may be achieved through temperature sensitive probes with digital readouts.
What is it called when combustion occur in a rocket's engine and releases heat and pressure making a larger pressure gradient inside the rocket than outside which causes the gaseous products?
Thrust occurs when combustion in a rocket's engine releases heat and pressure making a larger pressure gradient inside the rocket than outside which causes the gaseous products?
Where to buy isopropyl alcohol in south Australia?
Small quantities of isopropyl alcohol should be available at pharmacies. Larger quantities from oil companies, or from laboratory supply houses.

How pressure depends on force and area?
Pressure = force/area This means that the larger the force, the larger the pressure. But the smaller the area, the larger the pressure.
Why is methanol more polar than ethanol?
Methane is CH4 or H-CH3 Ethane is CH3-CH3 When compared to H- (in methane), the CH3- (methyl group in ethane) is more electron donating and hence ethane is more basic than methane.
Why is it ethyl alcohol cannot be replaced by methyl alcohol?
If you are mean why methyl alcohol can't be used in beverages then the answers has to do in part with how the body processes alcohols.The body processes ethyl alcohol into substances that are not particularly harmful and can be easily metabolized.The body processes methyl alcohol into formaldehyde, which is toxic and carcinogenic and formic acid, which disrupts the pH of the body.Additionally ingestion of methyl alcohol damages the optic nerve, causing permanent blindness.
Does CH4O have isomers?
No, only alkanes C4H10 and larger have isomers
What is larger atmospheric pressure or sound pressure?
Atmospheric pressure is around 101325 pascals. Usual talking is around 0.04 pascal. You see what is larger.
Does higher pressure make larger tornado's?
No. Stronger tornadoes (which are usually larger) have lower pressure than weak ones.
Why is methanol not synthesised from hydrocarbons?
Because it can't be. Larger alcohols can be formed because of the presence of alkene or alkyne bonds; these can be oxidised in a controlled fashion to form the alcohol. Methane, with only one carbon, cannot have such bonds. Any other method of production is inefficient and has such a low yield and purity that it is not worth the time and expense.
When the area get larger the pressure?
Yes.
Why do skis have a larger surface area?
The larger the surface area the more pressure can be spread out, therefore it is less likely to fall through the snow. As pressure = f / a.
