Describe an experiment used to find out whether there is any temperature change on mixing ethanol and water?

Measure equal amounts of water and ethanol in separate containers. Take temperature of both. Add ethanol to water and take temperature.


Why would ethanol work but not with water when using felt tip pens in an chromatography experiment?

Ethanol would work because it is alcohol-induced, therefore, it is stronger than water.


Which two are miscible with one another oil water and ethanol?

Ethanol is miscible with water, but not oil. Oil is not miscible with water or ethanol.


Which fluid will float 5 kg of ethanol or 1kg of water?

1 kg of water will float in ethanol because ethanol is less dense than water.


How to obtain pure water and ethanol from a mixture of sea water and ethanol?

You would use distillation, in which the ethanol and water will boil at different temperatures.


How do you separat ethanol and water?

Ethanol and water can be separated using distillation. Since ethanol and water have different boiling points, heating the mixture will cause the ethanol to vaporize before the water. The vapor is then collected and condensed back into a liquid form, resulting in separate ethanol and water fractions.


If you put rope in salt water and then burn it will it stay together?

Yes. We did this experiment today and it worked. But I don't know why.


What are the chemicals that are present in the mixture of ethanol and water?

Of course, these substances are ethanol and water.


What is the word equation for burning ethanol?

The word equation for burning ethanol is: ethanol + oxygen -> carbon dioxide + water.


What is the difference of absolute ethanol to the regular technical grade ethanol?

Absolute ethanol is 100% pure ethanol, with no water content, making it suitable for laboratory and industrial uses requiring high purity. Technical grade ethanol, on the other hand, may contain impurities and water, making it more suitable for general industrial applications like cleaning and disinfecting.


Why does ethanol burn differently than ethanol and water mixed?

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.


What is the chemical symbol of ethanol and water?

The chemical symbol for ethanol is C2H5OH. Water does not have a chemical symbol, but its chemical formula is H2O.
