What else can I help you with?
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 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 I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE OF ETHANOL AND WATER?
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)
Will ethanol float or sink?
Ethanol is less dense than water so it will initially float on a water surface. Given that ethanol is totally miscible with water, an ethanol layer on top of a water layer will diffuse into the water while the water will diffuse into the ethanol until a single uniform composition solution of alcohol and water is achieved.
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.
Does ethanol contain water?
Yes, ethanol can contain water as it is a common impurity in ethanol. Ethanol is a type of alcohol that can be mixed with water.
Which two are miscible with one another oil water and ethanol?
Water and ethanol. Oil is immiscible with either of those.
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.
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?
Ethanol+oxygen-carbon dioxide+water
What is the difference of absolute ethanol to the regular technical grade ethanol?
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.
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.
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.
