Is ethanol dissolving in water an exothermic reaction?
YesThe mixing of ethanol with water is an exothermic phenomenon.
How does the rate of mixing copper sulphate in water change with temperature?
The rate will increase as the temperature increases. The dame is true for the opposite.
Water and ethanol can be separated by heating the ethanol until it boils away from the water What type of change is this?
Type your answer here..molecular change
How do you separate Ethanol and water?
Ethanol and water can be separated by fractional distillation. Fractional distillation separates liquid mixtures with different boiling points. Ethanol boils at a lower temperature than water. However, it forms a boiling azeotrope with water (azeotropes occur when solvent mixtures boil at a lower temperature than the component solvents). The azeotrope boils at 77.85 degrees, whereas pure ethanol boils at 78.4 degrees. The azeotrope is 96% ethanol and 4% water by volume. This is the maximum concentration of ethanol that can be achieved by simple distillation. Other methods of separating ethanol from water include using salts to make the water and ethanol phase-separate, using molecular sieves, using additives to change the azeotropic mixture, or distilling dry ethanol from wet ethanol that has been treated with a water-reactive metal, leaving behind the solid metal hydroxide.
Why does the water temperature change less than the land temperature?
Water is able to move (unlike the land's surface), and it can be mixed when it is heated. This mixing can cause the heat that's transferred to the water to be averaged with the rest of the water, which isn't being heated. If you were to dig deep enough into the land's surface, you would find that the temperature of the land changes very little far below the surface.
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.
Is ethanol dissolving in water an exothermic reaction?
YesThe mixing of ethanol with water is an exothermic phenomenon.
What happens when mixing calcium nitrate in water compound?
what is the difference between mixing calcium nitrate in water compound to mixing ethanol in water
When alcohol dissolved in water why temperature of alcohol is increased?
The hydrogen bonds between water molecules and respectively hydrogen bonds between ethanol molecules are broken by mixing; new hydrogen bonds are formed between water and ethanol molecules - this second process is exothermic.
How does the rate of mixing copper sulphate in water change with temperature?
The rate will increase as the temperature increases. The dame is true for the opposite.
What do yout get when mixing table salt baking soda ethanol and water what do I get?

Why is cement not reversible after mixing with water?
mixing cement with water is a irreversible change
Does the pH of ethanol change if water is added?
It should change

Is salt and ethanol a heterogenous solution before mixing?
Almost no salt will dissolve in pure ethanol. If salt is added to a solution of ethanol and water, which are miscible, it may form a homogenous solution without being stirred.
How is ethane obtained from ethanol?
according to me, ethane can't be prepared from ethanol. but you can prepare ethene from ethanol by treating ethanol with conc. H2SO4 (95%) In 440 K Temperature with release of water molecule.
