Okay so because of the difference in density a simple method for telling the difference between the two is to put a sample in a container with oil, because water has a higher density than the oil it would sink to the bottom but alcohol on the other hand is lighter than oil and would float on top of the oil.
However with this question I think that what you would do is use the ice to find out what the substance is, it would float on top of the liquid if it were water because the water is denser than ice but the ice would sink if it was alcohol because the alcohol is less dense than ice.
I hope this helps you, good luck : )
Answer:
Water acutually has a higher boiling point because CO2 will turn into a gas form at a certain temp ( -78 C), so CO2 wouldn't really boil very long.
Hope this helps:)
TBH i dont know but can you give advice to get more points on this site
I believe it is D. because stoichiometry allows people to determine how much reactant is consumed in a chemical reaction.
