I need to take some following samples of these:

*a hydrocarbon w/a molecular mass greater than 100 g/mo
*something w/ L-carvone or D-carvone in it
*a non-electrolyte that dissloves in water
*something w/a pressure greater than 2.o atom
*a proton donor
can you help me??

Go down the post list about 13 or 14 questions (not counting any answers) and look for a post by desperate. Bob Pursley answered that question with some good advice as well as some answers.

a proton donor is an acid.
Look on the labels of bottles you have in the house.
Is a soft drink bottle under 2 atm pressure from the CO2.
sugar is a non-electrolyte. Is it soluble in water?

oh thanks!!

wait so what would be an example of an acid? in bottles?

vinegar? a dilute solution of acetic acid.

Yes, vinegar is a good example of an acid that you can find in bottles. It is a dilute solution of acetic acid. Acids typically have a sour taste and can be corrosive. They release protons (H+) when dissolved in water, hence being called proton donors. Other examples of acids that you can find in bottles include lemon juice, battery acid, and stomach acid (in digestive tablets). It's always a good idea to check the labels of bottles you have at home to see if they contain any acids.
