I know so far that starch has an adehyde group but it is too small in comparison to the rest of its own molecule. The experiment used benedict's solution to determine wheter there was a reaction of glucose or not. Starch did not give a positive glucose test. Why?

Hey!!!

I've put an egg in a glass of vinegar overnight. I've noticed a sort of reddish brown deposit on the shells which peels off easily, but the shell is still here. What is the deposit and why is it of that colour? How much time will it take for the shell to disappear completely. Waiting for your answer!

We all know that a quick and easy way to make cold ice is to put water in the freezer. But take it out and after a while it will warm up and turn back into water. Just as expected.

My exact question is: If you could compress an amount of water into ice - then put that newly compressed ice in a perfect fitting container that would not let the ice expand back into water; Would the ice inside the container stay permently cold? or would the ice in the container warm up to it's surroundings but stay in its solid state?

okay, my professor is having me and another guy make some posters for our lab for extra credit. He wants us to come up with some ideas for them, then we are going to make them in Powerpoint.

We may be doing one with some techniques on them on how to do titrations, and some other things.

The other guy thought of a Do's and Dont's poster, but im not entirely sure what all we would put on that.

I will probably go through all the labs we had done earlier in the year again and try to find some things, and we may make one that shows some safety things like the fume hood, shower, eye wash exc.

Anyone have any more ideas of something that would be good for a chem lab? Its basic college chem 1 and 2.
